Full-Text - AbstractBefore the inspection, manipulator movements are verified using collision detection based on 3-D CAD models of the inspected item as well as the actual manipulator. This process revealed problems covering the areas 100 % with the first lamp design proposal. After redesign, the system could cover the surfaces as planned.
OEM camera blocks with 8 to 12 times zoom from Sony was build into a splash proof housing with connectors for the S-VHS signal, power supply and RS232 communication. The housing allows mounting of standard camera filters and external lamps. A PC program allow remote control of Zoom, focus (also activation of autofocus), colour temperature etc. The PC interface can easily be adapted to the actual application. The camera control was integrated into the manipulator control system. This gives the operator a consistent user interface for the complete inspection system. The visual examination system can be remote controlled from a distance of at least 100 meters. Digital images can be stored on disk either manually or automatically for each manipulator position.
Additional mini cameras and light sources were mounted for surveillance of the manipulator movements.
A video will show how the visual examination takes place in a main re-circulation pump housing. The manipulator is designed for a low radiation level environment as the system was decontaminated.
