Abstract
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.
