Hi guys I've just started to build my first antweight and I thought I'd start a thread so any other builders can tell me if I made any fatal mistakes
-
hiya, good luck with your build, feel free to ignore or take my advice :laughing
noticed one alreday, using far too heavy parts that arent that strong.
-
I'm getting some money to buy better parts soon, are there any you could suggest ?
-
well would you want, good, better or best?
-
I'll have around £100 to spend so the best I can get with that
btw I already have radio equipment
-
if you have plannat 5 i may have to slap you ;)
with £100 you could easily have a very competitive robot for the aws's
2 or 4 50:1 ebay polu motors, £5 each
pete waller esc (2 wheels) - £30-£50 or sabertooth 5a (4 wheels) £50
2 or 4 polu wheels, £6 a pair
7.4v lipos (120-300mah) about £3-8
lipo charger £20
any questions?
-
I have 1 question: would all of the components fit onto a planet 0 radio reciever or would I have to do some soldering ?
-
and I was going to use some of the radio equipment from my school but as soon as my teacher said ''umbilical chord'' I had to resist the urge to slap him
-
Receiver (http://www.hobbyking.com/hobbyking/store/%5F%5F11965%5F%5FOrangeRx%5FR610%5FSpektrum%5FDSM2%5F6Ch%5F2%5F4Ghz%5FReceiver%5Fw%5FSat%5FPort%5F.html)
Remote (http://mobile.robotmarketplace.com/0-SPM5500.html)
Speed Controller (http://www.robotmarketplace.com/products/0-FT-TINYESC-V2.html) you'll need two of them
Drive Motors (http://www.robotmarketplace.com/products/0-FT-SSPARK-22.html) once again you'll need two or more
Motor Mounts (http://kitbots.com/product.sc;jsessionid=990C54DA81957EAF8C009CAF3883A08C.qscstrfrnt01?productId=24&categoryId=1)
Wheels (http://www.robotcombat.com/products/lite_flite_wheels.html) Pick a size that fits your design
Battery (some lipo from Hobby King (http://=http://www.hobbyking.com) between 300-500mah
This stuff should help point you in the right direction and towards building a competitive 1lb antweight.
-
err SKBT i think he lives in the UK, does hobbyking ship outside the US?
-
hobby king is a austrailian site, robotmarket place is us.
with those you will need to solder. do you want the links?
-
Hobby King is a Chinese manufacturer and warehouse distributor company based out of Hong Kong but have warehouses all over the world. Finger Tech is based in Saskatoon Canada and Kitbots is in North Carolina USA.
-
Yes please ( to the links )
And how would I do the soldering or should I just ask my DT teacher because he has alot of experience in building heavyweight robots ?
-
your dt teacher builds hws? nice mate, ask him about most things.
you end up soldering like 4 wires so you can do it nice and simple, if you have msn let me know and i will explain everything, links in a secture
-
I donthave msn so oculd you send me an email to: ggonline19@yahoo.co.uk
and my teacher used to build heavyweights ( he built major tom ) but now he's my dt teacher
-
email sent :approve:
-
He built Major Tom :OOO
-
yeah but he stripped the electronics out years ago and the shell is barely standing according to him :(
-
Your teacher built Major Tom? awesome
-
I've just ordered the servos and the 1mm polycarbonate
I was thinking of making one of these two ideas
but can anyone tell me how i would get the sharp edges on the wedge ?
-
2nd idea :
-
what do you mean buy sharp edges, its plastic so it wont be sharp
-
i meant the edge for a decent wedge
-
nick some of those lamanating sheets of thin plastic and then put that on the polycarbonate for 0mm ground clearence
-
thanks
-
best to replace them after spinners get to them though
-
it shouldnt be going up against any spinners because i only plan on entering roaming robots because theres nowhere to fight it near me :(
-
well antweight events move around a lot more than roaming robots
-
could you send me the links to some of them please because the next roaming robots close to me is in november
-
there arent many as its the end of the year (ish)
aws bristol
atc oxfordshire
-
I'll have to start entering it regularly next year then because im nowhere near bristol or oxfordshire :(
-
2nd idea :
This is probably the better design.
-
how would i get the good edge for the wedge though because i was going to bend it and sand it down but is there a way i could attach two pieces together to make a good wedge ?
-
why sand it down?
-
to try and get a straight edge
-
on polycarb? scissors seem to cut it pretty staight ;)
-
i meant like the lip on the wedge
-
with a 1mm material there isnt much point, its easyer to put paper or thin plasitc on the front instead
-
ok thanks i'll just do that then
-
just signed up for roaming robots at maidstone and I'm getting my antweight there from haz so it will be my first time driving it. fingers crossed i dont get annihalated :trollface
-
doubt it, ill build it strong! you can always drive mine if you are foolish enough :laughing
-
Nice, what's the bot style going to be? Hammer, lifter, flipper, spinner...?
-
I asked for a flipper but that's all I know
You'll have to ask haz any other questions
-
yes its gonna be a flipper, mate, do you just want a basic wedge flipper? do you want me to build from a design or just to have a drink, and see what works :laughing
everything is ordered btw
-
Can you try to do a full body wedge type thing please ?
Or whatever would work well.
-
just got back from roaming robots at maidstone as the winner of the antweight annihalator, beating haz in the process :trollface
-
pics?

