摘要:
A method and system for controlling an intelligent assist device, robot, or other powered system that is partially or fully directed by the intent of a human operator. The method and system includes measuring a force or motion imparted by the human operator to a control. The measurement is determined with respect to the motion of the machine at a point of the machine that allows the benefit of collocation of sensing and actuation, or of approximation of such collocation. The system includes a support attached to the machine at the beneficial point, and a plurality of sensors to measure the force, torque, or motion imparted by the human operator to the support with respect to the beneficial point. The method and system provide improved stability of control of the system, and improved responsiveness to the intent of the human operator.

A touch interface device includes a touch surface, a first electrode, and a second electrode. The first electrode is coupled with the touch surface. The first electrode also configured to receive a first haptic actuation electric potential. The second electrode is coupled with the touch surface. The second electrode also is configured to receive a different, second haptic actuation electric potential having an opposite polarity than the first haptic actuation potential. The first and second electrodes generate an electrostatic force that is imparted on one or more appendages of an operator that touches the touch surface above both the first electrode and the second electrode in order to generate a haptic effect.
摘要:
A transmission or actuator offering multiple rotational outputs proportionate in speed to that of a common rotational input, each output according to its own ratio. The ratios are continuously variable between positive and negative values, including zero, and may be varied by electromechanical actuators under computer control. The transmission relates the output speeds one to another under computer control, and thus makes possible the establishment of virtual surfaces and other haptic effects in a multidimensional workspace to which the transmission outputs are kinematically linked. An example of such a workspace is that of a robotic or prosthetic hand.

A pelvic support unit is coupled to a base by a powered vertical force actuator mechanism. A torso support unit, which is affixed to the patient independently of the pelvic support unit, is connected to the base by one or more powered articulations which are actuable around respective axes of motion. Sensors sense the linear and angular displacement of the pelvic support unit and the torso support unit. A control unit is coupled to these sensors and, responsive to signals from them, selectively control the displacement actuator and articulation(s).
摘要:
A system and method are presented to provide assist to a user by means of an exoskeleton with a controller capable of making the exoskeleton display active impedance. The exoskeleton assists the user by reducing the muscle effort required by the user to move his or her extremities. In one embodiment, a single-degree-of-freedom (1-DOF) exoskeleton assists a user with single-joint movement using an active impedance controller. In another embodiment, a multiple-degree-of-freedom (multi-DOF) exoskeleton assists a user with multiple-joint movement using an active impedance controller.
摘要:
An apparatus and method for conveying sensory information from a distal location on a prosthetic limb, to a proximal location on the body of the wearer. The apparatus comprises a detector for mounting in a prosthesis and a stimulator for engaging the skin of the prosthesis wearer. Tactile, haptic and other information including surface-normal force, shear force, vibration, and/or temperature are sensed, conveyed, processed, and displayed, such that the wearer of the prosthetic has improved sensation and awareness from distal parts of a prosthetic, such as a fingertip.

摘要:
An intelligent assist system having a modular architecture, coordinated by electronic communication links between the modules, is provided. Motion modules provide an assist upon actuation, and are in communication with computational nodes. Communication links between at least two of the computational nodes carry information between the nodes that actuate a motion module.
