An operation system and an operation method that may improve operability are provided. The operation system includes a circuitry configured to determine a predicted value of an operator motion after a predetermined prediction latency from a current time based on a bio-signal using a prescribed machine learning model, the bio-signal captured from the operator and a controller configured to control a motion of a robot based on the predicted value. The operation method includes a step of determining a predicted value of an operator motion after a predetermined latency from the current time based on a bio-signal using a prescribed machine learning model, the bio-signal captured from the operator, and a step of controlling a motion of a robot on the predicted value.

Operation system and operation method

A powered leg prosthesis including a powered knee joint with a knee joint and a knee motor unit for delivering power to the knee joint, a powered ankle joint coupled to the knee joint including an ankle joint and an ankle motor unit to deliver power to the ankle joint, a prosthetic foot coupled to the ankle joint, a plurality of sensors for measuring a real-time input, and controller for controlling movement of the prosthesis based on the real-time input. In the powered leg prosthesis, at least one of the knee motor unit or the ankle motor unit includes at least one drive stage, where the drive stage includes a rotary element for generating torque and at least one looped element affixed around the rotary element and configured for transmitting the torque to another rotary element coupled to a joint to be actuated.

Powered leg prosthesis and control methodologies for obtaining near normal gait

A prosthetic socket fitment system for fitting a prosthesis to a patient can include at least one transceiver assembly in contact with an external frame coupled to a patient, and a processing module in electrical communication with the at least one transceiver assembly. The at least one transceiver assembly can be aligned to the bone of the patient and configured to generate a signal directed to the bone of the patient and receive a reflected signal from the bone of the patient.

Prosthetic socket fitment system

Systems and methods are provided for controlling a lower limb device having at least one powered joint. The method includes detecting a stumble event based on one or more sensor signals associated with an overall motion lower limb device, classifying the stumble event based on sensor signals following the sensor signals associated with the stumble event, and selecting a stumble recovery strategy for the lower limb device based on the classification of the stumble event.

Systems and control methodologies for improving stability in powered lower limb devices

A powered leg prosthesis includes powered knee joint comprising a knee joint and a knee motor unit for delivering power to the knee joint. The prosthesis also includes a prosthetic lower leg having a socket interface coupled to the knee joint and a powered ankle joint coupled to the lower leg opposite the knee joint comprising an ankle joint and an ankle motor unit to deliver power to the ankle joint. The prosthesis further includes a prosthetic foot coupled to the ankle joint, at least one sensor for measuring a real-time input, and at least one controller for controlling movement of the prosthesis based on the real-time input.
