Current Projects


Physical Therapy Assist Device – Medical Robots

In conjunction with the bioengineering department, Kinetic Muscles Inc, and Banner Health, a therapy assist device is being developed which will aid stroke patients in neural re-training using a wearable robotic exoskeleton. The device will assist upper arm movements for feeding and reaching. RUPERT – Robotic Upper Extremity Repetitive Training

Wearable Robotic Exoskeletons – Medical Robots
Compliant actuation systems are designed to safely interact with humans. These actuators, tunable leaf springs, springs-over-muscles, and jack-springs, are lightweight, energy efficient, power reducing, and safe. They will be used in areas such as stroke rehabilitation, physical rehabilitation, muscle assistance, and gait training.

Human Navigational Principles
Collaboration with Psychology to develop models for human navigational and pursuit strategies. Research the unconscious, low-level motor vision algorithms used by humans. A mobile robot is designed as a test-bed.

SPARKy – Medical Robots
A powered bionic ankle is being developed for the Military Amputee Research Program. The powered ankle stores energy in springs as the leg rolls over the ankle and releases the energy in a powerful burst for push-off. SPARKy (SPring Ankle with Regenerative Kinetics) allows a person to walk with improved gait symmetry and normal push-off power.

Powered Ankle Foot Orthosis – Medical Robots
A powered ankle foot orthosis is being developed for the National Institutes of Health. The powered orthosis stores energy in springs as the leg rolls over the ankle and releases the energy in a powerful burst for push-off. The repetitive training paradigm is being used to assist stroke survivors who are paralyzed on one side.

Embedded Computing for Education
Motor control labs are developed which allow the user to automatically generate, real-time, embedded code for PC’s. Examples include a compliant joystick and an active suspension which dynamically adjusts the equilibrium position of the suspension.
