Abstract

Embodiments include a system for controlling motion of a human limb. The system may include a plurality of mechatronic devices, each of which may be in communication with at least one other of the plurality of mechatronic devices. Each of the mechatronic devices includes one or more of a processor, an actuator, or a sensor. One or more of the mechatronic devices may be configured to generate a control state for at least one other of the plurality of mechatronic devices based on the communicated data. In one embodiment, the communicated data is used to synchronize the mechatronic devices. In one embodiment, one or more of the mechatronic devices is configured to receive executable instructions for controlling an actuator via a communications interface.
