Mobility impairments among older adults and individuals with neuromuscular weakness motivate the need for timely and adaptive exoskeleton assistance. This paper presents a human-in-the-loop muscle sensing and control system based on capacitive microphone sensors (CMS) that capture subtle mechanical
Functional Electrical Stimulation (FES) is a critical therapy for motor rehabilitation, yet the rapid onset of muscle fatigue severely limits its efficacy. This paper presents the design, implementation, and validation of a comprehensive, intelligent closed-loop FES system designed to provide effect…
Rehabilitative robotics, particularly lower-limb exoskeletons (LLEs), have gained increasing importance in aiding patients regain ambulatory functions. One of the challenges in making these systems effective is the implementation of an assist-as-needed (AAN) control strategy that intervenes only whe…
Human-robot cooperation is vital for optimising powered assist of lower limb exoskeletons (LLEs). Robotic capacity to intelligently adapt to human force, however, demands a fusion of data from exoskeleton and user state for smooth human-robot synergy. Muscle activity, mapped through electromyography
Stiffness modulation in walking is critical to maintain static/dynamic stability as well as to minimize energy consumption and impact damage. However, optimal, or even functional, stiffness parameterization remains unresolved in legged robotics. We introduce an architecture for stiffness control uti
Active lower limb prosthetics rely on the detection of gait mode to direct controller response. The majority of systems require feedback from the prosthetic and/or inertial measurement units (IMUs). Reliance on movement delays classification, reducing the range of patient activities and terrain trav…
