Self-navigating, autonomous inspection robot
The system OSSCAR (OnSiteSCAnneR) is a scanner for ultrasound, radar and eddy current sensors. Thus, an inspection area of 0.6 × 1.1 m² can be analysed and a combination of all measurement data in a single graphical representation is possible. The system allows:
� visualization of geometrical elements � localization, determination of the depth and diameter of multilayered reinforcement � localization and depth determination of multilayered tendon ducts � detection of voids and rock pockets
The inspection systems allow the determination of moisture, the detection of voids, rock pockets and cracks, the determination of concrete cover, as well as the determination of corrosion probability of the chlorideinduced corrosion. Even though the application ranges of the two systems overlap to some extent, the primary objective of BetoScan, as an autonomous system, is inspection of large and plane surfaces with a major focus on exchangeable sensor systems, while OSSCAR is used for detailed investigations of small or vertical surfaces.

Situation
For nondestructive inspection of reinforced and prestressed concrete structures a variety of different nondestructive methods were developed, which, in general, are ready for individual use and independent evaluation. The combination of these methods and the accurate representation of the results of all used methods provide outstanding advantages for condition monitoring and damage diagnostics of concrete constructions.
Solution
The inspection robot BetoScan is not only a selfnavigating carrier system for different nondestructive testing sensors. It also allows the automated measuring data recording. The results of the used inspection methods are combined and processed as graphical representation for better condition evaluation.
