Abstract

This article describes a three-finger end-of-arm tool (EOAT) compliant device with textured fingers that grasp and hold an object similar to the way the human index and middle finger and thumb perform. Referring to the figures, Fig. 1 is a perspective view of compliant device 10 in open position surrounding an object 7. Fig. 2 is a perspective view of the device in closed position holding object 7. The index and middle finger of one textured finger are shown at 2. It is slipped on the left gripper plate 9L. The thumb textured finger 3 is shown slipped on the right or opposing gripper plate 9R. Fig. 3 is a detailed cross-section view of one of the textured fingers.

Three-Finger End-Of-Arm-Tooling Slip on Parallel Acting Gripper Strain Gauge Plate Compliant Device

This article describes a three-finger end-of-arm tool (EOAT) compliant device with textured fingers that grasp and hold an object similar to the way the human index and middle finger and thumb perform. Referring to the figures, Fig. 1 is a perspective view of compliant device 10 in open position surrounding an object 7. Fig. 2 is a perspective view of the device in closed position holding object 7. The index and middle finger of one textured finger are shown at 2. It is slipped on the left gripper plate 9L. The thumb textured finger 3 is shown slipped on the right or opposing gripper plate 9R. Fig. 3 is a detailed cross-section view of one of the textured fingers. A frame 8 is a slotted U-shaped channel and carries a backbone support 6, a polyfoam 4, a nylon covering 5, and a spring-loaded detent-ball 11 for positioning and securing each finger by means of slots 12 to the respective gripper strain gauge plates 9L and 9R. The closing of the parallel acting gripper plates with the textured fingers attached produces a conjoining of the tri-lateral surfaces of the textured fingers in a pincer-like envelope that complies to a great extent with the shape of the object 7. Strain gauges (not shown) are attached to the gripper plates 9L and 9R and receive the gram forces as the compliant device fingers grasp the object 7 and send these signals to a robotic controller indica...
