Abstract: An example traction drive includes a first ring having an inclined surface that is inclined at a first angle; a second ring having a respective inclined surface that is inclined at a second angle different from the first angle, such that the inclined surface of the first ring and the respective inclined surface of the second ring form a groove; a third ring disposed opposite to the first ring and the second ring, and having a respective groove disposed on a surface of the third ring; and a plurality of rollers disposed between, and configured to roll within, (i) the groove formed by the inclined surface of the first ring and the respective inclined surface of the second ring, and (ii) the respective groove of the third ring.

Abstract: A robotic arm system is provided. The system includes a one or more roll and/or angle actuators driven by a unidirectional drive. One or more clutches allow the actuators to engage and disengage with a drive shaft or a reverser assembly or angle drive coupled to the drive shaft, thereby permitting changes in rotational direction for the actuators without a change in the rotational direction of the drive.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for causing a transducer to transmit an acoustic input signal into a member of a device. Receiving a detection signal representing reverberations of the input signal traveling within the member from a receiver. Detecting a contact of the member with an object external to the member based on a change in the detection signal, where the change in the detection signal represents an alteration in the reverberations of the input signal caused by the contact of the member with the object. Determining a position along the member of a point of the contact of the member with the object based on the change in the detection signal.
