EDGE8D

Driver out, computer in

The 2016/17 season is the first season in which vehicles without a driver are on the starting line. The EDGE8 Driverless was developed and constructed precisely for this purpose. The focus of the development was the ability of autonomous operation, which is why the design has remained identical with a few exceptions. The big innovations in the EDGE8 Driverless are the attached speed sensors, cameras and the new laser sensor. In cooperation with our new high-performance computer, the new equipment ensures that surroundings are recognized. As a result, our EDGE8 is now able to maneuver itself through unknown terrain.
