Abstract: An example torque controlled actuator includes a frame, and one or more timing belt stages coupled in serial on the frame. The timing belt stages include an input stage for coupling to a motor and an output stage for coupling to a load, and the timing belt stages couple rotation of the motor to rotation of an output of the output stage. The torque controlled actuator also includes one or more belt idlers coupled to the frame that contact a timing belt of the output stage, and a strain gauge coupled to the frame to determine a tension of the timing belt of the output stage based on force applied by the timing belt of the output stage to the one or more belt idlers.

Abstract: A device is provided that comprises a hardware segment and an actuator to adjust a position of the segment within a range of positions. The device also comprises an encoder to rotate about an encoder axis responsive to the actuator adjusting the position. The device also comprises data storage that includes a dataset indicating offset angles between a reference configuration and a plurality of configurations of the encoder. The device also comprises a controller to cause the actuator to adjust the position to an end of the range of positions, responsively identify a range of encoder positions of the encoder that corresponds to the range of positions of the segment, modify the dataset such that the reference configuration corresponds to an end of the range of encoder positions, and determine a mapping between the offset angles indicated by the modified dataset and the range of positions of the hardware segment.
