Patent number: 5909941Abstract: The present invention relates to a passive multiple remote center compliance (MRCC) device that serves as a mechanical wrist for a robot arm. Such a multiple remote center compliance device comprises a translational structure and a gyrational structure serially interconnected between an operator member and a mounting member for enabling translational and rotational motion at, near or beyond the remote compliance center, that is, the functioning end of the operator member. The translational structure is securely connected to the mounting member (such as the end effector of a robot arm) and is provided with a translational block therein so as to furnish lateral compliance and orientational compliance. The gyrational structure is connected and operated by an operating member (such as the gripper of the robot arm) and moves relatively to the translational structure.Type: GrantFiled: September 16, 1997Date of Patent: June 8, 1999Assignee: National Science CouncilInventors: Chi-Cheng Cheng, Gin-Shan Chen
