Prof. Bretl develops tools for motion analysis, planning, and control. These tools include geometric search algorithms, methods of model reduction, and convex optimization routines that take advantage of problem structure. He is applying these tools to a diverse set of mechanical and biological systems: legged robots for planetary exploration, autonomous sail-planes for atmospheric and environmental science, neuro-prosthetic devices with a control interface designed using biological principles, and robotic manipulators for intelligent machining of deformable objects. All of these applications are safety-critical, so there is a strong emphasis on trust: tools must be practical, be easy to implement, and have verifiable performance guarantees.
