Overall Research Project Description Technologies like rehabilitation exoskeletons aim to help humans to regain motor skills that have been lost because of injury or disease. One skill of particular interest is to re-train how to walk. Walking is a challenging dynamic task involving multiple degrees-of-freedom needing to coordinate in order to achieve forward movement without falling. In order to study how humans learn to perform tasks like this, we are studying the biomechanics and motor learning involved in the development of a similarly dynamic and tricky task – learning to ride a unicycle. We plan to develop a human subject experiment where we will collect human motion capture and other biomechanics-related signals as subjects learn to ride a unicycle under various conditions. For instance, we might try to partner with the FSU Flying High Circus to determine if motor learning improves with coaching versus without. We may eventually seek to develop a robotically powered unicycle so that we can study the effect of robotic assistance during the development of the skill. The idea is that with this platform, we can answer questions about robotically assisted motor learning that will be useful across many robotic assistance platforms such as exoskeletons.
