Abstract
The market of Human-Symbiotic-Robots that share active area with humans is growing. However, safety standards JIS and ISO for Human-Symbiotic-Robots are not provided yet. And, the risk assessment to them is difficult. In this paper, we propose a new technique of risk estimation of Human-Symbiotic-Robots that work like as humans. We measure movement histories of the human that is assumed to be Human-Symbiotic-Robot works in shared space. Then, we propose to estimate the risk based by the movement histories.
