Abstract

A robot program checking method for editing a robot program accurately and rapidly. When types of a controller and a robot body to which an edit program is to be applied are specified after the edit program is created, a format table indicative of a format suitable for the controller and movable range data for an operating section of the robot body are transferred from a floppy disk to a working memory together with the edit program. If the edit program which is read out one block by one block is not stated in accordance with a predetermined format, or if a position data contained in the edit program and indicative of a target moving position of the operating section of the robot body falls outside the movable range, an error message indicative of a block number and a reason for the error are printed out. With reference to the error message, an operator corrects the edit program.

Claims5

Dependent claims

A robot program checking method, comprising the steps of:

(a) storing beforehand a format suitable for a controller of the robot;
(b) storing beforehand a movable range of an operating section of a body of the robot;
(c) reading out an edit program;
(d) determining whether or not the thus read edit program is stated in accordance with the format suitable for the controller of the robot to which said edit program is to be applied;
(e) when a read block contains data indicative of a target operating position of the operating section of the robot body, determining whether or not said data falls within the movable range of the operating section of the robot body of the robot to which said edit program is to be applied;
and
(f) generating an alarm when results of determination in said steps (d) and (e) indicate that the format of the edit program is not suitable for the controller to which the edit program is to be applied, or the position data contained in the edit program falls outside the movable range of the robot body.
