    摘要: Disclosed are robotic systems, methods, bipedal robot devices, and computer-readable mediums. For example, a robotic system may include a robotic body, a robotic hip connected to the robotic body, and a ball screw connected to the robotic hip. Further, the robotic system may include a robotic leg connected to the robotic hip parallel to the ball screw. Yet further, the robotic hip includes a motor that is linearly movable to one or more positions along the ball screw between one end of the robotic leg and an opposite end of the robotic leg.

    摘要: A robotic system may include an incremental encoder coupled to a joint of the system. The robotic system may include a memory configured to store representations of angular positions of the joint. The robotic system may include a motor coupled to the joint, where rotation of the joint while the motor is powered off (i) causes rotation of the motor such that electric power is generated, and (ii) updates the angular position of the joint. The robotic system may use the electric power to power on the incremental encoder and the memory while the robotic system is powered off. One or more processors may obtain, when the robotic system powers on after being powered off, the updated angular position of the joint from the memory, where the incremental encoder provides the updated angular position to the memory while the robotic system is powered off.

    摘要: The present application discloses implementations that involve shutdowns of a robotic system. An example may include controlling, by a robotic system, a plurality of motors of the robotic system with a central processing unit (CPU). The example may also include determining, by the robotic system, an error condition of the robotic system, where the error condition prevents the CPU from controlling at least one of the plurality of motors. The example may also include causing a plurality of motor driver boards to control the plurality of motors of the robotic system in response to determining the error condition of the robotic system. The example may also include receiving, by the plurality of motors, one or more commands from the plurality of motor driver boards to move the robotic system to a stationary position and park the robotic system in the stationary position.