Nice going dude.

Thanks

Congrats on the win, but now its....
Stupid Question Time TM
Why is it that every GTM member who has a robot IRL except haz has done extremely well in tourneys? Vertigo's got a crazy number of wins, I've never failed to place in the top three, and Mikes placed highly in many tourneys.

I'm not sure to be honest But that does seem to be the case most of the time
-
Simple. GTM people are just at least 50% more awesome... Haz just has some kind of permanent debuff that causes a -50%.
-

I think the reason haz hasn't done very well in tournaments is because of the bane of his robotic existence which will remain unnamed, "cough" explosion "cough"
-
Because haz doesn't really play RA2.
Although now that I think about it I can't remember seeing any bots from plazmic either. But he's newer. Got that new member smell.
-
Winning an ant fight really isn't something to brag about, sorry :P
And I was too busy to use mine at Maidstone, you still have that joy to come

Well there's only three of us, just co-incidence really
-
I know its not much to brag about, I was just happy because it was my very first fight with any antweight and I only plan on making antweights anyway :P
-
just noticed I have enough parts to make another antweight flipper, all I need is a servo for the flipper, any suggestions on what servo I should use because I really don't know
-
HPXF
-
just ordered a towerpro mg16r from giantcod
-
got all the parts now, i'm going to start work on it tomorrow with around 50-55 grams for armor.
any suggestions for shape ?
-
Do something like Wheely Big Cheese.
-
Do something like Wheely Big Cheese.
the only problem with that is that I already have an antweight with a similar design to wheeley big cheese and it would be incredibly hard for it to self right without an external attachment to the flipper
-
Hm.
Maybe something like Toro then. Toro flippers haven't hit any sort of stride in the UK and you could change that.

Hmm I might have to give that a go
-
Don't 'Toro' style flippers are more mechanically efficient but they don't get as much throw compaired to a UK style flipper. Trust me, my flipper 'Phoenix' has a larger ram than Vertigo's flipper 'Explosion' but gets less height and distance its flips.
-
Okay, I think I'll just cut out some different styles of flipper tomorrow and attach them and see which works the best.

Ram size is only one factor affecting a flipper's power
Ram Size + Chassis Design + Amount of Expansion Room + Amount of Flow = Flipper Power
Your flipper is about 10 times less powerful than Explosion due to the lack of a buffer tank :P
On an antweight, your flipper power is atleast 80% decided by the power of the servo, so the design does not matter a huge amount
Go for whatever design you like
-
I got the drive sorted out today so tommorow i'll start on the body and flipper, unfortunately I can only work on it an hour a day but i've got a friend to help so it should be done either tomorrow or wednsday
edit: my cousin also came round today and decided he wants his own antweight so he's asked me to build him one for his birthday, im thinking a clusterbot rambot so him and his little sister can both use it at the same time and maybe fight my antweight at some point. ( i'm trying to get my family into antweights )
-
attached the drive servos temporarily to the base with double sided tape and the same with the flipper servo, i've also just ordered a hot glue gun so I can actually work on the robot at home.
-
its not finished but any name suggestions ?

