A master
workstation (101) for a robotic
system (100) for medical or surgical
remote operation, comprising: at least one mechanically ungrounded master control device (110) including a support or
handle (111) having a surface (112) for the palm of a surgeon; and an operating gripper (113) attached to the support (111) having two opposing operating interfaces (115, 116) for the fingers of a surgeon, and a control gripper (113) includes a first
rigid body portion (117) and a second
rigid body portion (118) placed side by side, the first
rigid body portion (117) being rotatably constrained to a support portion (111) around a first axis, and the second rigid body portion (118) being rotatably constrained to a support portion (111) around a second axis that coincides with or is parallel to the first axis, and the
tracking system is configured to individually detect position and orientation information of the first rigid body portion (117) and the second rigid body portion (118) of the operating gripper (113).
