Abstract: Automatic electromyography (EMG) electrode selection for robotic devices is disclosed. A plurality of signals from a corresponding plurality of sensors coupled to a skin of a user is received. For each pair of at least some pairs of the plurality of sensors, a sensor pair signature is generated based on differences in signals that are generated by the respective pair of sensors. Each of the sensor pair signatures is compared to a predetermined sensor pair signature to identify a particular pair of sensors. A signal difference between two signals generated by the particular pair of sensors is subsequently utilized to generate a command to drive a motor.

Abstract: Disclosed herein is a spacesuit including a liquid cooling ventilation garment, a soft exoskeleton, at least one biometric sensor, and an electronic controller in electronic communication with the liquid cooling ventilation garment, the soft exoskeleton, and the at least one biometric sensor. The electronic controller is configured to operate the soft exoskeleton based on electromyography data of the at least one biometric sensor to produce a desired change in orientation of the soft exoskeleton and corresponding user. The electronic controller is further configured to operate the liquid cooling ventilation garment based on temperature data of the at least one biometric sensor to maintain a user temperature within a predetermined user temperature range. In certain embodiments, the liquid cooling ventilation garment is in thermal communication with the soft exoskeleton and used for thermal management thereof. Such configurations reduce the physical and cognitive loading of the astronaut.

Abstract: Disclosed herein is a mechanical joint for an exoskeleton ankle. The mechanical joint includes a first connector (e.g., to attach to a foot), a second connector (e.g., to attach to a leg), a stack of at least partially nested cones between the first connector and the second connector (e.g., at an outstep of the foot), and a strand extending through the second connector and the cone stack. The second connector is configured to freely translate away from the first connector and freely tilt relative to the first connector. Similarly, the second cone is configured to freely translate away from the first cone along the strand and freely tilt relative to the first cone. Accordingly, the mechanical joint provides vertical support (e.g., of an exoskeleton structure) while minimizing angular resistance (e.g., about an ankle joint).

Abstract: A device comprising an arm cradle being configured to support and cradle a portion of an arm. The arm cradle includes a first side and a second side. The first side includes a matrix of selectable connector points comprising at least one selectable connector point in proximity to the front end of the cradle, at least one selectable connector point in proximity to a center of the cradle and at least one selectable connector point in proximity to a rear end of the cradle. A bracket having a first coupling member removably coupled to a selectable connector point and a second coupling member. An elevator post has a first end and second end. The first end is coupled to the second coupling member such that the bracket swivels about the first end automatically as the arm moves. A system and method are also provided.
