An industrial robot continuously and automatically executes a teaching step of learning a hand position that is the position of a hand when mounting a transported object to be placed in a predetermined position on a placing section, and a calibration step of correcting the hand position learned in the teaching step. In the calibration step, the hand is moved to the hand position identified in the teaching step, and a transported object for teaching placed in the predetermined position is mounted and taken out onto the hand. Thereafter, the hand is moved again to the hand position identified in the teaching step and the transported object for teaching is placed on the placing section. Afterward, the position of the transported object for teaching is detected by second sensors attached to the hand and the hand position is corrected based on the detection result by the second sensors.

Industrial robot and teaching method for industrial robot

A robot system includes a robot controller and an object robot including a first storage part storing a hardware identifier, individual discrimination data, and device specific data including an individual difference parameter. The same hardware identifier is assigned to the object robot having the same mechanism. The robot controller includes a second storage part storing common configuration information corresponding to the hardware identifier and the individual discrimination data and the individual difference parameter of the object robot, and a control part configured, in a case that the hardware identifier corresponding to the common configuration information stored in the second storage part and the hardware identifier assigned to the object robot are collated and matched with each other, to create hardware definition information of the object robot based on the common configuration information stored in the second storage part and the individual difference parameter read from the first storage part.

Robot system

A robot may include a base; a base link connected to the base; an arm link coupled to the base link; an arm connected to the arm link; a hand connected to the arm; a storage; and a controller. The base link and arm link move so that a center of a coupling shaft of the arm link and the arm moves in a line. When the robot is within a predetermined range of a latest coordinate, the robot moves to the return-to-origin position in a direction from the transfer direction, otherwise the controller calculates the transfer path based on past teaching, and determines if there is a path close to the latest coordinate. If there is path, the controller determines whether the hand section is outside of a safe area, and if so, pulls the hand to a safe area and then moves the robot to the return-to-origin position.

Horizontal articulated robot and return-to-origin method thereof

A robot system may include a robot controller; and a target robot. The target robot may include a first memory to store device specific data including individual identification data; and an individual difference parameter unique to the target robot. The robot controller may include a second memory structured to store the individual identification data and the individual difference parameter of the target robot connected to the robot controller; and a controller to control the target robot on the basis of model configuration information the individual difference parameter stored in the second memory. The controller may check the individual identification data read from the first memory unit against the individual identification data stored in the second memory unit and, in accordance with a checking result, update the individual difference parameter stored in the second memory unit with the individual difference parameter read from the first memory unit.

A robot system may include a robot controller; a target robot; and a host device. The target robot may include a first memory to store device specific data comprising information on the model of the target robot; individual identification data used to identify the target robot; and an individual difference parameter unique to the target robot. The robot controller may include a second memory to store information on the model of the target robot connected to the robot controller, the model configuration information, the individual identification data, and the individual difference parameter; and a controller to control the target robot on the basis of the model configuration information and the individual difference parameter stored in the second memory unit. The controller may read the model configuration information of the model and store the model configuration information in the second memory unit.

A work transfer system may include cassettes to house a work; a processing apparatus; and a robot to load and unload the work. The robot may include a base, a base link connected to the base, an arm link coupled to the base link, an arm connected to the arm link, and a hand connected to the arm. The base link and the arm link are controlled so that a center a coupling shaft of the arm link and the arm moves along a straight line. The cassettes are parallel to the straight line. A via point is specified for each quadrant of coordinate system and the robot moves between stages that are a target of loading or unloading of the work and uses the via point as a via point when moving.

Work transfer system and control method thereof

A teaching method for an industrial robot may include, while the hand is lifted up and down by the lifting mechanism, detecting, with the first sensor, a position of either the installation unit or a teaching jig to be installed on the installation unit in a vertical direction; while the hand is transferred in the first direction by the transfer mechanism, detecting, with the first sensor, a position of either the installation unit or the teaching jig in the first direction; while the hand is transferred in the first direction by the transfer mechanism, detecting, with the second sensor, a position of either the installation unit or the teaching jig in the first direction; and calculating a position of either the installation unit or the teaching jig in the second direction, in order to teach a position of the transfer object to be installed on the installation unit.
