The Biorobotics Lab reduces complicated high-dimensional problems found in robotics to low-dimensional tractable ones for design, analysis, and planning. Often, we look to biology for inspiration and sometimes, we return the favor by providing analysis that models biology. Our research group runs the full pipeline from basic research, to applied research and all the way to system deployment, and in some cases commercialization. We find that basic theory informs system development and vice-versa. We strongly believe in working with stakeholders in our chosen application fields because they have a unique perspective that challenge our core assumptions, inform future research direction, and drive the development of practical solutions. Our ability to build a great variety of novel field-tested systems stems from advancing modularity, at all levels, both in software and hardware.
