This article presents the results of a study on including human factors in assessment of the level of danger involved in a robot operation. A dynamic risk assessment method, which considers all effective factors in a collision, is essential for planning and control of the human-safe robots. In this regard, the visibility of the robot in the human eyes can significantly effect the probability of collision...
In this paper a reactive control strategy intended for human-robot interactions (HRI) is presented. A conventional reactive control scheme is reviewed first. This is followed by the introduction of a new prediction-based reactive control strategy. The new control strategy considers foreseeable dangerous events by predicting human motion using artificial neural networks, based on the previous pattern...
Some nonverbal information such as prosody are reported to be able to play a role of penalty signal in human-human and human-agent communication. In order to investigate whether other nonverbal information such as gesture can play similar role in human-robot interactive task, a pilot experiment using a directional guidance task was conducted. The results suggested that a part of ldquostoprdquo instructions...
The objective of this work is first to present a study and analysis of fundamental issues that constitute the development of a hand rehabilitation system by making use of mechanisms for objective and quantitative assessment for patients with motor weakness, such as spinal cord injury (SCI) and post-stroke. The proposed rehabilitation system aims to improve the functional ability of impaired hand on...
