Real Time Robotic Motion Planning
The research is motivated by the increasing needs and interests in robots in society and industry, with a goal to significantly advance the computational performance of real-time motion planning of complex robotic systems, such as legged robots. Specifically, we strive to develop massively parallel optimization algorithms and computing hardware to tackle the current computational bottleneck in real-time motion planning of high degree-of-freedom and highly nonlinear robots. This highly interdisciplinary research spans from optimization algorithms to computer hardware, and from mathematical models to robotic systems. The broader impacts of the proposed research stem from its ability to generate theoretical and computational advances in real-time motion planning for a variety of robotic and autonomous systems. Achieving responsive, adaptive motions in a dynamic environment will benefit real-world applications of legged robots, including curbside delivery, planetary science, military and disaster operations, and rehabilitation and medical assistant robotics. Being able to address the real-time motion planning problem in the context of bipeds will also enable inroads into a wide range of robotic platforms, such as robotic manipulators, UAVs, and autonomous driving vehicles.
