Total Energy Shaping for Task-Invariant Control of Lower-Limb Exoskeletons
We present a total energy shaping control methodology for the development of portable lower-limb assistive exoskeletons and orthotic devices that help reduce the human’s effort and augment natural motion. Current robotic exoskeletons restrict joint motion to pre-defined position trajectories during gait rehabilitation; such methods aim to replicate...

Virtual Body-Weight Support via Lower-Limb Exoskeleton
Summary:This is a novel control system for powered lower-limb exoskeletons (or orthoses) that provides body-weight support (BWS) for people who have sustained a stroke and other neurological injury. Patients are provided with BWS during conventional gait retraining to help them produce the coordinated muscle activities needed for walking. Although current...

Unified Lower-Limb Prosthetic Control Strategy
Non-Confidential Description: This technology defines a novel control strategy for a powered prosthetic leg that unifies the entire gait cycle, eliminating the need to switch between controllers during different periods of gait. Current control methods divide the gait cycle into several sequential periods with independent controllers, resulting...
