The Grand Challenge
The Grand Challenge is an off-road petition devised by
DARPA (Defense Advanced Research Projects Agency) to promote
research in the area of autonomous vehicles. The challenge
consists of building a robot capable of navigating 131 miles
through desert terrain in less than 10 hours, with no human
intervention.

What the robot need to do?
Globally,
have (either create or buy) a digital map; --mapping
locate its position and orientation on the map; --positioning
find a route to the destination. --route planning
A start and a stop point on a map.
2 hours before the race, a corridor file. 8
The robot must travel inside the corridor.

Elevation Map
A map give a global knowledge to the environment,
While,
A perception to the local surroundings is necessary to provide
accurate control to the robot.
