3. Locator UR Cap Setup

The Locator UR Interface is available as an URCap and three basic program templates. All of these files need to be copied to the Robot Controller.

As the first step, URCap needs to be installed. Extract the Locator URCap archive (.zip file) to the USB stick and plug it into the Teach Pendant.

Press Menu -> System -> URCaps:

4. Calibration

Robot Camera Calibration is a crucial step in Locator configuration. Accurate calibration guarantees that object positions will be calculated directly in Robot Base coordinates.

4.1 Robot - Camera Calibration

Mount the Scanner firmly, ensure that the scene is properly captured from the final position and open the LocatorCalibration program:

Locator Calibration interface consists of three URScript functions:

  • - calibration_start(scanner_id, ball_radius) - this procedure needs to be called at the beginning of the calibration program
  • - calibration_add_point() -
  • - calibration_finish()
