Main causes of trains delays in Italy (2012)
ANSF - Italian National Agency for the Railway Safety
Railway network maintenance: critical issue for
safety.Lack of maintenance 39% of accidents.
Railroad switches: critical points for derailment.

The first mobile robot for automatic railway switch inspection
Flexibility
• replaces multiple manual tools for
different measures
• used both on railroad switches and on
tracks
Automation
•
analyzes more switches in series• reduces times vs manual survey
Objectivity
• increases accuracy of the measurement
• avoids personnel errors in test plans
Safety • increases safety for operators
• guarantees railways safety
Cost
• cheaper compared to diagnostic
wagons

| NI Labview system design software allowed a rapid prototyping during the
various cycles of product consolidation, shortening the release times. It was alsouseful to create a good looking, intuitive graphical user interface (GUI) for the
field operators.
| NI Vision toolkit was at the basis of the Felix brain, leading to the creation of non
contact measurements algorithms; these have been used for the tridimensional
information extraction from the railway switches.
| Report Generation toolkit was also fundamental to show to the Customers afinal synthesis of the test plans.
| The SW engineering tools (requirement gateway, VI analyzer toolkit, desktop
execution trace, unit test framework) gave a support for the data integrity and
security achievement.
