Title: Robotics Questions MEGATHREAD
Post by: MikeNCR on May 11, 2012, 01:17:27 PM
This thread exists for several purposes:

1: Robot history related questions.
2: Robot component and design related questions.
3: Discussion of answers to said questions given on this site or any other site.

Keep the discussions civil and don't get personal. There are a lot of experienced builders around that can answer questions and we likely disagree on many key points. Flamewars will be nuked from orbit.

Anyone can answer a question, and several people can answer the same question. For history questions, do try to make sure you're answering accurately. For design questions, there's likely no "right" answer and they will more often than not be an opinion based answer.

Ooh, this sounds interesting. I might ask the first question- who did Mortis get sold onto after Team Bud?

It's still in George Francis's possession- it underwent a major overhaul after being heavily damaged by 13 Black to restore it to full working order, but it doesn't fight anymore, instead being on display every now and again.

What happened to Wheely Big Cheese? :3
Quote from:  RW Wiki

The Extreme 1/Series 5 version of Wheely Big Cheese that produced the infamously huge flip, sending Axe Awe over the arena side wall from near the centre of the arena, went to Team Xbotz from Wrexham in North Wales and was completely rebuilt, with new electronics, batteries, revised pneumatics and upgraded drive system. It is still used in various live events and educational presentations around the UK.
In addition, the original Series 4 Wheely Big Cheese chassis was also owned by Team Xbotz, before being sold to, and fixed up by, Team Cylon (now Team Hydra), in 2008. Team Cylon have brought the robot out of retirement, planning to enter it into the Roaming Robots events. This raises the ather interesting possibility of both versions of Wheely Big Cheese actually fighting each other one day.

That's good- one, to know that it's going to a great team for the job of fixing both it and Rigor Mortis up, and two, the irony in how in the RW First World Championship, Mortis and Behemoth actually fought each other   :gawe:

WBC is in no state to fight at the moment, and is in the hands of Team Hydra, who aren't showing any signs of renovating it.

Mortis, was definitely in hands of Team Bud, and as with WBC, needs work doing to it. I think they did have plans of re-building it, but at the time their priorities were tied in Envy and Thor. They've recently bought Kan-Opener and have started building a new robot Full Tilt, so it seems likely that they may have sold it. Not too sure who to though, though seems logical that it would have gone to Kane Aston/Ant Pritchard.

What are the best combat robotics sites to refer to when looking for local competitions?  United States would be most important to me, but other countries would be good for other members.  Whenever I google search I get a ton of dead links and old expired crap.

UK:
fightingrobots.co.uk
robotwars101.org
roamingrobots.co.uk
robotslive.co.uk
robochallenge.co.uk

Obviously, I'm not so sure about the US, but I would have thought that the FRL is a good place to start.

I'm sorry but I don't really research what happened to robots that fought years ago... but typically what happens to a robot after it's retired is it gets gutted and parts end up in other creations or sold.

How does Dragon Con get away with such flagrant disregard for safety (no offense if anyone affiliated is reading this)?  In this clip, a spectator nearly gets brained by a vertical spinner tossing its opponent out of the arena (1:37)

Quote from: Dragon*Con rules
D. No vehicle may, under any circumstances, present a hazard to the judges, spectators, or the opposing operator(s). No vehicle may in its operation cause damage to anything other than the opposing robot or the combat surface. Any vehicle that imperils the viewing areas will be ruled ineligible for competition.

F. Judges may restrict any function deemed excessively hazardous

G. For sumo events, a minimum of 30' (thirty feet) distance must be maintained between the edge of the combat stage and the audience, for safety reasons.  No audience members are allowed within the safety zone, and children under the age of 16 are not allowed in the front row.

I guess my question is, why was that robot allowed to keep fighting unabated? 
Title: Re: Robotics Questions MEGATHREAD
Post by: SKBT on May 22, 2012, 06:56:52 PM
because that was an exhibition match between a 12lber and a 1lber. After that happened they added

Quote
Vehicles may not compete out of weight class, due to safety considerations.


to their rules...

