Potentiometer: a variable resistance device that expresses linear or angular displacements in terms of voltage. Position sensors. Clipping is a handy way to collect important slides you want to go back to later. A sensor is part of a larger system that contains other detectors, memory devices, data recorders, actuators, signal conditioners and signal processors. Measurement is an important subsystem in any major system, whether it may be a mechanical system or an electronic system. The optical position sensors are an essential component in self-driving cars. Exact knowledge of the position of a vehicle is a fundamental problem in mobile robot applications.
