Abstract
A mechanical teleoperated device for remote manipulation includes a slave unit having a number of slave links interconnected by a plurality of slave joints; an end-effector connected to the slave unit; a master unit having a corresponding number of master links interconnected by a plurality of master joints; and a handle connected to a distal end of the master unit. The device further includes first device arranged to kinematically connect the slave unit with the master unit, second device arranged to kinematically connect the end-effector with the handle, and a mechanical constraint device configured to ensure that one master link of the master unit is guided along its longitudinal axis so that the corresponding slave link of the slave unit always translates along a virtual axis parallel to the longitudinal axis of the guided master link in the vicinity of the remote manipulation when the mechanical teleoperated device is operated.