it looks big :laughing
go for a long and funny name, always best
-
it looks big :laughing
go for a long and funny name, always best
its about the same size as masochist, and I might call it anarchist
-
I cannot see how that can possibly fit into the four inch cube

I cannot see how that can possibly fit into the four inch cube
its only the flipper that wont fit and its only a temporary thing until my hot glue gun arrives

a video of anarchist, I still need to add side armor but I need to drill some holes in the flipper first to leave some weight for side armor

Yeah, I just meant in the style of cheapy robotics :P
-
I decided today on a complete rebuild on anarchist tomorrow because it was too big and the baseplate flexed too much because of the shape and basically reduced its flipping ability to nearly nothing, so I'm going to go fore a wider and shorter baseplate and a completely new flipper that i'll make on wednesday
-
anarchist is now officially going to be a spinner after the new year, hopefully invertible, i'm going to buy a disc for it from will thomas, the whole rebuild should cost about £40-£50 depending on the price of the disc
-
*Sigh*
-
theres no need to sigh i'm only building one spinner i'm not becoming a spinner fanboy
-
i promise i havent been talking to him :laughing
-
good news everyone, I might be buying daiske2 from tony smith, and if someone else gets it the build on minor tom will start as soon as everything that I will be ordering arrives
-
Right, there is what I see as two problems here:
For a start, lets just clarify that you've never built a serious robot yourself
To attempt to build a spinner for your first robot I see as a bad idea. They can be very dangerous even at the 150g level and could quite easily result in you having a missing finger. I would advise building something such as a servo driven flipper first yourself, and doing the best job possible i.e. Not simply taping components to a piece of HDPE. Secondly, if you are going to attempt a featherweight robot, build it yourself! By buying anything you ever compete with you will not learn, and not feel any sense of accomplishment.
Please do not take this the wrong way, and of course ultimately it's your decision. All I'm trying to do is give some advice, what I would do, and point you towards the best possible direction :)
-
I have already built a flipper myself and thats what i'm converting into a spinner
-
I have already built a flipper myself and thats what i'm converting into a spinner
I know and appreciate that :P, what I'm advising is to make one a little more professionally (i.e. held together with screws, not glue gun), because I'd hate to see what someone can do with a glue-gunned spinning blade
-
Anarchist will be held together with screws as soon as I get back to school because it's going through a complete rebuild so it is better than a glue gun manufactured accident waiting to happen, the spinner will be held together with screws as well
-
dont worry, he is getting the disc made.
also, its really the motors and frame he is getting, it needs quite a bit of work
said it before and i'll say it again, nowt wrong with hot glue
-
Forgot to mention that :p
-
dont worry, he is getting the disc made.
also, its really the motors and frame he is getting, it needs quite a bit of work
said it before and i'll say it again, nowt wright with hot glue
:P
-
i secretly love hot glue, i just cannot handle the awesomeness
-

:P
That would have been funny if it was spelt correctly :gawe:
-
I now have a dilema, I either want to rebuild anarchist as a lightning style flipper because i've never seen an antweight like that before or completely convert it into a spinner.
PLEASE HELP :confused:
-
don't bother, with a lightning style flipper, wont be very efective as paralax proved, was cool though.
spinner!
-
Ultimately it's your choice
Personally, I would build something like a flipper *properly* (i.e with screws), before attempting a spinner. I see spinners as dangerous, robots capable of chopping off your fingers. I'd hate to see one held together with glue.
But like I say, it's your choice completely, but I'd definitely advise against making a side flipper
-
Don't do a Lightning style flipper. The thing that makes flippers entertaining and effective is that they are able to control the flow of the fight. A Lightning style flipper cannot do this as effectively as s regular style flipper because instead of launching the opposing robot away from it, it throws the opposing robot off to the side where then the opposing robot is in a better position to get under your robot or flank it and cause damage to it.
If you dont fight in an arena with "pushouts", ignore this.
Spinners tend to "hockey puck" and or gyro dance after a big hit or if they get tilted too far and the gyroscopic forces of the spinning mass take over. During these times you have no control of your robot. Because there are "pushouts" you spinner could gyrodance it's way put of the arena for an incredibly stupid loss.
Spinners also need to be able to absorb and disapate whatever KE they dish out, otherwise stuff will break on your bot. Seeing your construction methods, you aren't at the skill level where you can effectively build a flipper.
If there are pushouts in the arena the best design would be a fast and powerful pushy bot or a clamp of some sort, if there are not pushouts, go with a flipper.
-
sorry guys, I keep forgetting to put ito posts that i'm properly rebuilding anarchist with screws rather than hot glue before i even think about building a spinner because i'd rather have something i know is safe over a hot glue manufactured accident waiting to happen
-
Good call. Also, shipping may take a while, but this stuff is very handy-

