摘要:
A rapidly modulated hydraulic supply is disclosed. The rapidly modulated hydraulic supply can include a chamber for receiving fluid. The rapidly modulated hydraulic supply can also include a displacement member operable to displace the fluid from the chamber. In addition, the rapidly modulated hydraulic supply can include a flow modulation system operable to vary the flow rate of the fluid output from the chamber. A first flow rate corresponds to a first output pressure, and is different from a second flow rate corresponding to a second output pressure for a like movement of the displacement member.

An exoskeleton is disclosed. The exoskeleton can include support members rotatably coupled together about a joint. The joint can define a degree of freedom, which can correspond to a degree of freedom of a human extremity, such as hip medial/lateral rotation, ankle medial/lateral rotation, shoulder medial/lateral rotation, or wrist pronation/supination rotation. One or more parasagittal planes through the human extremity can intersect the joint to minimize a gravity-induced moment on the first joint during operation of the exoskeleton.

A legged robotic device is disclosed. The legged robotic device can include a mechanism formed at least in part by a plurality of support members coupled together for relative movement defining a plurality of degrees of freedom, at least some of the plurality of degrees of freedom corresponding to degrees of freedom of a human leg. The legged robotic device can also include a primary drive actuator operable to apply a force or a torque to the support members in a first of the plurality of degrees of freedom. In addition, the legged robotic device can include a second actuator operable to apply a force or a torque to the support members in a second of the plurality of degrees of freedom. The mechanism can be configured to move in a gait-like motion that emulates human gait. The primary drive actuator can be sufficient to actuate the mechanism to move the mechanism in the gait-like motion. The mechanism can be dynamically modified by actuating the second actuator.

Device coordinated robotic control technology is described. A network of robotic devices (100) is established. An anthropomorphic motion is sensed from an operator (300). One or more signals are generated that are representative of at least a portion of the anthropomorphic motion. The one or more signals are converted into a collective set of commands to actuate the network of robotic devices (100). The collective set of commands is functionally equivalent to the anthropomorphic motion.

A legged robotic device is disclosed. The legged robotic device can include a plurality of support members coupled together for relative movement defining a plurality of degrees of freedom, which can correspond to degrees of freedom of a human leg. The legged robotic device can also include actuators to apply forces or torques to the support members in the degrees of freedom. In addition, the legged robotic device can include potential energy storage mechanisms associated with the degrees of freedom operable to store potential energy as a result of relative movement of the support members in the degrees of freedom and to provide at least a portion of the stored potential energy to the support members as compensating forces or torques to assist the actuators. In one aspect, elastic potential energy can be stored. A spring rate and/or a zero position of the potential energy storage mechanisms can be dynamically variable.
