摘要
One of the most important characteristics that needs to be taken into account while designing advanced human-robot interaction systems is the ability of the robot to behave in a socially acceptable way that is comfortable for humans. This paper presents a novel system for robot to human object handover that maximizes user%26apos;s convenience while receiving the object. The object is delivered to the receiving partner such that the most appropriate part is oriented towards him/her. The system has been developed supporting all the necessary phases of the handover task, including object recognition, people detection, robot motion planning, and automatic detection of user%26apos;s grasp. Moreover, voice recognition and text-to-speech have been integrated to enable natural object selection in environments that include multiple objects. The experimental setup consists of a six degree of freedom robot arm equipped with a two-finger gripper and an eye-in-hand laser scanner for object recognition, as well as a fixed range sensor for people and grasp detection. A user study has been conducted to assess the usability of the system and verify whether novice users can successfully accomplish a handover task with the system. The user study has confirmed that the proposed solution allows a more comfortable handover than a system disregarding object orientation.