Currently using it on Motor City Massacre and Apollyon, and planning to use more on Nyx. (Apollyon and Nyx use larger versions)
-
thanks but I think i'm going to make the top of the shell as 1 piece by bending hdpe with a heat bar and just screw it through the baseplate, might use those in the future though
-
You can bend HDPE with your hands :P
-
i know, i just like using a heat bar
-
guys, how would I go about getting paint off of 6mm polycarb ?
-
sand paper
-
I have a dilemma guys, a set of 12v drill motors with mounts and 75mm robochallenge wheels have just come up for sale, should i get these, run them for a while and then upgrade to the gimson robotics motors later or should I just spend the extra money on the gimson motors from the start ?
-
Personally, I'd wait until the gimsons have been proved in combat. I'm not saying that they're shoddy or anything, just new. :P
-
Get the gimsons
-
They look like they're based on cordless drills with mods focused on improving durability and ease of mounting. Unless they cut some major corners internally, they'll probably hold up better than plain cordless drill gearboxes.
-
gimsons
-
now i'm not sure on whether to make my ant a bar spinner or a shell spinner when I build it, mainly because i've never seen an antweight shell spinner ( maybe for a very good reason ) and i'd like to see how it would do
-
shell spinner is fbs?
there have been a few, quite good but more expensive than a bar. i sort of combined the two in a flea
-
I think the problem lies with invertibility/self-righting.
And the size

Assuming you mean UK ant, there's a few-

http://buildersdb.com/botdetails.asp?botid=4080 (http://buildersdb.com/botdetails.asp?botid=4080)
I imagine it's mostly an issue of finding the weight for a shell that's strong enough to survive and a baseplate that's strong enough to handle the hits at that size.
-
yay for RCD's robots :claping
-
once i've got the motor, lipo, etc i think i'll just try a few different spinner types and see how it goes but i'll start off with a simple bar spinner
-
Can also try an ant ringspinner.
-
Can also try an ant ringspinner.
I'd probably reccommend attempting something simpler
-
Just an idea. Think it would be fun to see something like it.
-
had another idea for minor tom's shell,(https://gametechmods.com/uploads/images/53491minor tom shell 2.jpg)
construction should start in the next week or so and I should have it running as soon as I can afford the esc's
-
that's like the exact chassis on F-Zero :P
-
that was meant to be a secret until after BoF2 ;)
and I thought it would work well as an invertible rambot
-
Just a little tip, it's generally better to build the chassis around the components ;)
-
i'm going to, i'm just thinking of a few basic shape ideas before my workshop is cleared out
-
I need your guys opinions on this, should I wait and save for my feather's esc's or should I start work on my antweight spinner because I have just about enough money to finish it ?
edit: this is what I have been working on in dt for about a month too: http://www.youtube.com/watch?v=cC3l9NHUrFQ&feature=related#ws (http://www.youtube.com/watch?v=cC3l9NHUrFQ&feature=related#ws)
-
featherweight
-
okay
-
featherweight
-
guys, when I dohave the money for he esc's which one/ones should i get ?
2 of the the electronize 30a or the scopion xl ?
the scorpion xl is cheaper and looks easier to set up
-
and would I be able to wire 2 batteries at different voltages in series, e.g a 6v battery and a 12v battery or would that cause a short ? because if it won't i'm going to wire them in series tomorrow as batteries for my featherweight
-
going to start work on minor tom's shell today with this shape:
(https://gametechmods.com/uploads/images/92491minor tom shell.jpg)
not sure on dimensions yet
-
Bad idea... work out your dimensions before you cut anything. Make a CAD first. And by CAD I mean cardboard assisted design. Lay out all your parts on a piece of cardboard larger than your planned size. Arrange your robots parts in their planned configuration on the cardboard, and cut it down to the smallest size, while still protecting your components. And that's just one way to size your robot.
-
i'm going to do that first now, thanks for the help, I can't start work on the actual hdpe version for at least a week now anyways
edit: just ordered a scorpion xl and am going to make the cardboard model as soon as i can find a decent ammount of cardboard
( see vertigo hot glue is good for something )
-
Recently found out that I won't be finishing my fw for a while so I'm going to focus on my antweight builds for now, I'm going to build a spinner and change the flipper I'm part way through building into a front hinged flipper With hdpe armour
-
Can someone link me to an esc for an antweight and a brushless esc for a turnigy 19g outrunner ?

