Abstract: An instrument drive mechanism comprises an outer shell having an open-ended receptacle. An internal gear is secured inside the open-ended receptacle and immovable relative to the outer shell. An interface cover is rotatably mounted to the open-ended receptacle, the interface cover configured to be connected to an instrument, the interface cover rotatably supporting at least one cover shaft with an output adapted to be rotatingly coupled to the instrument. A drive system is rotatably mounted to the open-ended receptacle and connected to the interface cover to rotate with the interface cover, the drive system having at least two motor units, a coupling assembly between each of the at least one cover shaft and a corresponding one of the motor units for releasably coupling a motor unit shaft to the cover shaft, for the at least one said motor unit coupled to each said at least one cover shaft to transmit a degree of actuation thereto, and one said motor unit having a gear coupled to internal gear to drive a rotation of the interface cover and drive system relative to the outer shell.

Abstract: An admittance mode control system for a robotic arm comprises 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: 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 assembly of links and motorized joint unit comprises two or more links. The links have a tubular body, one or both ends of the tubular body being an open end. A motorized joint unit has a first portion received in the open end of the tubular body of a first of the links so as to be secured relative to the first of the links. A second portion is 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 relative to the second of the links. A protective sleeve has a tubular body mounted over part of the motorized joint unit to cover a gap between the first and the second of the links, the protective sleeve having a rigid annular member and a flexible annular member, the flexible annular member foldable onto the rigid annular member.

Abstract: A motorized joint unit of a mechanism comprises a rotor assembly and a stator assembly operatively assembled and configured for being secured to respective links of the mechanism. The rotor assembly and the stator assembly respectively include a rotor and a stator concurrently operable to cause a rotation of a rotor of the rotor assembly relative to a stator of the stator assembly about a rotational axis, a receiving volume delimited by one of the rotor assembly and stator assembly, the rotational axis passing through the receiving volume. A brake assembly is located at least partially in the receiving volume and comprising a brake plunger having a brake surface for brakingly engaging with a corresponding surface of the rotor assembly, the brake plunger displaceable in translation in the brake assembly, and a solenoid coil actuatable to displace the brake plunger against the rotor assembly.

Abstract: A dielectric for a capacitive-based tactile sensor of the type having a pair of spaced apart conductive plates with the dielectric conductively therebetween, comprises a body of a non-rigid dielectric polymeric material. The body is shaped into a microstructure defined by a plurality of members adapted to extend from one of the conductive plates to the other. Some of the members comprises a first feature shaped to have a first end surface and a second end surface. Second features are integral with the first feature and project from the second end surface. A cross-section area of each of the second features is substantially smaller than a cross-section area of the first feature at the second end surface. A height of the first feature in a distance between the conductive plates is substantially greater than a height of the second features. A capacitive-based tactile sensor with the dielectric is also provided.
