Abstract
Devices and systems for producing rotational actuation are described. Hydraulic and pneumatic actuators can produce and control rotational motion. A rotary joint may be configured to allow parallel coupling of multiple actuators, and thus increase the range of rotation of the actuators when considered collectively. The actuators may include pistons and piston rods having torus shapes. Methods of manufacturing rotary joints are also described.
Claims12
A hydraulic rotary actuator system, the system comprising:
- one or more actuators, each actuator comprising:
- a torus cylinder;
- and
- a piston rod, wherein the piston rod is inserted inside the torus cylinder;
- an axle assembly, wherein the piston rod of each actuator couples the torus cylinder to the axle assembly;
- and
- a drive mechanism, wherein the piston rod of each actuator is coupled to the drive mechanism.
