Abstract

This article describes a crash-avoidance gripper in a robotic device which eliminates or minimizes costly damage to the robot and/or tooling. Robots are involved in handling and moving parts, tools or both. Any misalignment of parts in the fixture could be cause for the gripper, with another part or tool in its grasp, to collide with a protruding part. When a robot traverses in a horizontal motion to its position, any unplanned obstruction in its path could result in a costly crash of parts, tools or both. Frequently the gripper fingers are designed to totally encase or firmly grasp the part or tool, making it virtually impossible to dislodge the part or tool during a collision. The crash-avoidance gripper disclosed herein avoids or limits this probability. Fig.
