I have a 3DOF platform that I'm trying to make more stable. It's difficult to explain in words what the issue is so I've added a GIF below.
Any ideas of how I can get rid of this wobble? The DOF arm tends to cave inwards. I know it's being caused by the very small gap between the screw and the channel but is there any way to prevent this? Since the servo's I'm using don't have a dual shaft going through and through I can't modify the servo arm to be a inverted-U attached on both ends of the servo.
