I'm trying to rotate a lever link to gently "offload" a load using a servo. Here's a drawing:
Here, the red is a lever, yellow pivot and black is the load. To offload, the lever needs to be turned 90 degrees. I know I could simply put a servo where the yellow pivot is, but the problem is that the servo may not have enough torque to hold the load. The load is typically around 1-2kg and the distance from the pivot is around 15cm. The servo has a stall torque of around 10kg-cm.
Is it a good idea to drive a cable on the right hand side of the lever with a servo? Or is there a link setup that allows such a small servo to drive this lever?
