A mechatronic device includes two arms extending from a base in a first direction and shaped to be handheld by an operator, the two arms having free ends forming a gripper and arranged to move closer together by rotation from a rest position to an active position, a motor housed in the base, an actuator mounted between the arms, and a means for controlling said actuator, the actuator connected to the motor so as to be driven in movement in translation in the first direction. The actuator also has a first contact surface that forms a cam with a respective second contact surface on each arm, the first contact surface remaining engaged with the second contact surface. The control means controls the movement in translation of the actuator to produce a movement in rotation of the arms that applies a chosen force of the gripper in its active position.

Mechatronic forceps

A device, having first and second motor units, for generating a torque on an output member in response to a torque setpoint. The first motor unit includes at least one motor of a first power, or small motor, having a shaft to which the output member is connected. The second motor unit includes at least one motor of a second power higher than the first power, or large motor, having a shaft rotationally connected to the output member via viscous coupler, and computer programmed, in response to a torque setpoint, to power the second motor unit so that the viscous coupler provides a viscous torque conforming to the torque setpoint. Further, in parallel with this, the first motor unit is powered so that it produces the additional torque between the torque setpoint and the viscous torque until the viscous torque reaches the value of the torque setpoint.
