Problems solved by technology

Such conflicts can result in damage that interrupts production and repairs can also be costly
Furthermore, lengthy engineering and programming efforts must be repeated for each new work object to be addressed
Also, a problem that can occur with robotic automation, such as in the case of a conveyor belt production line, is that each robot must be individually inspected and / or manually operated or "nudged" to the point where the conveyor belt stops and a shutdown occurs. known or "original" location
This problem, and possible conflicts, often results in scrap or unacceptable quality; or loss of production; or both

Embodiment Construction

[0027] Figure 1 (Prior Art) shows a method of teaching a task to one or more robots according to known methods. To establish a new or changed job, a series of the first 4 of the following 5 stages or steps are repeated until a satisfactory production result is achieved. These steps are:

[0028] - design of the communication concept between the robot and the controller,

[0029] - developing a movement program for each robot and teaching said program to each robot,

[0030] - Coordinate testing, move adjustments, repeat testing until satisfied,

[0031] - exception handling routine, test recovery routine, repeat until satisfied,

[0032]- Start production.

[0033] figure 2 A method for teaching a task to one or more robots according to an embodiment of the invention for controlling one or more robots is summarized. It is immediately apparent how quickly pre-production changes and installations can be made by utilizing this method. The schematic diagram shows that the u...

Abstract

A method, controller and control system for controlling a robot that is used in concert with at least one other robot to perform an operation on one or more work objects. Each robot controller checks whether a common reference value is not acceptable, and if so, provides a signal for the robot to wait before proceeding to the next task. Each robot controller also checks whether the target object is in the correct position or not; and also checks whether or not another robot has stopped. If either another robot has stopped and / or if the work object is not in the right position, the robot waits.

Description

technical field [0001] The present invention relates to control methods, devices and systems for industrial robots or manipulators. In particular, the invention relates to robotic installations or applications comprising at least two industrial robots, wherein at least one industrial robot comprises at least four axes for servo-controlled movement. An industrial robot in this specification includes a manipulator having an electric motor, a control mechanism including a power mechanism for driving the motor, and a computer mechanism arranged to sense by instructions from a computer program. Measuring and controlling the movement of the manipulator. Background technique [0002] Industrial robots are used to quickly and precisely perform a large number of industrial and / or commercial tasks. In many applications, such as welding car bodies or painting cars, robots must manipulate tools such as arc welding tips, paint sprayers or grippers with consistent precision and speed to...
