ultimately enable major design and process changes
creating the opportunity for considerable cost savings for
the aerospace industry. Future structures could be
designed with fewer and smaller access panels and
maintenance times could be reduced.
This paper presents early stage results of the
demonstration snake-arm robot and outlines
expectations for future development. The paper
identifies critical design parameters for the snake-arm
and considers the tools and processes to be delivered
by the snake-arm.

How does it work?
Operating Modes
CVM
Continuous Periodic
Monitor Switch
More efficient Testing More efficient NDI
•Complex networks
•Real time monitoring •Automatic control •Less strip / rebuild

Military Aircraft
Airbus JDA
Boeing NDT SPM
•2006: CVM included in Standard Practice Manual
•2007: CVM as AMOC for several SB 737inspections
CV Switch
•Quality control testing
•Developmental testing
•Small Crack detected in real time
•Appropriate action automated
- test stopped
- alarm (light/sound) triggered
- signal sent
Quicker, More Accurate, Less labor intensive testing
