|Because they are regularly subjected to heavy vehicle traffic, emissions,
moisture and salt, above- and underground parking garages, as well as
bridges, frequently experience large areas of corrosion. Most inspection
systems to date have only been capable of inspecting smaller surface
areas. From April 13 to April 17 at the Hannover Messe (hall 2, exhibit
booth C16), engineers from the Fraunhofer Institute for Nondestructive
Testing IZFP will be presenting BetoScan®, a robot capable of inspecting
concrete surfaces as large as several hundred square meters on its own.
Only one person is required to operate and monitor the system.
Employees from the Fraunhofer Institute for Nondestructive Testing IZFP, together with
the German Federal Institute for Materials Research and Testing (BAM) and industry
experts, have joined forces to develop a robot platform that can independently scan
and inspect large areas of concrete for damage without impacting the surface.
Referred to as BetoScan®, the system was designed as a self-propelled, self-navigating
robot platform for nondestructive inspection sensors.
"Our robot can easily inspect parking garage surfaces as large as several hundred
square meters in one day and requires only one person to operate and monitor the
system," explains Ralf Moryson, an engineer at Fraunhofer IZFP. The robot can
independently scan obstacle-free concrete surfaces using a preselected grid while
simultaneously recording the data acquired by the various inspection processes. The
cascadable mounting system for the inspection sensors permits the utilization and
quick replacement of commercially-available sensors. When selecting the sensors for
the system, the developers focused on automated logging of the measurement results,
as well as on the use of well-established inspection methods. This provides an extensive
inspection capability that ensures the timely identification of surface corrosion. While
scanning the surface, the system also creates a survey of the structure being inspected.
"A major advantage of our robot system is the integrated combination of different
nondestructive testing processes. The sensors analyze factors such as moisture content
and the thickness of the concrete, as well as the depth and condition of the
reinforcement," adds Moryson. The complete measurement results can be graphically
displayed. Rounding out this development is the ability to administer the measurement
The BetoScan® project was funded through the German Federal Ministry for Economic
Affairs and Energy InnoNet program.