I can answer the latter, the answer is yes.  It's no longer competitive but still well-upkept.  Ian Watts is an engineering professor at the University of Brighton.  In his course, the final project is to build a featherweight robot, and a tournament is held.  After the winner is crowned, Ian wheels in Bigger Brother and smashes up all of his students' bots.  Check it out (skip to 26 minutes for Bigger Brother):

God this is like skype all over again. I'll just list off whatever I can remember and you can judge for yourself

-There was another robot supposed to be in the Middleweight Final of Series 7. It was called Voodoo Child and made by the same guy who created Broadsword. However it never competed due to hideous exposed wiring and looking even more flimsy than it's predecessor. I don't think it even got through the door.
-Jayne Middlemiss made my sister cry. Purely because she wasn't Phillipa Forrester. Me and my father were happy talking to her, but my sister wasn't for some reason. Even though she had done the whole interview thing a year earlier for Extreme 2. I remember her saying to my father "I'm sorry! I'm making your children cry!". This is also probably the reason there are no pre-battle interviews for that match.
-The Typhoon guys were very nice. Contrary to popular opinion.
-The TAN guys were very nice aswell. So I might be slightly skewed when I say it's one of my favourite robots.
-In the pits, over the 2 times we were there, we were stationed near; Pussycat, Typhoon, Barborous 2 'n' a bit, Thermidor 2, Behemoth, TAN and possibly Dantomkia.
-Those remote control booths were like sodding ovens.
-I remember being smug because Phoenix (our second robot) was shaped in such a way Growler couldn't bite it. So instead it nearly got launched out by the floor flipper.
-At qualifying (Yes a middleweight bot had to do that, I think my father may have been trying to pass it off as a underweight heavy though.) I remember we faced a robot that was not dissimilar to Series 3 robot Armour Geddon. (http://robotwars.wikia.com/wiki/Armour_Geddon) I also remember seeing Shove and thinking it was the new house robot to be announced next series. And seeing The Mouse on a static display and wondering what the heck it was. I got to sit next to TerrorHurtz though and that was very cool.

I'll edit in stuff if I remember anymore. Please note this is from years ago so my memory is a bit rusty.

It was similar in design to Wheelosaurus and had little armour evidently. Unless he was going to put some on after.

Malc ran off of 2 wheelchair motors and the spikes were static. So they would never "Work" like Jonathan Pearce said they would. Phoenix ran off of EV warriors and the lifter actually worked! Shame we never got a proper chance to use it though. We had severe control issues with Phoenix. It was damn near undriveable. That's about it, really. They weren't that interesting.

I see:
Don't bother with Copals, they have plastic gears. I suggest the Finger Tech Sliver Spark motor. http://www.robotmarketplace.com/products/0-FT-SSPARK-50.html (http://www.robotmarketplace.com/products/0-FT-SSPARK-50.html), I have the Gold spark motor, and it works great. Sliver Sparks have bigger teeth, reducing the chance of striping.

Don't bother with the mounts, they won't fit the sparks, even if they did, you would have to bond the mounts with a lexan surface. If you really want a mount, use a finger tech mount.http://www.fingertechrobotics.com/proddetail.php?prod=ft-bearing-block (http://www.fingertechrobotics.com/proddetail.php?prod=ft-bearing-block). It comes with a ball bearing pressed in, so it won't cause to much strain on the motor shaft.

The wheels are fine.

Dave's hubs are fancy indeed, but the Finger Tech hubs(http://www.robotmarketplace.com/products/0-FT-LITE-HUBS.html (http://www.robotmarketplace.com/products/0-FT-LITE-HUBS.html)) will work just as well.

