Not sure what to ask for here, maybe which motor and other tech parts I'd need, but here's the idea. I just want to make a stick figure (probably pvc) bend forward, delay a moment, then go back to upright, delay a moment, and repeat. I'm not expecting it to weigh much - empty frame, wig head, clothes and hands. Is there a way to vary the angle from prop to prop if I make more than one (15, 45, 90 degrees)? Is there a name for this kind of prop? Anything else to add?

Thanks in advance!
