Not all robots talk. It moves because the electromagnetic radio waves on the transmitter communicate with the receiver to move the servos.

Question

How do you make its wheels?

Community Answer

Wheels are another part of a robot. You can buy these in same way as other parts. Alternatively, you can make them from plastic, metal or wood by yourself using a machine that can cut through source material, for example CNC. Or, print them using 3D printers.

Yes, but it would be harder, because, just like adding the claw, you would need a lot more channels and mini motors.
