Abstract
A distance tracking control system, for use with a working member such as a robotic head, includes a non-contact distance sensor for sensing a distance of the working member from a surface. An actuator is provided for making positional adjustments of the working member in response to changes in the distance sensed by the non-contact distance sensor. A controller is connected to the distance sensor and the actuator. The controller receives data from the non-contact distance sensor and then sends signals to the actuator to make positional adjustments of the working member.
