Seeking mechanical design help for an outdoor mech 'robot' build!
I am currently collecting car parts and I'm itching to make a mech robot (like these: https://www.pinterest.com/finechen39/painted-robot/)
What I really want to do is have it close to my garage door, inert and crouching, until a motion sensor picks up movement. Ideally three actions would follow: I'd like it to stand up, ideally with lights turning on, and shortly afterward crouch back down.
I have a shop and can weld, woodwork and have a very basic electronics understanding. I think I'd like to learn about hydraulics (I was looking into a used motorcycle lift as an internal mechanism to get this thing to rise). I'm not sure yet how to set a delay before it crouches back down.
I'm looking for any recommendations - this is the first phase of my research into this project!!!
OK, thanks in advance!
