Generation of a Task Model by Integrating Multiple Observations of Human Demonstrations
This paper describes a new approach on how to teach a robot everyday manipulation tasks under the “Learning from Observation” framework. Most of the approaches so far assume that a demonstration can be well understood from a single demonstration. But a single demonstration contains ambiguity, in that interactions which are essential to complete a task can’t be discerned without prior task dependent knowledge, which should be obtained from observation. To address these issues, we propose a technique to integrate multiple observations of demonstrations. The demonstrations differ, but are virtually a same task. The shared interactions among all the demonstrations are considered to be essential and we form a task model from their symbolic representations. Then the relative trajectories corresponding to each essential interaction are generalized by calculating their mean and variance and are also stored in the task model, which is used to reproduce a skilled behavior. We examine this...
