Abstract
A robot control device includes a position-accuracy-information storage unit that stores position accuracy information at a plurality of division points defined when an operating area space of the multi joint robot is divided into a plurality of areas in a grid shape, a position-accuracy calculation unit that calculates position accuracy at the end-effector position based on the position accuracy information and the current end-effector position of the multi-joint robot, and a position-accuracy output unit that outputs the calculated position accuracy to an outside.
Claims4
A robot control device comprising:
- a storage that stores position accuracy information at a plurality of division points defined when an operating area space of a multi joint robot is divided into a plurality of areas in a grid shape;
- a position-accuracy calculator, connected to the storage, that calculates, based on the position accuracy information and a current end-effector position of the multi-joint robot, position accuracy at the current end-effector position;
- and
- an output, connected to the position-accuracy calculator and to a display, that outputs the calculated position accuracy to the display and also outputs to the display, as a map, a distribution of the position accuracy information stored in the storage, showing regions of at least good accuracy and poor accuracy.
A robot control device comprising:
- a storage that stores position accuracy information at a plurality of division points defined when a joint angle space of a multi joint robot is divided;
- a position-accuracy calculator, connected to the storage, that calculates, based on the position accuracy information and a current joint angle of the multi joint robot, position accuracy at the current joint angle;
- and
- an output, connected to the position-accuracy calculator and to a display, that outputs the calculated position accuracy to the display and also outputs to the display, as a map, a distribution of the position accuracy information stored in the storage, showing regions of at least good accuracy and poor accuracy.
