Abstract: In a human-in-the-loop robotic control loop, the constrained forces and moments at the gripper (also called hand or end effector) of the manipulator are measured by a force-mement sensor. The resulting force and moment signals are scaled and fed as input voltages to motors in a hand controller to provide torques which oppose deflection of the hand controller. Thus, the operator feels the opposing torques which are proportional to the magnitude of the constrained forces and moments. The force feedback loop may be opened to selectively provide a passive control loop. In either the active or passive mode, the hand controller position signals may be selectively mapped to either gripper position signals or gripper velocity signals in order to control movement of the gripper in the desired manner.

Abstract: An aircraft flight control stick is mounted on a gimbal which provides left, right, forward and aft pivotal motion of the stick. A pivot member that is mechanically linked to the aircraft flight controls is attached to the gimbal through a uni-ball bearing which allows the pivot member to pivot independently of the control stick. A bell-shaped housing is slidably mounted on the control stick. The housing is spring-biased downward toward the pivot member so that a stud protruding upward from the pivot member plugs into a socket in the housing. A lever assembly mounted on the control stick and attached to the housing can be actuated to slide the housing away from the pivot member, thereby unplugging the stud from the socket to disengage the control stick from the aircraft flight controls. The downward facing housing circumscribes all possible motion of the stud while the control stick is disengaged. Release of the lever assembly allows a spring to urge the housing downward toward the stud.
