Kind Code:
B2
Abstract:
[Problem] To provide a torque sensor that can be miniaturized, a robot, and a torque computation method.[Solution] A torque sensor 1 includes a strain body 3 and optical sensors OS1-OS4 for detecting the deformation of the strain body 3. The strain body 3 includes a ringshaped outer peripheral part 5, and an inner peripheral part 7 at least a portion of which is disposed radially inward of the outer peripheral part 5. The optical sensors OS1-OS4 include: scales SC1-SC4 that are fixed to the inner peripheral part 7, and that are disposed in between the outer peripheral part 5 and the inner peripheral part 7; and detection units D1-D4 that are fixed to the outer peripheral part 5, and that are disposed so as to face the scales SC1-SC4 in between the outer peripheral part 5 and the inner peripheral part 7.
