Abstract: An apparatus for a robotic limb includes one or more limb segments connected via one or more joints. The robotic limb may feature one or more dual-reduction quasi-quasi-direct-drive joint actuators that permit the robotic limb to move throughout a scene. The robotic limb may further include an end-effector connected to a free end of the robotic limb with one or more opposable fingers comprising a four bar linkage. The end-effector may include a main actuator that actuates the one or more fingers via the four-bar linkages to complete various tasks.

Abstract: In one embodiment, a method includes, by an electronic device, receiving a digital input indicating a type of movement. Streaming sensor data corresponding to movements of a first user can be accessed from one or more sensors of one or more wearable devices on the first user. Displacement data corresponding to the movements of the first user can be generated based on the streaming sensor data and the indicated type of movement. One or more repetitions represented in one or more corresponding segments of the displacement data can be identified based on the displacement data. The displacement data corresponding to each identified repetition may substantially match a predetermined movement signature associated with the type of movement. One or more performance metrics can be calculated for one or more of the identified repetitions. Instructions can be provided for presenting a user interface including information referencing the performance metrics.

Abstract: A drum for a combination washer dryer can include a plurality of sections. The sections can be interconnected by a plurality of flexible gaskets. The drum can be configured to expand and contract radially. The drum can radially expand to dry wet laundry during a drying phase following a washing phase in which laundry is washed.
