There’s an event in the "science Olympiad" called sumo bots and it requires that i build a remote operated robot that can push another robot out of a ring. What kit would allow me to do so or a robot building kit which i could customize to do so?
VEX is always a good idea for these robot events. It’s easy to use and pretty efficient, but it’s not the best kind of kit out there because the motors are quite weak. But, as far as kit’s go, your best shot is with VEX. The next best is to salvage motors off of toys and somehow attach them to a frame, but that’s obviously harder. Seriously though, most of the people at states and nats will be using VEX with some other parts added in.
