US 12,257,720 B2 · Robot control device

Abstract

The purpose of the present invention is to eliminate the need, when a robot has been replaced with a new robot that is different in size, for an operator to directly re-input as operation program to make the robot operative. This robot control device comprises: a storage unit that stores an operation program; and a control unit that operates a robot is a robot coordinate system with three orthogonal axes. The control unit is provided with: a mobility range determination unit that determines whether there is, in the operation program, an axis, among the three orthogonal axes, that exceeds a mobility range of the robot; and a correction unit that, if it has been determined by the mobility range determination unit that there is an axis that exceeds the mobility range of the robot, rewrites the operation program so the axis is kept within the mobility range of the robot.

Dependent claims

A robot control device comprising:

a control unit that operates a robot on a robot coordinate system with three orthogonal axes according to an operation program;
and
a storage unit that stores a first operation program for a first robot, wherein
the control unit includes:
a mobility range determination unit that determines, in the first operation program read from the storage unit, whether there is an axis exceeding a mobility range of a second robot that is different in size from the first robot among the three orthogonal axes;
and
a modification unit that, when determined by the mobility range determination unit that there is an axis exceeding the mobility range of the second robot, rewrites the first operation program such that the axis comes within the mobility range of the second robot.
