Re: Mechanical going Electric

Edit:
To make that tank unit into something RC you'll need:
2 motors and the 2-motor transmission like you said
Battery pack(s) and charger
2 motor controllers
A radio system, maybe 3 or 4 channels so you could add functionality to the chassis other than driving. Pay attention to the actual control input on the remote and make sure it's how you want to control tank-steer.
Misc wires/cables/switches/velcro

When it's all said and done you'll have put a reasonable bit of $$ into a $15 chassis, you may want to think about getting a larger, more capable chassis.


A buddy of mine, AndyA on CD, and I used to make IFI-powered RC cars.

A victor 883 can handle 24 volts IIRC and can be controlled with a regular hobby RC remote. We coupled a victor 883 with two high-capacity 7.2V RC racing packs wired in series and used those to power a 14.4V companion drill motor. Buying RC stuff second hand from ebay kept costs low. The wiring is very similar to a FIRST robot because you have a PWM signal running to a motor controller that has batteries on one side and a motor on the other, there's just one motor instead of 4, 6, or whatever. It was a very fun hobby and you'll learn a lot, like how a Victor can handle flat-out power for 20-30 minutes without a fan and be fine.

Just a thought.
