Abstract: Example methods and devices for touch-down detection for a robotic device are described herein. In an example embodiment, a computing system may receive a force signal due to a force experienced at a limb of a robotic device. The system may receive an output signal from a sensor of the end component of the limb. Responsive to the received signals, the system may determine whether the force signal satisfies a first threshold and determine whether the output signal satisfies a second threshold. Based on at least one of the force signal satisfying the first threshold or the output signal satisfying the second threshold, the system of the robotic device may provide a touch-down output indicating touch-down of the end component of the limb with a portion of an environment.

Abstract: Examples are provided that describe a rotary hydraulic valve. In one example, a rotary valve comprises a sleeve with a plurality of selector ports and one or more control ports spaced along a length of the sleeve. A spool comprising an internal chamber is provided within the sleeve. The spool includes a plurality of selector openings and one or more control openings spaced along a length of the spool. The rotary valve also comprises a controller for determining a given rotational movement of the spool based on a selection of a pressurized fluid. The rotary valve also comprises a motor coupled to the spool and for rotating the spool within the sleeve based on the given rotational movement. The motor is configured to cause a given alignment of the spool to the sleeve resulting in a pathway through the internal chamber of the spool and out to the sleeve.

Abstract: A regenerative shock absorber that include a housing and a piston that moves at least partially through the housing when the shock is compressed or extended from a rest position. When the piston moves, hydraulic fluid is pressurized and drives a hydraulic motor. The hydraulic motor, in turn, drives an electric generator that produced electric energy. The electric energy may be provided to a vehicle, among other things. The regenerative shock absorber may also provide ride performance that comparable to or exceeds that of conventional shock absorbers.
