Abstract
A detecting device including a pressure sensor that is deformed by a load from an outside and causes stress dispersion includes a slip detecting unit that calculates a pressure center position using a pressure value detected by the pressure sensor, calculates a movement value of the calculated pressure center position using a temporal change of the pressure center position, and detects a slip on the basis of the calculated movement value of the pressure center position. The pressure sensor has a multilayer structure in which two detecting units that detect pressure are arranged to hold a viscoelastic body made of a viscoelastic material that is deformed by a load from the outside.
