Abstract: A robot control system including a robot controller configured to control a robot, two operation devices configured to manually operate the robot, the first operation device being connected to the robot controller. Each of the operation devices has a request switch configured to switch between a request state in which an operation right for the robot is requested and a non-request state in which the operation right is not requested, and the robot controller is configured to start providing the operation right to one of the operation devices only when the request switch of the one of the operation devices is in the request state and the request switch of the other of the operation devices is in the non-request state, and keep the operation right granted until the request switch of the one of the operation devices is switched to the non-request state.

Abstract: A machining control system includes: a numerical control device controlling a machine tool; and a robot control device communicating with the numerical control device and controlling a robot having a plurality of drive axes. The numerical control device includes: a coordinate position command generation unit generating a coordinate position command specifying a target coordinate position at each time of a leading end part of the robot, based on a machining program; and a communication unit sending the current target coordinate position to the robot control device. The robot control device includes: a target drive position calculation unit calculating a target drive position of each of the plurality of drive axes to position the leading end part at the target coordinate position; and a drive command generation unit generating a drive command to each of the drive axes to position the drive axes at the calculated target drive position.

Abstract: A robot teaching system includes a hand guide unit including a stick for use in a teaching operation of a robot, and a wireless communication unit configured to communicate by radio with a teach pendant; a relative position setting unit configured to set relative position information between the hand guide unit and the robot; and a coordinate calculation unit configured to calculate, based on the relative position information, coordinates having as an origin a flange surface of the robot or a distal end point of a tool attached to the robot, in such a manner as to correspond to an operation direction of the stick.

Abstract: To provide a robot system capable of ensuring safety while giving consideration to the occurrence of a trouble in image capture means. A robot system with a camera for monitoring a robot comprises: current position model generation means that generates a current position model for the robot based on current position data about the robot and robot model data about the robot; simulation image generation means that generates a simulation image of the robot viewed from the direction of the camera based on set position data about the camera, set position data about the robot, and the current position model; detection means that compares the simulation image and a monitoring image acquired from the camera to detect the robot in the monitoring image; and safety ensuring means that ensures the safety of the robot system if the detection means does not detect the robot in the monitoring image.

Abstract: A system for detecting and displaying an external force applied to a robot. Magnitude and direction of the detected external force are displayed by an image for visual and intuitive understanding. A robot system includes a robot; a detection section for detecting an external force applied to the robot; a conversion section for converting magnitude and direction of the external force detected by the detection section into a coordinate value of a three-dimensional rectangular coordinate system; an image generating section for generating a force model image representing the magnitude and direction of the external force by a graphic, with use of the coordinate value obtained by the conversion section; and a display section for three-dimensionally displaying the force model image generated by the image generating section.

Abstract: A robot system including: a robot and a controller, the controller is configured to conduct: a region generating process that generates a robot inclusion region which includes the robot and the like and whose area increases as a speed of the robot increases, an entry prohibited region near the robot, and a speed limit region along the robot side edge of the entry prohibited region; an entry detecting process that detects whether or not the generated robot inclusion region enters the entry prohibited region or the speed limit region; a speed limiting process that reduces operating speed of the robot if the robot inclusion region enters the speed limit region; and a power cutoff unit that immediately stops the robot if the robot inclusion region enters the entry prohibited region.

Abstract: A production system includes a robot, a robot controller, and a person detection part. The controller includes first speed comparison unit that has the function of activating a power cutoff unit so as to stop an operation of the robot when a current speed exceeds a predetermined reference speed; and an external-force comparison unit that has the function of activating the power cutoff unit so as to stop the operation of the robot when a current force applied to the robot exceeds a predetermined reference force. The controller disables the functions of the first speed comparison unit and the external-force comparison unit while the person detection part detects the absence of the operator in the cooperative operation space.
