Abstract

The multi-tasking robotic gripper 10 (Fig. 1) can be used when parts of various sizes need to be transported as part of an automated robotic assembly line. The gripper is composed of two parts: a tactile finger assembly 12 and a dual, independent vacuum head assembly 14 which is mounted underneath the tactile finger assembly 12. The tactile finger assembly 12 consists of two opposed fingers 16 which are controlled by parallel linkage arms 18 for precise gripping. Referring to Fig. 2, the dual vacuum head assembly 14 consists of a center vacuum pencil 20 which is spring compliant and retractable within the housing 22. It may either be extended down below the tactile fingers or retracted up out of the way for complete finger closure.
