- W2890882989 abstract "Continuous-time trajectories are useful for reasoning about robot motion in a wide range of tasks. Sparse Gaussian processes (GPs) can be used as a non-parametric representation for trajectory distributions that enables fast trajectory optimization by sparse GP regression. However, most previous approaches that utilize sparse GPs for trajectory optimization are limited by the fact that the robot state is represented in vector space. In this paper, we first extend previous works to consider the state on general matrix Lie groups by applying a constant-velocity prior and defining locally linear GPs. Next, we discuss how sparse GPs on Lie groups provide a unified continuous-time framework for trajectory optimization for solving a number of robotics problems including state estimation and motion planning. Finally, we demonstrate and evaluate our approach on several different estimation and motion planning tasks with both synthetic and real-world experiments." @default.
