Electromagnet question...?

Question

I am creating a battlebot, and I want to create a device that disables the opponents electrical circuit, or blocks the signals (RC remote). It should be simple.

Answer 1

RF jambing is relatively easy, unfortunately the same wide band saturation signal would disable your battlebot as well. You would need to operate you vehicle with IR, fiberoptic or some other form of communication that was immune to RF transmission for the plan to be effective.  While you could construct a selective band-pass modulator you would 1st need to know what channel each competitor was using.

Answer 2

The easiest way to do that without damaging your own bot would be to attatch something similar to a stun gun to your bot and have it fire it at the other bot. This would almost surely fry every circuit. Just make sure you aim for metal and nothing plastic. Not sure if you can attain one without a permit though.
