Rear-mounted gimbal for supporting test head

摘要

A manipulator for supporting heavy as well as lighter test heads in a small footprint includes a body and an interface for supporting a test head from behind. The interface includes a first portion fixedly attached to the body and a second portion fixedly attached to the rear of the test head. The first and second portions of the interface are rotatably coupled together to allow rotation of the test head about its approximate center of mass. Although the weight of the test head is entirely borne from the rear, the test head can still be moved with relatively little applied force, thereby satisfying the requirements for compliant docking.