-
Thanks, are the tinyesc's single or dual motor esc's ?
-
Single, so you need two of them
If you want a dual motor speed controller, you can get the Sabretooth of technobots which seem to be more commonly used in the UK
You'd be better off asking on RW101
-
that brushless is waaaay overkill. i run a tiny 6a thing, barely gets warm
-
so i've decided i'm turning my current ants into working rw replicas possibilities so far:
disc o inferno
fluffy
firestorm
vader
mute
chaos 2
i'm open to sugestions

got my shed cleared out and i can now finally get to work on the featherweight
i'll put some pics up after the hdpe i painted dries and i air out the shed

the materials for building minor tom:
(https://gametechmods.com/uploads/images/35505minor tom materials.jpg)
-
Looks alright. I'm by no means an expert, but that white stuff looks quite thick. [/outofcontext]
Are you going to put one of the little table football guys on the top for a head? =D
-
I might have to, and it's 10 and 15 mm hdpe
-
now i truly believe that the internet is trolling me, 2 30a esc's come up for sale in the few days after i spent the money that could have got me them ::2mad ::2mad
-
On the bright side, at least you have HDPE sheets!
-
indeed, hdpe ftw !!!!!!!
-
progress has been made !!!!
got the battery packs soldered:
(https://gametechmods.com/uploads/images/99456battery soldering.jpg)
now waiting for my heatshrink to arrive
and a few days ago the shell arrived:
(https://gametechmods.com/uploads/images/65500minor tom shell.JPG)
-
got home from open evening at my school and I took minor tom along with me to show a robot in mid build and it generated a lot of interest
-
QP.
Had some good news today, in the next few days I should have the money to buy the last esc and charger for minor tom and then it should be up and running within a few days of the parts arriving :bigsmile:
-
Cover it in cardboard. They won't know what hit 'em.
-
He already has armor and cardboard won't cut it for a combat robot
-
I think he means put cardboard over the armour that is already on it so that other drivers don't know what they are fighting
-
Damn it's been a while since I updated here, I've accepted that I won't have minor tom ready for maidstone so i'm waiting until after the new year to start anew and make a pneumatic 4bar lifter, for now i'm focusing on my antweights, first off is Valefor
(credit to gaz for the name) which will be a rebuild of masochist but front hinged instead and second is an un named antweight bar spinner that will be finished after the 21st of october.
edit: The armour for Valefor will be 3mm ABS welded together with a soldering iron.
-
I know I need to get it running properly first and the only reason it won't be completed by then is because of money and I was actually going to ask around the fra forums for information on pneumatics before going ahead with planning, ordering parts, etc
-
Unregulated co2 is f***ing scary. Even if you know what you are doing.

I have a question about my antweights batteries, how long would I need to charge a 4.8v 210mah battery on the charger at the top for it to be charged fully ?

what do you mean there a bit of an issue ?

They tend to be slow. They work, but robots that use motors and ESCs instead of constant rotation servos will run circles around them.
-
I know, I've done fine with a servo driven ant before and I couldn't afford esc's so these'll have to do for now.
-
ordered about £100 of antweight stuff and the parts I ordered are going into this:
(https://gametechmods.com/uploads/images/78325Mini Tom Sheck.jpg)
it's going to run off 50:1 pololu motors, aluminium wedge,12a botbitz esc's, 2mm hdpe base and 4mm hdpe sides and top.
and I'm going to build a mini kronic using the same parts but with full 4mm hdpe armour and flipper arm.
-
Got the okay from Alan yesterday and all of the plastic for the ants arrived today as well as the M2 tap so I'll start contruction in the next few days when I'm feeling a bit better.

