Im supposed 2 design a robo like this 1, but here, the mechanical part seems more tought thn the electrical and programming. I couldn’t make out what mechanical structure is being used to have this type of motion. Can anyone plz help. Here’s a start: There r 2 motors attached in the centre part of the robot, which keeps sliding back anf forth. But, I can’t figure out out is the motor shaft being coupled to the structure, and how does it have tht kinda motion.
