Robot center-of-gravity display device, robot control device, and robot simulation device

A robot center-of-gravity display device comprising:

• a specification setting unit that sets the specifications including, at least, the weights, center-of-gravity positions, and dimensions of components of respective shafts of a robot;
• a posture setting unit that sets position information of the respective shafts of the robot;
• a robot-image generating unit that generates a three-dimensional model image of the robot in a state in which the respective shafts thereof are located at the positions indicated by the position information based on the position information of the respective shafts of the robot set by the posture setting unit and the specifications of the components set by the specification setting unit;
• a center-of-gravity-position calculation unit that calculates the center-of-gravity position of the overall robot based on the position information of the respective shafts of the robot set by the posture setting unit and the specifications of the components set by the specification setting unit;
• an image combining unit that superimposes an indication showing the center of gravity of the overall robot on the three-dimensional model image generated by the robot-image generating unit, at the center-of-gravity position calculated by the center-of-gravity-position calculation unit;
• and
• a display unit that displays the image generated by the image combining unit.
