✦ Synopsis

Trajectory learning is a fundamental component in a robot Programming by Demonstration (PbD) system, where often the very purpose of the demonstration is to teach complex manipulation patterns. However, human demonstrations are inevitably noisy and inconsistent. This paper highlights the trajectory learning component of a PbD system for manipulation tasks encompassing the ability to cluster, select, and approximate human demonstrated trajectories. The proposed technique provides some advantages with respect to alternative approaches and is suitable for learning from both individual and multiple user demonstrations.
