Industrial robots are often equipped with external sensors that help perform the required production tasks. These sensors may be optical, tactile or force-torque sensors. Depending on the sensor, the measuring range can cover a one-dimensional, two-dimensional or threedimensional space. More specifically, laser line sensors are often used for inspection and calibration of 3D objects. Implementing an intuitive calibration method of such sensors on the robot flange is a challenging task. This is due to the fact that robotic applications and measurements are usually implemented with the presence of noise. As a result, best-fit methods or filters are implemented in order to realize an effective usage of the sensors. This paper deals with the concept of calibrating laser line sensors in order to measure cylindrical components using a bestfit method. Moreover, a modular control system for configuration and operation of the station with a variety of interfaces is discussed.
