Re: Roller Claw

Our roller claw used Delrin pulleys that we turned on a lathe and rubber O-rings on both the drive pulleys and for the the main contact surface of the gripper. We keyed the delrin pulleys mounted on the motor shafts, used 3/8" hex-shafts and 3/8" bearings and broached the rollers that were on the driven end of the gripper, and used simple round shafts on the front end of our gripper. If I had a picture of the whole assembly, I would attach it. It worked fairly well for the most part; however, eventually the O-rings began to wear and had to be replaced.
