Abstract:
1. A human-robot interactive system wherein a robot and a human share an area for performing interactive work, said human-robot interactive system comprising: a force sensor which is set at an end effector attached to a front end of said robot or which is set at said robot and, when a detected value of said force sensor exceeds a predetermined value, stopping said robot or controlling operation of said robot so that a detected value of said force sensor becomes smaller, wherein said robot includes a first robot portion which is positioned further from said human than a set position of said force sensor and a second robot portion which is positioned closer to said human than said set position of the force sensor, and wherein said human-robot interactive system is further provided with a limiter that is arranged in a plane which is located between the human and the first robot portion, the plane intersecting with a location of the force sensor of the robot when an arm of the robot is extended in a horizontal direction, which limits a work area of said human so as to prevent contact by said human with said first robot portion of said robot during operation even when said robot most approaches said human.