Avoid Tactic products. Use a Spektrum Dx5e(http://www.robotmarketplace.com/products/0-SPM5500.html (http://www.robotmarketplace.com/products/0-SPM5500.html)) with the Hobby King Orange rx(http://www.hobbyking.com/hobbyking/store/__11965__OrangeRx_R610_Spektrum_DSM2_6Ch_2_4Ghz_Receiver_w_Sat_Port_.html (http://www.hobbyking.com/hobbyking/store/__11965__OrangeRx_R610_Spektrum_DSM2_6Ch_2_4Ghz_Receiver_w_Sat_Port_.html)). Costs less than that Tactic system, and will work far better.

That ESC is nice, but the Finger Tech Tiny ESC(http://www.fingertechrobotics.com/proddetail.php?prod=ft-tinyESCv2 (http://www.fingertechrobotics.com/proddetail.php?prod=ft-tinyESCv2)) is better. It works great, and are way lighter than the Saber tooth.

That battery is WAY over kill, that's a huge chunk of your allowed weight. A smaller battery(http://www.hobbyking.com/hobbyking/store/__18204__Turnigy_nano_tech_850mAh_4S_45_90C_Lipo_Pack.html (http://www.hobbyking.com/hobbyking/store/__18204__Turnigy_nano_tech_850mAh_4S_45_90C_Lipo_Pack.html)) would be much better here.

You haven't selected a charger. I'd recommend the Turnigy Accucel-6 50 watt(http://www.hobbyking.com/hobbyking/store/__7028__Turnigy_Accucel_6_50W_6A_Balancer_Charger_w_accessories.html (http://www.hobbyking.com/hobbyking/store/__7028__Turnigy_Accucel_6_50W_6A_Balancer_Charger_w_accessories.html)).

1/16 thick aluminum is way too thin, go with 1/4 thick UMHW plastic(http://www.onlinemetals.com/merchant.cfm?pid=12550&step=4&showunits=inches&id=785&top_cat=181 (http://www.onlinemetals.com/merchant.cfm?pid=12550&step=4&showunits=inches&id=785&top_cat=181)), easy to work with, super strong, and light weight.

1/8 Grade five titanium heat treated would work wonders for a good spinner killer plow. Check Titanium Joe(http://www.titaniumjoe.com/6al4v%20sheet.htm (http://www.titaniumjoe.com/6al4v%20sheet.htm))!

A good way to mount your stuff is high strength Velcro, of the highest quality.


Hope that helps you a little.

This helped a LOT, but I still have some questions:
-Can I get the titanium pre-bent and cut to size? Depends, but it be easier to cut it your self.
-How would I cut UMHW plastic? Also, how would I put all the armor pieces together? You can cut it an ordinary hacksaw. You can put it together with Plastite screws (http://www.fastenal.com/web/products/detail.ex?sku=0142886), they're made just for plastics. In a pinch, though, wood screws will work also.
-Aren't Hobbyking parts poorly made? Luck of the draw. The Orange RX are used by many users here, and Turnigy products are at least decent.
-Where would I buy the Velcro? Any hardware store will have it. Super high strength can be found online (https://gametechmods.com/forums/www.homedepot.com/buy/velcro-industrial-strength-15-ft-x-2-in-tape-90198.html#.UKB1WYawV7k).

Also, some other notes:
-I had no idea copals used plastic gears, this info helped a lot.
-That tiny esc looks hard to work with, I wanted the sabertooth because it seems easy to use and there's a bunch of tutorial stuff for it at the robot marketplace. All the Tiny Esc needs is a little soldering work to use. They don't need any thing else, you can adjust them with the calibration if needed. The mixing can be done with either with the transmitter or the through a stand alone mixer (http://www.hobbyking.com/hobbyking/store/__6321__TURNIGY_V_Tail_Mixer_Ultra_small.html)(Required if you want to use a gyro.)

sabertooths suck don't use them.

hobbyking radio gear is badass.

