Quick-change finger for robotic gripper

This invention is a system for quickly swapping out the fingers on a robot's gripper by hand. It uses a special lever on the finger that you turn to lock it into place on the robot's existing gripper. The patent claims focus on a very specific design for the robot's gripper, which has two arms, a cylindrical bar, and circular slots, and a locking mechanism that uses a small pin and a groove.

Why it matters: The 2010 filing predates the widespread adoption of collaborative robots and the demand for rapid retooling. Manual, quick-change end effectors are now more relevant for flexible manufacturing and human-robot interaction.

Status: ExpiredProtection ended and was never renewed
