Developing an advanced controller to balance agility and stability in a wearable ankle robot will maximize performance for the user.
Forming mathematical models to describe ankle mechanics can assist in developing advanced lower limb prosthetics.
Quantifying reasons behind ACL injuries based on sex will increase understanding help develop better rehabilitation methods.
The purpose of this research is to investigate the viability of negative damping as a control scheme for a wearable ankle exoskeleton. Negative damping can be thought of as the opposite of friction – it adds energy to a system instead of removing it. The muscle activity and gait motion of subjects wearing an externally-powered
This research project investigates the stability of the ankle in inversion and eversion using variable negative damping coefficients: -0.3, 0, 0.3. The angle of motion is tested by making a comparison between 5 and 7 degrees angles of motion. Currently the researcher is focusing on creating graphs and build a reasoning interpretation of the experimental
The development of wearable robots has the potential to drastically improve human lives. This study focuses on using a wearable ankle robot to quantify lower-limb motor control. After creating a video game for human subjects to play, kinematic data and electromyographic (EMG) data was collected from ten healthy subjects. This study continues previous research on
This research provides a system model for the torque generation of a healthy human ankle undergoing voluntary reflex. This project also provides a physical platform to further study the ankle models in a diseased population. The results of this study will provide a baseline parametric model upon, which differences in voluntary reflex models from diseased
Can you walk on a treadmill as comfortably as you would over ground? While this seems challenging, the implementation of a self-paced mode in the instrumented treadmill enables the treadmill to adjust itself to the speed of the subject rather than the subject adjusting to a fixed speed thereby improving the comfort level. A study