850mah is way too big. you need 300mah. tops

1/8" ti is like 220 armor thick. you could do 1/32" and be fine.

also your shape is stupid. try a more conventional wedge shape and see how that looks.

you can buy velco at walmart

you can bend 1/16" ti with a pair of plyers and a blowtorch. just heat up till orange and bend.

you can make it smaller. if you can make it smaller is better because you can go thicker on the armor. you can use nutstrip for anything.

i don't like your plow because it will be a pain in the butt to make and attach. if you were to attach it you could probably have an internal vertical 1/2" thick uhmw wall and attach it with a pair of .25" lag screws. I'd personally go with a generic wedge instead of the plow shape.

yeah, i went to bot blast last year safety c started at 9ish on the day of the event.

for safety c you want to have a way to have your wheels off the ground, a power disconnect and if you have a weapon a way to disable it. it also must stop moving if radio contact if is lost.

One last question:

Are Dave's hubs supposed to stick to the lite flite axle? Because only one out of four of mine does that and I was thinking of getting some lite hubs instead, they seem easier to work with.
Title: Re: Robotics Questions MEGATHREAD
Post by: SKBT on May 22, 2013, 12:15:05 PM
dave hubs + lite flites mount like a car tire to a rim. you take the plastic hub out of the lite flite to correctly mount to dave hubs. if they still don't quite fit try using a CA glue to secure them to the hub. (it is a total pain in the ass to get them off though).

I knew that (in fact I already have all the hubs assembled) and I kinda thought that's what you had to do to get them to stay on.

Plus, if it's a pain in the ass to get them off, then it'll be a pain in the ass for the opponent too :3

m4 is tiny and metric so i don't recommend it because they are slightly harder to find.

getting small damaged bolts or screws out of a robot is a pain.



i don't go smaller than 10-32 machine screws for metal or #10 woodscrews for uhmw. also you are much less likely to break a 10-32 tap than a m4 tap.

What kind of steel did Mike use on Kobalos?


I used 3/32" thick unhardened 4130 steel, which was massive, massive overkill. Something in the range of 1/16" Ti or steel should be plenty. 3/32" will let you countersink larger screws, which is nice. I actually had to round off the top of the 4-40 flatheads on Algos to keep from having the flatheads catch on other bots as they go up the wedge.


This gives the cleanest shot of the wedge on Kobalos- https://gametechmods.com/uploads/images/77206KobalosPowered.jpg (https://gametechmods.com/uploads/images/77206KobalosPowered.jpg)


This is how I'm doing the wedges now- http://www.instructables.com/id/One-Pound-Fighting-Robot-Algos/step4/Assembly/ (http://www.instructables.com/id/One-Pound-Fighting-Robot-Algos/step4/Assembly/) and http://www.instructables.com/id/One-Pound-Fighting-Robot-Algos/step5/Shaft-Replacement-and-Hardening/ (http://www.instructables.com/id/One-Pound-Fighting-Robot-Algos/step5/Shaft-Replacement-and-Hardening/) (The latter shows the rounded flat heads)


I've become a big fan of using Nutstrip for this sort of thing, as it means you can quickly replace it if it gets damaged and you're only having to work with flat parts unless you want to complicate things, so part fabrication can go much quicker.

Quote
Each shaft was heated to a bright orange using a torch then dropped lengthwise into the oil bath. After cleaning off the shafts I did a quick test hit on a spare piece to see how hard the shaft had gotten relative to an annealed piece of O1. The annealed piece bent 90 degrees, the hardened piece snapped off very cleanly. The second stage of the process was tempering. The three shafts and test piece were placed in an oven at somewhere between 450 and 500 degrees F and left to soak for 45 minutes.

Since then, I've gotten better at the initial hardening and have to take them up to 800-900F to get the proper hardness after tempering.

