For pyramid climbing: I'm considering a way to rotate our robot upwards off the ground by clamping onto the horizontal bar and swinging our robot body up, like this poorly drawn diagram.
Two questions:
1) What kind of clamp would be able to stay in place without slipping? Is it COTS or can we build it ourselves?
2) Is there a way we could make the clamp not require motorization (because motors are heavy and draw power)? For the motor that would be rotating our robot body upwards, would a window motor work on its own? Would two? Or would we have to have some intense gearing? We expect our robot will be around 100 pounds at the very least, weight is always an issue with our team.
