The Astrobotic team at Carnegie Mellon University brought a new computer-controlled robot arm into operation this week by loading up CAD files of the camera unit that will ride atop the mast at the rover's center. The arm carved away foam to create a mold to be used for carbon composite layups to create the framework that will hold two wide-field HD cameras for 3D imagery plus a telephoto zoom HD camera. In the photo, the mold is approximately 18 inches long and five inches tall.