That depends on your location.
The cheapest way would probably be a feather weight wedge. I would recommend:
Drive: A pair of Robochallenge 12volt drill motors. I'm not from the UK, but this seems to be the most popular drive motor.
Wheels: Again, Robochallenge wheels, which are pre-made with the threads required.
ESC: A pair of BotBitz 85amp EScheaps. If you're feeling daring, you could hack the ESCs your self, but it's risky.
Radio: Hobbyking HK-T6A. Decent radio, but I would recommend the link cable to add mixing and the likes.
Battery: A pair of 7.2volt NIMH sticks. Lithium batteries are preferred, but they burst into flame if miss handled
Charger: Turnigy ACCUCELL-6. Needs a power supply, but you can use a computer supply if crafty.

personally, i wouldn't use slot aluminum and t-nuts for a frame. too much potential to shift and for stuff to slide out.

that charger sucks. i had one and it charges way too slowly for my liking.

i love the vextrollers. i should have run them in robo-rooter at botblast.


the fingertech viper kit is similar with differences being they give you tinyesc's, set it up to run off a 9v battery and have a pre-built frame that may or may not be useful depending on what you want to do.

kitbots.com has some nice 3lb kits. the "weta" kits consistently win events.

in a 30lb wedge, i would run at 5s lipo or 18v nimh and 4" or 5" wheels with 4 drill motor drive. anything less will be slow for a wedge.

Drill motor drive is always a good starting point but if you want to spend a bit more money get some gimson GR02's, botbitz85's have been proven to be good esc's for the price and be able to stand up to most things thrown at them, I can't vouch for the charger ribbs suggested but I have an Imax B6 to charge the lipo in minor tom but it can also do nihms, battery wise 12v will run the drills fine but if you want a but more punch to your motors you can go 18v which does make them run faster but increase the likelihood of stripping gears. HDPE is a good material to work with, it's easy to work, relatively cheap and quite tough if you get it thick enough. If you plan on going to the champs though wear resistant steel like hardox is the armour of choice there because of the spinners.

4130 or 4140. robo-rooter's disk is .25" 4140. if i was designing an disk or bar antweight i'd do .125" thick 4140. if i was doing a drum, i'd do something like the kitbots beater with 3/8" 7075 and 10-24 capscrew teeth.

also its cheaper to build 3lb robots

it costs $40 for two 1000rpm motors and two vextrollers  vs the $110 for two tinyesc's and sparks

Fairyweight = 150g

Beetleweight = 3lb
Mantis = 6lb (Not widely used tbh, i wouldn't make one as a first bot)
Hobbyweight = 12lb
Featherweight = 30lb
Lightweight = 60lb
Middleweight = 120lb
Heavyweight = 220lb
Super Heavyweight = 340lb (No longer an active weight class)


There's also a 15lb class for BotsIQ, which lots of schools do.

A good 4WD beetleweight wedge, minus materials, would probably run you about 150 dollars, and that's mostly radio equipment. Antweights are more expensive mainly because silver sparks are more expensive than 1000rpm motors.

I'll leave Alex to do the full list, I'm kinda tired atm. :3

Alternate wheel option: http://www.fingertechrobotics.com/proddetail.php?prod=snap-wheels (http://www.fingertechrobotics.com/proddetail.php?prod=snap-wheels)

Saves having to buy the snap hubs and lite flites then tearing the lite flites apart to put them on the snap hubs. If you go with the 1000rpm motors, get the 4mm bore snap hub, if you go sparks, 3mm snap hub. If you go beetle, 2 sparks is going to be very close to the lower limit as a workable drive. You'd be better off with 4 sparks if you want to use silver sparks for drive.

FIRST does task-based robot events.  Their founder doesn't like violence, or even the concept of winners and losers, so that should give you a sense of how likely it is that a FIRST event will involve combat.  I would assume that Warhead still resides in the garage of Ian Lewis or Simon Scott.

Why aren't there more black guys in robot combat? Like the only guys I've seen is the dude with dreads in the Demolisher team and one dude in Robotica who had this cool ass bot that got beaten in the fight to the finish. Like wtf man, is this sh** like hockey or something?

Without getting too political, it requires a large amount of disposable income.

