1. What are the contributions in this paper?
Imitation learning has been studied widely as a convenient way to transfer human skills to robots.. In this paper, the authors propose a novel kernelized movement primitive ( KMP ), which allows the robot to adapt the learned motor skills and fulfill a variety of additional constraints arising over the course of a task.. Moreover, the authors extend their approach by exploiting local trajectory representations in different coordinate systems that describe the task at hand, endowing KMP with reliable extrapolation capabilities in broader domains.. The authors apply KMP to the learning of time-driven trajectories as a special case, where a compact parametric representation describing a trajectory and its first-order derivative is utilized.. In order to verify the effectiveness of their method, several examples of trajectory modulations and extrapolations associated with time inputs, as well as trajectory adaptations with high-dimensional inputs are provided.
