Two-degree-of-freedom rope-driven finger force feedback device

The present invention provides a two-degree-of-freedom rope-driven finger force feedback device. The two-degree-of-freedom rope-driven finger force feedback device includes a hand support mechanism, a thumb movement mechanism, an index finger movement mechanism, and a handle mechanism. The hand support mechanism includes a motor, a motor shaft sleeve, a sliding rail, and an inertial measurement unit (IMU) sensor. The thumb movement mechanism includes a long rotary disc, a torque sensor, an angle sensor, a thumb sleeve, a pressure sensor, two links, a thumb brace, and a thumb fixing ring. The handle mechanism includes a cylindrical handle, a pressure sensor, a flexible fixing band, and a slider. Torque is driven between the rotary disc and the motor by using a rope. The handle mechanism is movable forward and backward and is capable of automatic restoration. By means of the present invention, the problems of the high costs of a conventional finger force feedback device and the unadjustable characteristic of the conventional finger force feedback device are overcome. The device can be tightly worn and has a self-adaptive degree of freedom. Rope driving can ensure a gentle, smooth, and real feedback force. By means of the mounted sensors, information such as a hand posture, a rotation angle and a grip force of a thumb and an index finger, and a contact force of a middle finger can be transmitted in real time.

System and method for motion mode management

Systems and methods for motion mode management include a computer-assisted device having an input control, a repositionable structure, and a controller coupled to the input control and the repositionable structure. The controller is configured to detect movement of the input control, control movement of the repositionable structure based on the movement of the input control, determine whether the movement of the input control is likely to include one or more components of a mode switching movement of the input control, and in response to determining that the movement of the input control is likely to include one or more components of the mode switching movement, temporarily disable mode switching in response to movement of the input control. The mode switching movement changes a mode of operation for the device. In some embodiments, the temporarily disabling prevents changing the mode of operation when the movement is a mode switching movement.

DETECTION OF USER TOUCH ON CONTROLLER HANDLE
20230106285 · 2023-04-06 · ·

Implementations relate to detecting user touch on a controller handle. In some implementations, a non-controlling mode of a control system is activated, and in the non-controlling mode, one or more actuators are controlled to cause a vibration to be provided on a handle of a controller. The vibration is sensed with one or more sensors, and a difference in the vibration is determined to have occurred relative to a reference vibration using the one or more sensors, where the difference satisfies one or more predetermined thresholds. A controlling mode of the system is activated in response to determining the difference in the vibration, and the vibration is modified on the handle in response to detecting the change in the vibration.