Been quite a while since an update so here's what's gone on robotics wise lately:
I am buying aftershock 4 from will thomas next week, I have disc design's for antweights (Thanks to haz), the wiring on minor tom is finished, all I need now is a battery and it's good to go so soon I should have 2 feathers running.
-
TP.
Guess what I picked up today:

Are you signed up for the UK champs?
Unfortunately not as I couldn't arrange transport and missed signups completely, I'll definitely be at burgess hill and the champs next year though.
-
Yeah, more time to get everything ready though and learn the in's and out's of the bot before I use it in a full combat event.

Got spare armour for minor tom now as my school was throwing away sheets of 4mm steel so I grabbed as many as I could (about 17 which made for a very awkward bus ride home) and they are the perfect size to cover the front and sides of minor tom. The equipment to wire minor tom is on the way as well so it should be up and running in the next week or so.

Soldering iron and bolts arrived today for antweights so tomorrow I'll be building this:

With pololu motors and wheels for drive, 2mm base and top, 4mm sides and 4mm flipper arm (all hdpe), not sure on what flipper servo to go for though can you guys suggest any?

Done a lot of work on Minor Tom this weekend, Got most of the wiring done, got the paint taken off ready for a new paint job after burgess hill and got some lifter testing done: http://www.dailymotion.com/video/xz737e_minor-tom-lifter-testing_tech (http://www.dailymotion.com/video/xz737e_minor-tom-lifter-testing_tech)
Should hopefully get some drive testing done in the next few days.
-
Why not use youtube?
-
No matter what format I try to upload in it rejects the file.
-
why u no use pneumatics?
lifter looks super slow. like too slow to be useful slow.
-
Pneumatics are too expensive and scare me. The lifter is made for lifting power over speed as well, It's managed to lift 120kg. I'll be building a new bot for the champs soon and I'm looking into pneumatics but taking it slowly since I'd rather not hurt myself more than I already have. The lifter would actually be useful in 1 on 1 fights because it would allow control of the opponent but not so much in the majority of events where there are around 10-15 bots in the arena.
-

Burgess Hill was a great event, had a great time and even got to test Minor Tom fully (thanks to Haz)
http://www.dailymotion.com/video/xzhmii_minor-tom-testing_tech (http://www.dailymotion.com/video/xzhmii_minor-tom-testing_tech)
Got some good advice during the two days and got some ideas on general upgrades for the champs and future events, it will be competing in october and upgrades will be done after the event. I'll also be starting a build of my own after Maidstone, probably a rammer but I'm learning about pneumatics in my free time so I will hopefully be able to safely build a pneumatic machine in the future.

That's one ant ready.

Looks solid.

Did this last night with some help from Haz:
(https://gametechmods.com/uploads/images/22723Half%20cluster.png)
It's going to have gimson 18v drive, doubled up banebots wheels, 5mm steel wedge ant top, 15mm hdpe sides and back with a 10mm base. It's going to be difficult keeping it to 6.6kg but it'll be something different to take the the champs.
-
6.6kg?
It's half of a cluster.
-
We're not making it to win, we're making it to bring something different to fights, Conraa is making the other half.
-
Progress has been made, batteries are being sent, motors are ordered, going for a 10mm hdpe lid now, escs' are on the way, all I need now is a charger and I'll be good to go with the build.
-
Update time, the cluster is all here, I can't start building the chassis until next weekend though. I have however been repainting minor tom over the past 2 days.

Post burgess hill Minor Tom is looking a little worse for wear. As far as fights go, with Craaig driving he managed to topple and immobilise flow but inevitably get flipped and pitted. When marty drove he got caught by tinyhurtz which snapped one of the lid mounts and hit a battery causing a lot of smoke, to top it all off a rammer managed to push Minor Tom and 2 other bots onto the floor flipper after that leaving the panel hanging off Minor tom and the smoke growing quite violent.
On the second day I missed the first fight as I was repairing the lid as much as possible, the second fight of the day was okay however I wasn't aware someone had hit the pit release and in the delay between it being hit and dropping I got one wheel caught on the edge so I ended up in the pit, second fight was similar but I toppled Mini Mighty Mouse and accidentally drove myself and a rammer into the pit because depth perception.
Overall it was pretty good, everything held up mechanically even after minor tom hit the ceiling of the arena which is good, does need 2 new cells in it's pack though but that's a simple fix. Some new lid mounts and a repaint are also in order.

