Simple robot to build, involve no pcb or proto board, no frames, just using a lot of glues.

The idea is to create a functional Droideka from Star Wars, or at least something as close to it as possible!

I'm trying to build a four legged walking Robot that is inspired by the Boston Dynamics Spot Mini and James Bruton's OpenDog.

Hi. Have you checked the photodiodes polarity? They should connected in reverse biased manner. The cathodes should connect to 5v and the anodes should connect to resistors/analog arduino pins. I think I messed up on the circuit scheme.
Simply by measuring & comparing light intensity from each corners (front-left, front-right, back-left, back-right) using 4 photodiodes.
Thank you. I really appreciate your suggestion. I didn't know about printer's micro switches before.
