Abstract: A human-robot interactive system in which a robot and a human share an area for performing interactive work, the human-robot interactive system including a force sensor which is set at an end effector attached to a front end of the robot or which is set at the robot and, when a detected value of the force sensor exceeds a predetermined value, is configured to stop the robot or controlling operation of the robot so that a detected value of the force sensor becomes smaller, the system further including a limiter which limits a work area of said human so as to prevent contact by the human with the first robot portion of the robot that is positioned further from the human than a set position of the force sensor during operation even when the robot approaches the human.

Abstract: A production system in which a human and a robot may simultaneously perform a cooperative task in the same area while ensuring human's safety. A robot is positioned at one side of a working table, and an operator is positioned at the other side of the working table. The reachable area of the operator is limited by the working table. An area of the working table is divided into an area where only the operator may perform a task, an area where only the robot may perform a task, and an area where both the operator and the robot may enter. In a cooperation mode, the maximum movement speed of a component of the robot is limited lower than when the component of the robot is outside the cooperative task area, and, the motion of the robot is limited so that the robot does not enter a robot entry-prohibited area.

Abstract: A force-controlling robot having a function of drawing a fitting part from a receiving part. A fitting part held by a robot hand is moved form an approach start position in a set approach direction under speed and force control. When the fitting part comes in contact with a receiving part and a reaction force thereof exceeds a set threshold value, the fitting part is moved under speed and force control with the set target speed and force and in the set inserting/fitting direction so as to perform fitting. If stoppage occurs before the fitting is completed, the fitting part is moved under speed and force control in the set drawing direction and with the set target drawing speed and drawing force, to draw the fitting part from the receiving part. As the drawing operation is automatically performed, restoration is automatically made without manual operation even if stoppage occurs in the fitting operation. Further, assembled parts can be automatically disassembled.

Abstract: A method and an apparatus capable of accurately measuring the three-dimensional position and orientation of an object in a short data processing time are provided, wherein a first slit light is projected from a first light projector for scanning an object, and each light image is obtained by a CCD camera. Similarly, a second slit light is projected from a second light projector for scanning the object and each light image is obtained by the CCD camera. The first and second slit lights are perpendicular to each other. The individual images obtained are processed to find a bent point and a disconnection point in each slit-light scan image. From among these points, a group of points which are reckoned to be lying on the same straight line is extracted, and the obtained straight line of points is used as edge information of the object. Based on the edge information and shape data of the object, three-dimensional position/orientation data is obtained.
