A robot movement programming method and apparatus for effectively creating a program for operating a robot with respect to workpieces of identical or similar shape. Sample programs for specifying sequence patterns suitable for the robot operations to be carried out are prepared, and also conversion formulas for obtaining teaching point position data are prepared as functions of dimensional parameters. The sample programs and the conversion formulas associated therewith are registered in a pattern library. The operator selects from the pattern library a sample program representing the sequence pattern suited for the robot operation to be carried out and designates the sample program as a base for creating a robot movement program after editing it, if necessary. Then, the operator inputs various parameter values, watching a graphic image of the sequence pattern specified by the selected sample program. A personal computer calculates necessary teaching point position data according to the conversion formulas and creates a robot movement program based on the calculated teaching point position data.

Programming method and apparatus for robot movement

An robot control apparatus with a teaching operation panel capable of making graphic display. The teaching operation panel comprises a processor, a flash memory, a DRAM, a communication port, a touch panel, a graphic controller for controlling a display device, a key control circuit for jog keys. The flash memory stores an operating system having small data size storable in the flash memory and supporting a graphic interface. The processor reads a robot operation program stored in a memory of the robot controller or in an external memory of the teaching operation pane and makes a graphic display on the display device. The graphic display is easily comprehended by an operator and editing and creation of the robot control program is made easy.

Jog feeding method for robots

Teaching pendant for a robot

While jog feeding, if the robot can be moved safely without interference or collision with others, the data on jog feeding path is accumulated in an external memory device. And a safe region in which the robot can move without interference or collision can make from some accumulated paths in the robot axial space and stored. When start point and end point for the desired path are specified, one path, which links the start point and the end point and is composed of such safe regions, is found. Then the robot positions are taught as positions corresponding to the path.

Robot teaching method

Robot control apparatus and method eliminating any influence of motion

A robot position teaching system and method including a robot controller to control a robot, a visual sensor to measure a three-dimensional position, an image processing device to measure a position by processing and analyzing an image recognized by the visual sensor, and a position teaching unit provided with a grasping portion having a size which can be grasped by a hand of an operator, and an index which can visually be recognized by the visual sensor, and is disposed at a distal end of a rod-type body extending from the grasping portion. The operator turns on a moving switch of the position teaching unit such that the robot controller moves the robot toward a position of the index recognized by a camera. When an approach teaching switch of the position teaching unit is turned on after movement of the robot is stopped, data of a current position of the index recognized by the camera is stored as teaching position data. On the other hand, by turning on an arrival teaching switch, a current position of the robot is stored as the teaching position data.
