OK, After several years of dreaming and planning this is it, I finally have an ant in the works. The link to the build will be here shortly.
Team history:
2010-Reptillian Robotics (no bots built, one antweight planned)
2011-early 2012 Team Ninja Force (no bots built, one ant planned)
late 2012-??? Team Ignition (out of planning stage, buying parts ASAP)
-
there is a topic already for good starting parts recommended by Zip
he used the same stuff on his quite successful VS robots
-
Best thing to do is check out VDD's website.
-
Talk to Zip and join a real robotics forum. I'm no help. Smallest thing I've built is 30 times heavier than what you want to build.

Planning to make an AW wedge/thwack called The Anole. I wanted to use this as a start:
http://robotcombat.com/products/package05.html (http://robotcombat.com/products/package05.html)
What do you guys think?
-
Don't get it. That gearbox is crappy, the radio system is outdated, the wheels are heavy, and I don't like sabertooth speed controlers.
Also don't build a thwack bot you'd be better off with a wedge without the thwack ability. (more weight for thicker wedge)
-
ah. I see...
what about this one?

I can tell you the Laser 75MHz radio is bad. You want to get a 2.4GHZ radio http://www.robotmarketplace.com/products/0-SPM5500.html (http://www.robotmarketplace.com/products/0-SPM5500.html) and a compatible receiver. They hop frequencies and are mostly glitch free. Unlike the standard 75MHz.
I don't know what are good drive motors for antweights but this might be able to help http://www.architeuthis-dux.org/torquecalc.asp (http://www.architeuthis-dux.org/torquecalc.asp)
Just find the motor you want to use on the list fill it out and see if it meets your requirements.

thanks.
-
Good luck with creating your robot. I bet it would look great when finished.
-
you know those kits are overpriced IMO
follow Zip's AW part suggestions and you will come out at half the cost
-
Just did all the calculations, if I can get some chassis and armor materials free from my dad, an AW VS will cost me only $163.73 USD. Thanks guys.

Planning to build one or two ants over the summer, maybe a fairy too. Depends on how much cash I have in my bank account (should be around $400 now, got the account last year)
-
You might get one ant out of $400 if you are frugal with your money. A radio/receiver and ESC combo for an ant will run you around around $130 alone.
-
my previous calculations go to around 175 unless I'm missing something
Also planning to make a joke bot outta a mini RC car. Like a mini metal brick thing. Just for the lulz.
-
don't, far too many people do and have done that
-
But that's not gonna be my only bot though... (read plz)
-
plans for first bot, no electronics or anything yet
(https://gametechmods.com/uploads/images/51847botplans%20basilisk.PNG)
Thoughts?
-
not to sound rude but i cant really tell what your design is...
-
Looks like a VS. Can't really tell though :/
-
To me, it looks like an invertible wedge with a VS on the vertical side.
-
Yeah, you got it. It's invertible too.
Sorry about the bad pic, I was rushed
-
cool, where you getting the blade made?
-
My dad's pretty good with metal and stuff, I could probably get him to make it (for free :D)
-
Why, can't he just print out a piece of paper with the disc design and tape it down and drill it?
-
Nooo
You need it balanced, which means made professionally, from a CAD or something

-
This looks suspiciously like Sparkey's drawings...
-
it was rushed, geez...
-
DP, bump but its my own thread so who cares
got about 200 bucks for my birthday, planning to buy all the bot stuff using it :P all I know right now is that it will be an AW VS (my dad is a professional mechanic, I'm sure we can make an even blade)
also for a LOLbot planning to take an RC car and make a metal shell for it that looks like EMERGENCY :P maybe with interchangable shell for SFTW etc. should be hilarious. Not going to any events till the VS is finished though
-
For the serious bot, what are you planning for radio gear/drive/batteries/speed control etc...?
-
For radio gear This (http://www.hobbyking.com/hobbyking/store/%5F%5F11965%5F%5FOrangeRx%5FR610%5FSpektrum%5FDSM2%5F6Ch%5F2%5F4Ghz%5FReceiver%5Fw%5FSat%5FPort%5F.html) receiver works great and is super cheap. I use it with a Dx5e (http://www.robotmarketplace.com/products/0-SPM5500.html) remote in Phoenix.
-
only 10 bucks! :D
this works with all Spektrum remotes I assume?

