Applicant: Genmark Automation,USA Patent number: US6,297,611Publication date: 2 October 2001Title: Robot having independent end effector linkage motion

The invention relates to systems using robots to transport substrates between different locations. The system comprises a robotic arm and a frame. The robotic arm comprises an end effector linkage mounted to an extensible linkage. Each of the linkages can be actuated independently using an associated motor, with the extensible linkage serving to convey the end effector linkage to the vicinity of a target processing station for delivery or retrieval of a substrate. Motion of the linkages may be synchronised to reduce travel time, and multiple end effectors may be mounted to the extensible linkage for increasing throughput.
