 The robotics manipulator used for our research is a commercial
robotics manipulator from Rhino Robots Inc. It is a XR-4 arm driven by
a Mark IV controller. The XR-4 are 5 axis revolute corrdinate robot
arms with a motor driven gripper. It can be extended up to 22.5 inches
and lift weight up to 4.0 lbs. 
<p>

  All its axes are controlled by DC servo motors using incremental
optical encoders for feedback and contain limit switches which are
used to position the arm to a hardware (known) home position