I got 1000 bucks from one of my aunts. Planning to use at least some of it towards two antweights. Plans to surface sometime soon.

Rich aunt, favorite nephew, or inheritance?

Inheritance.

Oohh that sucks. Bad time of year.

Saving up cash ATM, planning to get a new laptop and parts for an AW.
Current plans:
(https://gametechmods.com/uploads/images/21926botmk0.1.PNG)
The two triangle thingies are weapon supports. The bar off to the side is the weapon (might be a bit small). Is this a good design for an AW?
Also I need name suggestions.
Also I renamed the team, because none of the pots are gonna have a reptile theme anymore and thought it would just be stupid.
also: Is it possible to modify lego wheels for use on a fingertech spark motor? I want to save money by not buying new wheels (also I think they are supposed to be grippy).
-

Interesting, how about the theme of the bots?
-
gaaah, stupid typo D:
-
Currently the antweights are ruled by either toughest wedge (antelope) or the biggest spinner (Gyroscopic). It's basically a all or nothing weightclass because everything has to be so light. Building an ant takes a different design mindset than building a 30, which is about as low that I would go if I was to build something similar to it.
Go on the builders db, you'll notice 3 things in common with almost all ants: large exposed wheels, they dot look like their larger counterparts, they have a proportionally larger weapon than most other weightclasses (be it wedge or spinner)
-
Hm. So a wedged VS wouldn't work? Bleh. I have other designs in my head anyway.
-

The general concept's fine, I think more the point was that you should look at the proportions/quirks of that style of bot to see what design issues pop up.
-
Oh, alright. What SKBT said just kinda confused me.
-
Alright, update time. After spending several years thinking of several designs, i've finally settled on one.
It will be an antweight with a Psychotron-like wedge. No weapon to save time/cash. Got another 150-ish dollars today because we had a birthday party. I'm gonna talk to my dad about it tomorrow, he's said in the past we can do it so I wil very likely have a working ant by the end of the year.
Are lego tires/wheels a good substitute for lite flites? I have so many at home that replacing them would be easier than having to buy so many sets of wheels. Also, what armor do you guys usually use on your ants?
-
I usually use cardboard....Also, if you're going to make a simple wedge, at least make sure to paint it or cover it in MLP stickers or do something to give it character.

Lego wheels will work, but why not use Lite Flites? They cost lest than five dollars a pair.
UHWM is common in the US, and HDPE in the UK. For dust covers, use 7075 or Chromemoly.
-
Don't worry Sparkey, I'm gonna paint it.
Ribbs, I want to save as much cash as possible toward motors, armor and radio equipment. If I turn up with an extra 10/20 bucks, I'll get lite flites.
What motors would you guys recommend? Fingertech Sparks?
-
Silver sparks. Gold sparks tend to strip pretty easily.
The big advantage to lite flites is that they are light.

