Curious optimization

Artificial intelligence (AI) is getting increasingly good at learning, but learning is a distinct concept from being curious. When you learn, you sit back and absorb what's happening. When you're curious, you act in ways to explore your world. We're developing numerically efficient ways to enable curious optimization and AI. Our preliminary results demonstrate that enabling numerically efficient curious optimization results in better, long-term results across a variety of contexts ranging from industrial processes to healthcare and public policy.

Improving control of prosthetic limbs

People are pretty smart. Prosthesis control signals are noisy. Existing control interfaces don't really take either of these facts into account. Computational motor control is a promising approach to understanding how people control their limbs that can account both for the intelligence of people and the uncertainty of their available control signals. We are applying it to prosthesis control with the hope that if we can accurately model people-in-the-loop for existing control strategies, we can then use our model to evolve better control strategies that harness the intelligence of people and minimize the effect of signal uncertainty on performance.

Archived: Exoskeleton and lower-limb prosthesis design and control

Design and control of exoskeletons and lower-limb prostheses are challenging in different ways than upper-limb devices: walking can be thought of as the art of continuously falling, so designing human-like control strategies that enable walking and yet gaurantee stability is a challenging goal. We've designed and tested control strategies that achieve this goal, tested them with end-users, and patented several of our strategies and designs.

Archived: Myoelectric prosthesis design

By spending time understanding the clinical needs of people who choose not to use a prosthesis, and by digging deep into the theory of motor and transmission theory, we developed a small yet powerful prosthetic arm that was tested in field trials. Components were licensed to several commercial companies.

Archived: Body powered prosthesis design

Body-powered prostheses are lightweight, rugged and have an amazing amount of fine control and natural sensory feedback due to the cables that link them to the shoulder harness. Unfortunately, cables can only pull, so devices have to be spring-loaded: either open or closed. There are pros and cons to both approachs depending on the situation. We explored designs that made it easy to switch between these two modes without having to adjust the slack in the cable, and tested the device in a field trial.
