Contemporary examples of autonomous robots exhibit enough intelligence to drive cars in human environments, manipulate objects on assembly lines, and explore distant planets. This performance is however often the result of significant engineering and algorithms that rely on strict simplifying assumptions that fail to extrapolate to more difficult scenarios. Adaptability of planning algorithms to novel tasks and environments is necessary for robots to meet or exceed human performance in domains such as manufacturing, agriculture, and exploration. Two key factors that influence the performance of planning algorithms are the representation of the decision space and the methods for searching it. In this talk, I will discuss my research towards improving the feasibility, optimality, and efficiency of robot decision spaces and present a new probabilistic model for inferring the formulation of robot planning problems from natural language instructions. Throughout the seminar I will highlight applications of my research on planetary rovers, field robots, autonomous automobiles, mobile manipulators, and robotic torsos. The talk will conclude with a presentation of my vision for how the amalgamation of robot planning, natural language understanding, and machine learning will improve the scalability of intelligent cyber-physical systems.
