Calibration into component’s coordinate systems

In the case of a manual teach-in or the offline programming of robot programmes, every operating point of the robot concerning the component’s coordinate system is stored. A very common example for this is the vehicle’s coordinate system.

An advantage of this procedure lies in the fact that the operating points of the robot are identical with the construction data of the components.

Offline programming

At graphical CAD stations, the working programmes are drawn up offline. In order to use these programmes inside the real production cell, it is necessary to measure the component’s coordinate system. The measurement provides the mathematic transformation from the component that has to be worked to the base coordinate system of the robot.

Displacement of robots cells

In general, robot cells are first set up, programmed and tested by the producer in his own premises. Only after that, the cells are transported to the ultimate customer where they are finally set up. In order to consider the different positions of the component and the robot as exactly as possible, an additional measurement of the component’s coordinate system will become necessary.
A manual teach-in of the operational points – and with that long unnecessary waiting times until the start-up – may totally be dropped if the measurement of the component’s coordinate system is carried out with the help of our system base:in.

Maintenance

In the case of a crash with component holders, there may be serious displacements, especially if the component holder is a lightweight construction. A quick and automated calibration of the base transformation guarantees a minimum of loss of time in comparison to other common methods.
