Abstract
A measurement assembly for determining a torque applied to a shaft including a disk coupled to a motor such that the motor is to drive rotation of the disk about a central axis. The measurement assembly also includes a first ring and second ring coupled to the disk and the shaft, respectively, and a sensor unit to measure a rotational displacement between the first and second rings about the central axis. The measurement assembly further includes one or more deformable members coupled between the disk and the shaft, each including a pair of ends and a body extending therebetween. For each deformable member, one of the ends is coupled to the shaft and the other end is coupled to the disk such that a rotation of the shaft relative to the disk about the central axis is to cause the deformation of the body.
