Workspace analysis for planning human-robot interaction tasks

摘要

We present an approach for determining suitable locations for human-robot interaction tasks. Therefore, we introduce the task specific Interaction Workspace as a representation of the workspace that can be accessed by both agents, i.e. the robot and the human. We show how the Interaction Workspace can be efficiently determined for a specific situation by making use of precomputed workspace representations of robot and human. By considering several quality measures related to dexterity and comfort, the Interaction Workspace provides valuable information about potential targets for human robot interaction (e.g. for object handover tasks). We evaluate the online performance of building appropriate data structures and show how the approach can be applied in a realistic hand-over use case with the humanoid robot ARMAR-III.
