Abstract
A height sensorand an image recognizing sectionare installed in a teaching unit; the height sensorcontacts a pinon a load portto detect the height position of the pinand the image recognizing sectionrecognizes a pinand thus its horizontal plane position. A platformof an overhead travelling carriagegrips and lowers the teaching unittoward the load port. The height sensorthen detects the height of the load port. Then, the teaching unitis slightly raised. The horizontal plane position of the pinis recognized and averaged over a time equal to at least the vibration period of the platform. As a result, the position of the load port can be accurately taught to the overhead travelling carriagewithout preparations such as the installation of marks on the load port.
