A control device controls a robot and an articulated shaft of the robot, the articulated shaft being attached to the distal end of an arm of the robot. The control device includes an operation program analysis unit that calculates a movable range of a combination of the robot and articulated shaft based on an operation program, and a robot/tool moving distance calculation unit that, based on the calculated movable range, sets an amount of movement of the articulated shaft for moving the articulated shaft to a boundary position as a specified value, and calculates the amount of movement of the distal end of the arm when the articulated shaft is moved to the boundary position, and the amounts of movement of the articulated shaft and the distal end of the arm of the robot for at least one teaching point other than the boundary position.

Control device and control method

A lifetime estimation device for a robot including a linear-motion mechanism including a guide member and at least one slider moving along the guide member includes: a load calculation unit that calculates, at predetermined time intervals, a load acting on each slider on a basis of a program for operating the robot and geometric parameters of the robot and a load mounted on the robot; a travel-distance calculation unit that calculates travel distances of the slider at the time intervals; a lifetime calculation unit that calculates a lifetime of the linear-motion mechanism on a basis of the loads calculated by the load calculation unit and the travel distances calculated by the travel-distance calculation unit; and a display unit that displays the calculated lifetime.
