An example test head manipulator includes a tower having a base and a track, where the track is vertical relative to the base, and arms to enable support for the test head. The arms are connected to the track to move the test head vertically relative to the tower, and the arms are configured to control rotation of the test head. Each of the arms includes a cam that is rotatable, and at least one plunger in contact with the cam and that is configured to contact the test head. Rotation of the cam is controllable to move the at least one plunger to offset an uncontrolled rotation the test head.
