Dr. Robert Gregg
has devoted years of research to helping lower-limb amputees and stroke survivors walk again. A new grant from the National Science Foundation (NSF) has given that effort a significant boost.
The UT Dallas assistant professor of bioengineering
and mechanical engineering
has received a five-year, $500,000 NSF Faculty Early Career Development (CAREER) award
to support his work on broadening the scope of activities available to users of powered lower-body prosthetics and orthotics. In 2013, the year he arrived at the Erik Jonsson School of Engineering and Computer Science
, Gregg received a $2.3 million grant
from the National Institutes of Health for similar work.
Dr. Robert Gregg
has dedicated much of his life to helping stroke victims and lower-leg amputees learn to walk again. Motivated in part by a desire to help wounded veterans, the UT Dallas assistant professor of bioengineering and mechanical engineering is conducting research that is opening doors to a smoother leg motion, one that allows amputees to walk more naturally at various speeds on variable inclines.
His latest research on the subject, published online by IEEE Transactions on Robotics
, describes his powered knee-ankle prosthesis that has been tested on three above-knee amputee subjects. Gregg likens this new development to horseback riding.
Dr. Robert Gregg, an assistant professor of mechanical engineering and bioengineering who joined the Erik Jonsson School of Engineering and Computer Science
this fall, is a recipient of a $2.3 million grant from the National Institutes of Health for research that will combine robot control theory and physical rehabilitation to revolutionize and improve prosthetic limbs and orthotic devices.
“According to the American Society of Mechanical Engineers report ‘2028 Vision for Mechanical Engineering,’ mechanical engineers will need to collaborate with partners worldwide in order to apply innovative solutions and best practices to improve quality of life for all people,” said Dr. Mario Rotea, head of the Department of Mechanical Engineering
. “Dr. Gregg’s research will contribute to this vision. His research combines mechanical systems, control theory, and embedded hardware and software to create next-generation prosthetics without the limitations of conventional solutions.
Two UT Dallas educators recently received the 2018 Provost's Awards for Faculty Excellence in Research Mentoring in recognition of their superior support and guidance to student researchers.

A University of Texas at Dallas professor applied robot control theory to enable powered prosthetics to dynamically respond to the wearer’s environment and help amputees walk.
In research available online and in an upcoming print issue of IEEE Transactions on Robotics,
wearers of the robotic leg could walk on a moving treadmill almost as fast as an able-bodied person.
“We borrowed from robot control theory to create a simple, effective new way to analyze the human gait cycle,” said Dr. Robert Gregg
, a faculty member in the Erik Jonsson School of Engineering and Computer Science
and lead author of the paper. “Our approach resulted in a method for controlling powered prostheses for amputees to help them move in a more stable, natural way than current prostheses.”
