Robotic Gripper With Force Control And Optical Sensors

Abstract

Robotic gripper locates, measures, recognizes and manipulates objects in assembly-line setting. Fiber-optic sensors in fingertips help locate and identify object. Gripper grasps object and determines size from finger-position feedback, while grasped under force control. Prototype handles geranium cuttings in commercial greenhouse, basic concept and design modified for other objects (rods or nuts), including sorting to size.
