Patent ID: 8423185

Claim:
A robot system, comprising: a plurality of robots each having a first parameter and a second parameter, the first parameters of the robots having a parameter type same as one another, the second parameters of the robots having a parameter type same as one another and different from the parameter type of the first parameters; a robot teaching device configured to teach and operate the robots, the robot teaching device including a display and an operation device, the display being configured to display the first parameter corresponding to one of the robots, the operation device being configured to be operated by an operator to change the first parameter displayed in the display from the first parameter corresponding to one of the robots to the first parameter corresponding to another of the robots, the operation device being configured to be operated by the operator to change a value of the first parameter displayed in the display; and a robot control device connected to the robots and the robot teaching device, the robot control device being configured to control the robots based on the first parameters, the robot control device selecting, if the operating device is operated by the operator to change the first parameter displayed in the display from the first parameter corresponding to one of the robots to the first parameter of another of the robots, a robot corresponding to the first parameter newly displayed in the display from among the robots as an operational object, wherein the robot control device is configured to control the robots based on the second parameters, wherein the display includes an all-purpose area including a first sub-area and a second sub-area, the first sub-area being configured to display the first parameter of one of the robots, the second sub-area being configured to display the second parameter of one of the robots, wherein the operation device is configured to be operated by the operator to select an active area from among the first and second sub-areas, wherein the robot control device is configured to detect the active area selected by the operator using the operation device, wherein the robot control device compares a robot corresponding to the first parameter displayed in the first sub-area with a robot corresponding to the second parameter displayed in the second sub-area if the active area is changed from the second sub-area to the first sub-area, and wherein the robot control device changes the operational object from the robot corresponding to the second parameter displayed in the second sub-area to the robot corresponding to the first parameter displayed in the first sub-area if the robot corresponding to the first parameter displayed in the first sub-area is different from the robot corresponding to the second parameter displayed in the second sub-area.
