Robots/Crawlers

Are there any success stories out there for the use of robots/crawlers to carry out large area inspections on aircraft.

.
The problem is similar to examining the walls of a
nuclear reactor where the steel is non-magnetic. The
clawler has to stick using suction or straps. Such
technology exists for UT and other scans and can be
controlled automatically. Are you looking for a
solution or do you have a solution that you are trying
to promote?

Hello Gary,

As you may know, the Catamaran scanner associated with an AMDATA IntraSpect C-Scan system is a robotic scanner for performing large area inspections on aircraft. It has been used to perform Ultrasonic, Eddy Current and Mechanical Impedance C-Scan testing of aircraft surfaces. It is gantry-like in that its side rails are vacuum mounted and take on the shape of the aircraft. It is capable of doing single sections up to approximately 2 meters wide by 1.3 meters long, or less. Additional 1.3m long tracks can be added to scan as long of a section as you desire. A similar result can also be accomplished through the use of 2 sets of tracks, leap-frogging along as it scans.

For some additional information about the Catamaran scanner, please see our related product release in the Nov 97 NDTnet online journal. That posting can also be found under literature via our Exhibit Stand. If you would like greater detail, we can also provide detailed slides which were presented at the ASNT Fall Conference in 1999.

Thanks,

Regarding your inquiry about Robots and Crawler, you may want to be aware of the ASNT's TONE book series Volume 4, entiteled "Automation, Miniature Robotics and Sensors for Nondestructive Evaluation and Testing." This book comprehensively covers the topic from the robotic and NDE point of views. You can find information about the book thru my website:

Randy,

I believe that the Amdata gantry scanner you describe
was developed for examining aircraft panels. I know
because I designed it for them in 1988 -- unless you
are talking about a similar one designed later.
Combustion Engineering took over and shut down the
office in San Jose shortly after that. I have also
designed many area scan crawlers that can be used
without removing the panels and submerging them in a
tank. There are many ways to do this, but apparently
it is not particularly economical, or else there would
be more systems like that being used on aircraft.
Nuclear NDT budgets are much bigger per scanned area.
