Provided is a method, device, and computer-readable medium for controlling a robot graphic user interface (RGUI) on a mobile device. The method can include determining a distance, a position, or both of the mobile device with respect to a first robot; and causing, by a processor, a first RGUI to be displayed on a display of the mobile device based on the determining.

A robot controller having a function that simplifies learning and a robot control method. The robot controller includes: a learning section configured to carry out learning of detecting a deviation between a commanded trajectory representing a position of the robot generated according to the command values and an operation trajectory representing an actual position where the robot has moved, and generate a corrected program by adjusting the commanded trajectory; a saving section configured to save the corrected program; and a relearning section configured to carry out relearning on a relearning location, the relearning location being a part of the operation trajectory designated by an operator.

A robot control device executes assist control for generating an assist force in a direction of an external force applied to a robot in a case where a position of the robot is located in a first area set in a work area of the robot when the external force is applied to the robot. The robot control device stops the execution of the assist control in a case where the position of the robot is located in a second area set outside the work area of the robot. The robot control device restricts the execution of the assist control in a case where the position of the robot is located in a third area set outside the first area and inside the second area.

A robot system comprises a robot provided with a robot arm and a robot hand, and a control device for controlling the motion of the robot, wherein a permitted area where a teaching operation for the robot hand should be permitted is preset within a maximum area which the robot hand can reach. The control device is provided with a judging part which judges if the robot hand as a whole is present in the permitted area, based on robot hand position information, and a teaching operation restricting part which permits a teaching operation for the robot hand when it is judged that the robot hand as a whole is present in the permitted area and prohibits a teaching operation for the robot hand when it is judged that the robot hand as a whole is not present in the permitted area.
