The pitch and yaw axes of the manipulator use potentiometers for feedback of actual position. These potentiometers are non-linear. The software which uses the input from the potentiometers assumes linearity; therefore, with the proposed device the non-linearities can be found, and the error induced by the non-linearities can be reduced.
