  • Torque sensor, robot, and torque calculation method
    Patent number: 11898922
    Abstract: A torque sensor includes: a strain body; and an optical sensor configured to detect a deformation of the strain body. The strain body includes an outer peripheral portion having a ring shape, and an inner peripheral portion of which at least a part is disposed inside the outer peripheral portion in a radial direction. The optical sensor includes a scale fixed to one of the outer peripheral portion and the inner peripheral portion, and disposed between the outer peripheral portion and the inner peripheral portion, and a detector fixed to a remaining one of the outer peripheral portion and the inner peripheral portion, and disposed to face the scale between the outer peripheral portion and the inner peripheral portion.

  • ROBOT AND TORQUE SENSOR
    Publication number: 20170266814
    Abstract: A robot includes a rotation axis and a torque sensor. The torque sensor is disposed on the rotation axis, and includes a strain generating body and a strain sensor. The strain sensor is mounted on a portion of the strain generating body. The strain generating body includes an inner flange, a ring-shaped outer flange, and a plurality of spokes. The outer flange is disposed further outward than the inner flange in a radial direction of the inner flange. The plurality of spokes are disposed between the inner flange and the outer flange and connect the inner flange and the outer flange to each other. At least one spoke of the plurality of spokes is a separate spoke which is un-integral to the inner flange and the outer flange and on which the strain sensor is mounted.
