<title>A Tactile Sensor With Electrooptical Transduction</title>

Abstract

The tactile sensor described in this paper employs two stages of transduction in converting impressions on its touch surface into conveniently processed electrical signals. One stage is a pure mechanical deflectometer while the other is an arrangement using electro-optical transducers. This transduction concept contributes to a robust sensor design suitable for operation on the factory floor. Design, performance, and application of the tactile sensing system are described. The application is an operation involving assembly of a thin flexible diaphragm in the lip of a rigid cap.
