TORQUE SENSOR AND ROBOT COMPRISING THE TORQUE SENSOR

摘要

PURPOSE: A torque sensor and a robot in which the torque sensor is applied are provided to preciously measure a torque generated in a torque generator without errors caused by a gap between components. CONSTITUTION: A torque sensor and a robot in which the torque sensor comprises a torque generator(10), a transformation unit, and a sensor unit(40). The torque generator rotates around a fixing unit with a rotator by being joined to the rotator. The transformation unit is arrange between the torque generator and the fixing unit and formed into one body with the torque generator and the fixing unit. The transformation unit is consisted of a material in which an elastic transformation is possible and transformed in order to allow rotation of the torque generator around the fixing unit and recovered to an original position after the transformation. The sensor unit senses an extent of the transformation of the torque generator to the fixing unit.
