The most simple weapon is a spinning blade, that might cost 25 bucks, it just uses a blade from a saw and a servo and motor. You really dont need to worry about torque or anything like that, as long as its a sharp blade and it spins fast. The robot part will probably cost about $50-$100, unless you have radio recievers, transmitters, motors, servos and motor controller laying around the house.
I have some schematics and designs for an EMP generator. You could turn that on for 1/2 a second and the other robot would be dead Except you'd have to have 4 outlets running to it.
Blatantly this is your first robot. I strongly advise that you dont mess with saw blades.