Nice motor is nice. Drive motors and wheels are ordered and on the way as well.
-
Are the wires compatible with one another? Also, what receiver do you use?
-
Looks awesome. You have the bullet connectors for the ESC?
-
Are the wires compatible with one another? Also, what receiver do you use?
Not in their currrent state, no, the esc needs some female bullet connectors so the motor can plug into it, and for this I'll either be using the transmitter/receiver from minor tom which is just a cheapo giant shark one or a planet 5 set depending on whether minor tom is running for bluewater or not.
-
(http://i.imgur.com/VfZJ38b.jpg)
Terminus is finally robot looking once again, it's getting a new hardox bar before bluewater but there won't be an arena there so it's likely that it won't see full combat until some time next year.
-
Looks sleek and awesome
-
Awesomeness. How much of the chassis I sold you is left?
-

Only the weapon bulkheads really since the motor mounts act as the sides and it's got a new lid and baseplate.
-
Bluewater was a really good event, Minor Tom worked extremely well doing decently in most fights and the lifter was actually useful which amazed me. I will be putting a better motor into the actuator soon which should make the lifter faster and it might fix the self righting problem, if not I'll have to figure something out since self righting is the only issue with minor tom at the moment other than the concave lid.
Now bluewater is over Minor Tom will be getting some tlc before the next event, definitely a new lid mounting solution and maybe a completely new hardox version of the current shell.
-
We all know how much he'll appreciate the tlc :P

Have you finished Terminus yet?

Are you worried about the thinner ends of your wheel guards getting bent over into the wheels? I don't know the thicknesses and stuff but it seems like it wouldn't be too hard to lock up your front wheels that way.

it's 5mm alu and 10mm hdpe so I doubt they'd get bent far back enough to lock up the wheels, even if that does happen, because of the belt drive I'd still have some sort of movement albeit slow movement.
-
True. As long as there's enough torque in the motor to keep the belt moving over the locked hub. Are you SOL if you lose the belt though?

Decided to do a drum after ash and after a days work in inventor I ended up with this:
(http://i.imgur.com/aMGszLv.png)
(http://i.imgur.com/lDnxP0f.png)
The pulley is turned into the drum and the teeth are bolt on via slots milled into the drum and holes drilled/tapped into those slots. Side armour will depends on how much weight is left over but it's looking alright for some hdpe outer armour with the frame equating to about 500g without the weapon and 900g with it.

Burgess Hill event report:
I had both Beetle spinners ready for burgess, only for things to go wrong at the last possible second, Terminus and Ash both refused to run on orange receivers because of the becs I was using, Terminus blew a lipo somehow, Ash's wheels turned out to be just too small to be effective. Although with a large amount of help from Dave we managed to get Ash running using a receiver pack and a borrowed receiver from Headbanger, hence the tape lid for all of it's fights. Every bot had issues at some point apart from Headbanger and Limpet, RPM smoked it's brushless motor somehow and lost one H-bridge on one of the controllers removing the ability to reverse it's left motor, Snappy lost a couple of wire connections just before doing a final demo fight after a day of fighting ash and ramming things, Naff was taken out by ash after I righted it using the weapon on Rory's request.
In terms of Ash's effectiveness I think with a bit of tweaking it could be a competitive beetle, currently it needs bigger wheels, a new baseplate/lid, a few holes drilled into the bulkheads to allow wires to pass through, and a new wedge to replace the 4mm steel on it currently has. For a bot that barely worked though it did pretty well in it's fights against Mr Snappy:
http://www.youtube.com/watch?v=TOBYvPLrWDI# (http://www.youtube.com/watch?v=TOBYvPLrWDI#)
The downfall of Ash in one of the fights was the small wheels causing it to get stuck on the lips between the arena floor tiles, the other time was the receiver pack running flat during the fight, which was a shame as Ash really got some nice hits then.
Managed to take some gouges out of the ali backplate and hdpe:

Been a while since I posted here, not much has gone on except for finishing off Hyperion:
(http://i.imgur.com/ryCCj3Dl.jpg)
All that's left to do now before the champs is to put Ash back together now Haz has done some nice pocketing to free up weight for a bigger weapon.
Plans for after the champs are either build a new big vs or this:
(http://i.imgur.com/OWth7qPl.png)
If I do build this I am going to need to lower the drum and move it forward so an opponent doesn't have to ride the full length of the wedge to get hit by the weapon.

