cool
BTW why did you need to hack the receiver?

I don't see a main battery, which I believe is required on a FRC robot...

Well actually since it has a modified radio...it's illegal.

<R61> The control system is provided to allow wireless control of the robots. The Operator Interface, Robot
Controller, Speed Controllers, Relay Modules, Radio Modems, Batteries, Battery Charger, AC Adapter, and
9-pin cables may not be tampered with, modified, or adjusted in any way, (tampering includes drilling,
cutting, machining, gluing, rewiring, etc.) with the following exceptions:
• The dip switches on the Operator Interface may be set as appropriate.
• The user programmable code in the Robot Controller may be customized.

• The Speed Controllers may be calibrated as described in owner's manuals.
• The fuse on the Spike relay for the Air Compressor may be replaced with a 20 Amp Snap-Action circuit
breaker.

Wow, they actually PAY you to come up with this stuff? Money obviously well spent.

OK, John. It's tiny. Probably not much use on defense. May not take many hits from a Poof-ball to disable it. Needs a team number, an LED, and a flag holder. Will probably be crushed by your alliance partner about 2 seconds into autonomous.

But it seems like it runs, and would appear to be very maneuverable. Assuming it survives, can you find a way to score with it?

Your strategy may be to climb the ramp early and hope an opponent doesn't decide to scoop it up and toss it into the center goal.

Is that the 2006 placebo? What kind of penalties are given when you crush it into the carpet?

I think it's obvious it wouldn't pass inspection. But it brings up an interesting point. Just how small could a bot be and still pass inspection? I think it would be cool if the game rewarded space efficiency. Like you can still use dimensions 28x38x60, but you can fit in 28x38x45 you can use additional air tanks or additional motors.

Back in i think 2003 a team made an emergency bot that was donated to teams at their competitions for matches they couldn't bring their bot out for and it was pretty much a 12 inch cube that had everything it needed self contained.

How does the lil thing move? What supplies the RC with power? I don't see any motors (perhaps under the RC). I see pwm pins being used, are there 2 victors under that bot?

It uses Vex/Edubot motors, which, much like servos, are powered by the RC's backup battery.

How do you turn it on/off with no main battery? My guess would be touching a nine volt to the main terminals to start it, and using reset to shut it off...
