Abstract
A motorized joint unit comprises a pair of shells defining an inner cavity, the pair of shells adapted to be connected to adjacent links of an articulated mechanism. A rotor and stator in the inner cavity are actuatable to cause a relative rotation therebetween. A shaft connected to the rotor to rotate with the rotor relative to the stator. A support coupled to the shaft by a mechanism, the support being connected to one of the shells to impart a rotation of the shaft to the shell, the support defining an annular wall. One or more strain gauges are located on said annular wall of the support. A printed circuit board (PCB) is applied against the annular wall and electrically connected to the at least one strain gauge, the PCB adapted to be electrically linked to a controller.