BW Champs Write up:
My champs pretty much started the day before the champs with me going on the 5 hour train/coach journey down to Craaigs and helping him get Mr Snappy 2 going. While we were doing that however I was replacing a broken aerial on my dx6i when I knocked it off the table and snapped the bind switch and broke the switch itself, this meant that once again Terminus could not fight (100% convinced this thing is cursed now). Hyperion however was working perfectly fine and already had it's receiver bound to my 6i so I could still run it as long as the receiver was okay.
Fast forward to the champs and everything looked to be ready for Hyperion so I put the batteries on charge and awaited the draw. The draw was a mixed bag really, most of the heavy spinners seemed to be spread out amongst the fights and there weren't really any 2 big spinners in the same fight in most cases. In my first fight however I was against Spin Cycle ( a HS that Haz built that is essentially Newton with a slightly different frame) and Pisces which was a HDPE rammer. 2 bots went through from this fight so me and Jamie ended up taking out Pisces first and immobilising it, however for whatever reason the fight was continued and I was threatened with disqualification if I didn't go after and hit Spin Cycle, so I did and threw it, taking a chunk out of the disc and stopping it entirely. After that fight the judges went and spoke to the driver of Pisces and determined that Pisces was still mobile while Spin cycle was not after I hit it, so Hyperion and Pisces went through while Spin Cycle was spent to the losers bracket. To put it in perspective Pisces had to pull out of the next fight because of the damage caused.
Fight 2 was against Lynx and Hit & Miss. Lynx was a pretty nice drum but it was plagued with issues from the get go, in it's first fight smoke bellowed from the motor when it spun up because of a screw resting on the case of the brushless and once that was fixed and the drum was working the only belt that Sam brought with him was snapped by Spin Cycle so it was weaponless in our fight. Hit and Miss was a mainly HDPE lifter with a steel wedge.
After activate was called I spun up and went straight for Hit and Miss sending it about 3 feet into a wall, it was still moving though so I hit it again and sent it another few feet and that hit apparently pulled the link out of it so it was immobilised and out. Lynx was a tricky bot to deal with because of the ablative ring around the main body, any time Hyperions weapon would touch it the ring would simply take all of the force from the hit and move out of the way, after enough hits on it though it was bent upwards and I got a nice hit on the body sending it up off the ground and falling back onto the weapon again forcing some fancy gymnastics. After that Lynx drove to the opposite end of the arena and I landed a similar hit forcing Sam to tap rather than take un-necessary damage.
My 3rd fight (quarter finals) was where I unfortunately went out fo the competition, I was using a relatively small motor to power the weapon (NTM 28-26) and as a result of that the shaft on it was relatively thin at only 3mm and 2.5mm at it's thinnest point. This was the downfall of Hyperion as I went after Spinza (bar spinner) at the beginning of the fight as I knew I spun up faster, I hit Spinza and the shock from the hit snapped the motor shaft at it's thinnest point and ejected the motor shaft and pulley into Spinza's weapon slot leaving me weaponless. I still continued though and pitted Incomplete Control but as I was driving towards myself to pit it and couldn't see Hyperion I drove too far forward and Hyperion just tipped into the pit with Incomplete control eliminating me from the competition.
I'm pretty happy with Hyperion, spins up fast, hits decently hard and is really nice to drive as it doesn't gyro at all. The only improvement I have planned is a larger motor with a thicker shaft as nothing else really faltered throughout any of my fights.
Next bot I have planned is this drum:
(http://i.imgur.com/8OnCTh9l.png)
400g or so in the drum with m10 countersunk bolts for teeth, ablative side armour will be added once the frame is with me.
