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.

Abstract: An admittance mode control system for a robotic arm includes an admittance switch adapted to be mounted to the robotic arm. A rotary contact connects a control circuitry to the admittance switch. The control circuitry is adapted to be mounted to the robotic arm, rotational degree(s) of freedom being present between the control circuitry and the admittance switch, the control circuitry interpreting signals to filter circuit misconduct from admittance switch activation. The control circuitry is adapted to communicate a request for admittance to a robot driver for the robot driver to convert an operation of the robotic arm into admittance mode.

Abstract: An assembly of links and motorized joint unit of a mechanism comprises one or more pairs of links, each said link having a tubular body, at least one end of each of the tubular body being an open end having at least one connector. A motorized joint unit has a first portion received in the open end of the tubular body of a first of the links, the motorized joint unit secured to the at least one connector of the first of the links, a second portion rotatable relative to the first portion by actuation of the motorized joint unit, the second portion received in the open end of the tubular body of a second of the links, the motorized joint unit secured to the at least one connector of the second of the links. A protective sleeve has a tubular body rotatably mounted over the at least one connector of each of the first and the second link, the protective sleeve concealing the connectors and a joint between the pair of links.