If you want a decent radio at a good price, I would recommend this (http://www.hobbyking.com/hobbyking/store/__9042__Hobby_King_2_4Ghz_6Ch_Tx_Rx_V2_Mode_2_.html) radio. It does mix, and with the tiny esc's, it also will fail safe. You'll need a link cable (http://www.hobbyking.com/hobbyking/store/__9043__Hobby_King_2_4Ghz_6Ch_Tx_USB_Cable.html) to get it to work.
If you haven't picked out your ESCs yet, go with the Finger Tech tiny esc (http://www.robotmarketplace.com/products/0-FT-TINYESC-V2.html). You'll need two, but they are well worth the money. They also have a BEC built right in, so that will save you some money.
This Lipo (http://www.robotmarketplace.com/products/0-EFLB4303SJ.html) will give plenty of power, and this charger (http://www.robotmarketplace.com/products/0-GPMM3318.html) will work well with it too.
Yes, Finger Tec spark motors are the most preferred in ants. I use the 50:1 Gold Sparks (http://www.robotmarketplace.com/products/0-FT-SPARK16-50.html), but it would be better to go with the 33:1 Sliver Sparks (http://www.fingertechrobotics.com/proddetail.php?prod=ft-Sspark16)(For some reason, Robot Market Place does not carry the 33:1). Silver sparks have larger gear teeth, and can handle more punishment.
Lite Flites don't cost very much, please use them. A pair of 2" Lite Flites (http://www.robotmarketplace.com/products/0-DAV5520.html) cost lest than five dollars, and squish in a way that act as shocks. They can save your motors!
Lite Hubs (http://www.robotmarketplace.com/products/0-FT-LITE-HUBS.html) work great. If you want to get fancy, Dave's Hubs (http://www.robotmarketplace.com/products/0-DWH3MM.html) are the absolute best way to mount lite flites.
1/4" thick UHMW plastic sides (http://www.onlinemetals.com/merchant.cfm?pid=12550&step=4&showunits=inches&id=785&top_cat=181) will handle pretty much anything thrown at them, and is an easy material to work with.
1/16" thick 7075 aluminum (http://www.onlinemetals.com/merchant.cfm?pid=12659&step=4&showunits=inches&id=916&top_cat=60) is super light weight and very strong. Don't try to bend it.
That adds up to 176 US dollars. Add screws, and other mounting hardware, the total cost should be no more than 180-190 dollars.
-
You are awesome. I'll see what I can do.
-
Alright, the bot is a go. I'm going to be getting the design and parts list to my dad in the next hour, and the robot will be called Fire Arrow (or FireArrow, haven't decided yet). to go with that, the team will be renamed one more time to Team Ignition. I'll post the build report in a new thread in the proper section once we begin building.

Why do people even bother making pages when the bots don't even exist...
-
I got over-ambitious, OK?
-
Anyone know the basic dimensions for a standard AW wedge? My dad wants me to do a blueprint thing for it and I have no idea how big a regular AW is...
For reference, I want my bot to look like an AW Psychotron (http://battlebots.wikia.com/wiki/Psychotron).
-
the question is how small can you make your robot and still make it functional.
Take all of your components dimensions and create cutouts of the components and lay them out to figure out how small you can build the robot. Its kinda like RA2.
or you could do the same thing in a CAD program such as autodesk inventor or sketchup
MikeNCR's ant Kolabos was 5 1/2" wide at its wedge and it frame was 3 3/4"wide. Its length was 4 1/2". Height was 3/4"
-
So, the easiest thing is to get the parts first and then lay everything out? Ok, I'll tell him that.
-
Anyone have the dimensions for the reciever here?
http://www.hobbyking.com/hobbyking/store/__9042__Hobby_King_2_4Ghz_6Ch_Tx_Rx_V2_Mode_2_.html (http://www.hobbyking.com/hobbyking/store/__9042__Hobby_King_2_4Ghz_6Ch_Tx_Rx_V2_Mode_2_.html)
My dad still wants me to do the blueprint. Wants me to "learn something", whatever that means XD
naah, just get me the dimensions and I'll be happy.
-
They are 1 3/4" long by by 12 sixteenths of an inch wide and half an inch tall at the highest point with case. The antenna is about six inches long.

It came with my viper kit.

Can we see it please?

Looks like a solid concept. Make sure to doublecheck battery thickness vs. vertical space in the chassis, it's easy to miss by just a hair and have it mess with the whole internal layout.
I'd also suggest once you get the parts, cut out thin cardboard mock ups of the armor to do a final fit test before you cut metal. It's also not totally obvious how the armor fastens together while allowing battery removal, so that's something to think about while the parts are on the way.
-
If I could make one suggestion, it would be to swap the battery and the rx. That will put the heaviest part of the bot closer to the wheels, giving added traction.
-
Alright, I'll fix it up soon.
