thus increasing the protection of the sensor head. This feature can also be useful in the early phase of the process planning as the scanning time of a full set of work-pieces could be measured by means of an offline simulation. Obviously, a robot connected to the computer can be directly manipulated by using the desired path. For special purposes, a motion tracking system has also been implemented which ensures the direct control of the robotic arm by defining the joint position or by
transmitting the tool position and orientation.
