Lower Limb Prostheses with Dynamic Joint Alignment
Dynamic alignment is a new concept that actively realigns the residual limb with the ground reaction force during the stance phase of gait to reduce socket loading.
Improved Musculoskeletal Model in OpenSim of Below-Knee Amputees
We are developing a new forward dynamics musculoskeletal model in OpenSim in Colloaboration with
Locomotion Research Group
at UMass-Amherst for simulating amputee gait that accounts for an amputee's unique anatomy.
Powered Hip Exoskeleton
This project focuses on developing new mechanisms to actuate the hip that leverage the natural dynamics during gait.
Passive Spine Exoskeleton
This is a two-fold project focused on modeling the dynamics of external assistance to the torso and using pattern recognition to identify the user's intent using surface electromyography and inertial sensors.
Pattern Recogition of Movements of the Torso
In this project we are using surface electromyography and inertial sensors to recongize movements of the torso for use in activity monitoring and control of an exoskeleton.
MR-Compatiable Knee and Leg Extension Ergometer
New insights on the muscle and tissue during dynamic loading and activation of the limbs during and magnetic resonance imaging (MRI) and spectroscopy (MRS). This project works on developing a MR-compatible knee ergometer that will work in the new 3T Siemens Skyra MR machine on the Amherst campus.
Robust and Compact Load Cell Design
In this project a new type of load cell is being developed based on the Hall Effect in order to create low-cost and durable load cells for use in robotic and prosthetic applications.
A Physically Interactive Surface Robot
The goal of this project is to create new low-cost, interactive robots for physically immersing the user in a virtual world.
Understanding Human Intent through Physical Interaction
The goal of this project is to enable a robot to actively collaborate with a person to move an object in an efficient and smooth manner.
Two-Wheeled Inverted Pendulum Walker
This project explores how to dynamically assist mobility-impaired users with balance and fall prevention using a robotic walker based on two-wheeled inverted pendulum.
Past Research Projects
uBot-7: A Dexterous Whole-Body Mobile Maniupulator
In collaboration with
Laboratory of Perceptual Robotics
at UMass-Amherst, the seventh generation uBot was developed with enhanced sensing through the addition of series elastic actuators at each joint.
Intelligent Terrain Adaptive Ankle Prostheses
An ankle prosthesis that uses semi-active damping as a mechanism to provide active slope adaptation.
Haptic Feedback Tactor Array
A modular tactor array used provide proprioceptive feedback of wrist motion for upper limb amputees.
A Powered Knee and Ankle Prosthesis
Investigation into the design and control principles for powered lower limb prosthesis. This project was conducted previously in the
Center for Intelligent Mechatronics
at Vanderbilt University.
