Hi everyone. This is my first post on the forums. I wanted to ask your expertise on a project I'm working on. I'm trying to design a setup where I rotate a ∏ shaped frame that has a 1kg load on the horizontal bar. The space between the frame should stay empty. The length of the side rods may be up to 1 meter, with the ability to slide the horizontal bar up and down. I need precise rotational motion so at first I thought lets go simple and attach a servo directly to the joint. Then I realized that the torque requirements would be tremendous at one meter away. I'm on a budget here so I don't want to spend too much on a servo unless I really have to. So what would be a setup that would minimize the torque requirements on the servo while keeping the precision? Timing belt and pulley? I'm not sure how this setup would work. The weight (horizontal bar) has to rotate from 0 to 90 degrees around the joint. It is important that the breaking between rotations, doesn't produce any bouncing. I'm also trying to keep the machining requirements minimal cause I don't have much else than a drill and a saw. Any ideas? Thanks!
