Purpose | Off-road navigation |
RAVON (Robust Autonomous Vehicle for Off-road Navigation) is a robot being developed at the Robotics Research Lab at University of Kaiserslautern, Germany. The vehicle is used, as a testbed to investigate behaviour-based strategies on motion adaptation, localization and navigation in rough outdoor terrain. The basis vehicle was produced by Robosoft.
Description
The vehicle uses a 3D laser scanner.
The vehicle is an example of using behavior-based components on two layers of a multi-layer control system. It also uses a form of short-term memory to prevent collisions with obstacles that it observed some time ago.
The vehicle was experimentally tested at the 2nd Military European Land Robot Trial 2008.
