The software on the robot side is coded using C. Robots will never replace humans in the desperate effort to save others , says retired Army Lt. Col. John Blitch , director of the newly formed Center for Robot Assisted Search and Rescue , who rushed to New York from Washington with several robots to see if they could be of any help . The value of an autonomous wheelchair for severely disabled patients seems clear , but robotics engineer Neil Schubert , who works on the company 's health and safety products , said that safety requirements set a very high bar for robots meant to transport humans . Greater variety also results from attempts to describe natural objects in outdoor scenes , which can be far more difficult to encompass with formal description techniques than the man-made objects that robots normally act upon . Almost all robots , including current walking robots , embody a " stiffer is better " design and control philosophy inherited from the earliest days of numerically controlled machine tools , where position accuracy in the face of unpredictable force disturbances was of paramount importance . This section has argued that it is both useful and plausible for robots to represent shape data at multiple levels of detail . The client uses Sensor data including distances between the robot and maze corridor walls , distance traveled , and robot orientation are displayed to the user . According to Pradeep K. Khosla of Carnegie Mellon , the new center will study methods for using robots to monitor security and report problems . In all of these runs , the robot has a field of view of 500m . In developing the new robot , engineers at Automated Assemblies had to pay close attention to three sets of recirculating ball bearings that would support movement in the robot 's x , y , and z axes .
