ABSTRACT:
A system and method for verifying the positional integrity of a robotic arm are disclosed. The robotic arm includes a servo mechanism which causes movement of the arm. The servo mechanism has a position encoder which indicates the relative position of the robotic arm with respect to a fixed reference point. A flag is attached to the robotic arm. A sensor for detecting the flag is attached to a point which is fixed with respect to the motion of the robotic arm. The sensor is located at a point such that the flag will pass by the sensor during the normal course of travel of the robotic arm. Each time the flag passes by the sensor, the sensor generates a signal. A controller which is coupled to the position encoder and to the sensor compares the position of the robotic device indicated by the position encoder at the time the sensor detects the presence of the flag with a predetermined value.