Not really; it's Pennsylvania so it's a bit of a trek for them.  That's some devotion.

I've wondered the same thing.  I think it has more to do with cultural differences.  Robotics is a geek hobby and, at least as far as I can tell, there aren't as many black geeks in general.  Like if you go into a game/comic store, it's mostly white people in there too.

It used to be that there weren't very many women geeks either and so there weren't very many women in robot combat.  But now that it's more "in" to be a woman and a geek, you see a bit more representation in the new Battlebots.  Still male-dominated but it's better than it was.  Blacks will get there eventually too, I expect.

. In thinking about it, I remeber seeing a a preview for last season's Battlebots, which showed the Giant Nut being hoisted by a pair of white hands, and realizing that that didn't spoil anything.  One could argue that they were masculine looking, which ruled out Sweet Revenge, Chomp, and Plan X, but I don't think that would be much of a spoiler.

or the backing of an organization, such as MIT

which might as well be the same thing

I spoke with Grant about Satans Mutt at the Featherweight champs last year, it uses a custom made valve that needs maintenance, however they don't have the time to fix it up so it's used exclusively as a display piece at their live events

i'm seeing more and more robots nowadays with spinners that only have one tooth, as opposed to two, three, or a more traditional number. i understand why they're doing this, but i'm wondering how. how do you figure out the way to make a disk/bar/spinning weapon bigger on one side and still be balanced?
Title: Re: Robotics Questions MEGATHREAD
Post by: Badnik96 on May 25, 2017, 12:45:22 AM
most CAD softwares include a feature that can calculate the center of mass of an object, which you can use to create the hole for a weapon shaft on any object.

most people just get theirs cut/machined for them using cnc machines or laser cutters

The free emachineshop software has some nice 2D CAD tools with easy centre of mass calcs.
Most of the single tooth designs I've known of or have been involved with have been done in that software, including the Neutron disc and new Apex bar.

A lot. At minimum, you're looking at 1000 bucks to build a basic platform, and at least 5000 to get it competent.

Here's a robot with offset drive wheels.
Is there much difference between turning clockwise and turning anticlockwise in terms of spinning speed or wear on the tyres?
If so, which direction does what in the above setup?

The basics on the whole have not changed much. Components and methods have more-so. The discussions of brushed vs. brushless motors and how specifically to construct a robot are generally lost on someone without the understanding of robots and engineering that it provides. It taught me everything I needed to know in about 2016 to get me started, and know the questions to ask to get myself up to speed.

I admit I'm a bit out of touch with robots these days, is brushless the default now or something?

brushless is the new hotness but brushed is the more simple option especially at the insect level.

Anyone know any good motors for a Hobbyweight? Specifically, I'm hoping to build a Maximus-style fast (as in, whatever the equivalent to 30mph would be for a Hobby) brick wedge with a lot of torque.

On that note, anyone know of a good way to have a good deal of torque w/o losing much (if any) speed? My idea was to take the motor, attach a belt/gear/chain with a really low/high ratio, then attach to that one with a really high/low ratio to even things out; on a scale of 1-10 how dumb an idea is this (1 being Galaxy Brain, 10 being critical derpface)
Title: Re: Robotics Questions MEGATHREAD
Post by: Somebody on August 20, 2019, 09:13:07 PM
It would probably be lighter just to find a motor appropriately oversized to deliver both speed and torque. As for motors, if you want peak power, big brushless inrunners are probably where it's at. Just need to get the gearing right.

Also be careful testing because spicy drive becomes on-fire drive pretty easily.
Title: Re: Robotics Questions MEGATHREAD
Post by: Scorpio on August 21, 2019, 09:39:30 PM
New question: does anyone know the average speed, approximately, of a hobbyweight, so my bot can surpass that?

ONE MONTH LATER EDIT: So I did some research into brushless inrunners, and came across some on Hobby King. Think four of them will be enough for what I'm looking for?
