Center node: "A model of distributional handing interaction for a mobile robot"
  Abstract: This paper reports our research on developing a model for a robot distributing flyers to pedestrians. The difficulty is that potential receivers are pedestrians who are not necessarily cooperative; thus, the robot needs to appropriately plan its motion, making it is easy and non-obstructive for potential receivers to receive the flyers. In order to establish the model, we observed human interactions on distributional handing in the real world. We analyzed and evaluated different handing methods that people perform, and established a model for a robot to perform natural handing. The proposed model is implemented into a humanoid robot and is confirmed as effective in a field experimen
