battle bots
« on: September 19, 2012, 07:29:09 PM »
i have competed in battlebots a bunch of times and i think that i am going to get back into it, i am going to bring my bot into the lab and let everyone see.

in the size that there are arenas for they only cost  100-200 to get one running. and they usually do not need to be replaced every time you fight. the hobby shop that puts on the fights is in bradington and is called robotmarketplace. they put on 3-4 fights a year.

http://www.robotmarketplace.com/products/GCRS.html

i want to design one that can be 3d printed that way if i break somthing i can just print another. also the laser cutter will help me make some more complicated designs.

i am just putting this out there to see if there is anyone else interested in making one.

This sounds awesome. I don't know the first thing about building one, but would be happy to learn. :)

that is the exact reason that i got into it. you dont have to know anything to make it work. the only thing that you have to do is make sure that you dont exceed your weight class. 150gram, 1lb, 3lb . and thats it.

i learned most by competing. what works and what doesnt. i did luck out with my bot that i bought some really amazing gear motors that are just tanks. the trouble is that they take up 50% of my 1lb weight. so trying to make a chassis that is both strong and light was my challenge.

if i wanted to add a weapon to mine i would have to start over with a new design using lighter motors. there is just no more weight that i can shave without a total redesign. but that is the great thing. you can have just a simple push bot and still win.

i just like the ability to make new things and design from the ground up, using things that i already have. with rc cars, trucks, planes, helis. you go by there plans and that is it. you can add accessories but it is still there main design.

i did bring in my bots last night and they are in my locker if anyone wants to see them.

Someone sugjested that I do a workshop on battle bots. So I have been working on seeing just how cheap I could make a battle bot. So far chassis built from scraps motors under 10 for two. We can build the wheels, remote control  hobby king 20$, battery we can scrounge batterys from all kinds of stuff but if we had to buy it would be in tye 5$ range,the problem comes from the speed control. Pololu has motor controls but they require a micro controller, does anyone know a way to sync them up to a rc car remote or a source for a dual motor cheap speed control. If I can find one for 20$ then I could get it down to around 55-65$ plus shipping and tax. And I am planning on making a couple designs of bots to get a starting point.

Any help with the speed controls would be great. They only need to hold 1-5 amps and can run on anything from 3-11 volts

Thanks

So, modding up an old thread; back in the day, I used to do Critter Crunch (20 lbs / 12inch).  What size bots are we talking about here?

Per JD's suggestion, we'd plan to ask them to do a match at Maker Faire this year :)

Oh, it's fun!  They've tamed it down a good deal from the original rules, though.  My question was really about what weight classes we were considering, before I go looking in my junk box...
