The Spirit of Berlin is an autonomous vehicle that has been designed and built by the Artificial Intelligence Group at Freie Universität Berlin as of 2007. It is a car that can be driven without a driver. A conventional car (Dodge Grand Caravan, 2000) was equipped with sensors, computers, and actuators. The sensors collect information about the immediate environment. Using this information, the software on the computers selects what to do. The resulting action is then implemented with the help of mechanical actuators.

An Ibeo Alasca Laser serves as a wide-range laser. Its 4 separate laser beams allow the detection of obstacles within a range of up to 200 meters off the car, at an angle of 220°. The Sick Laser is a far-range laser with an aperture angle of 120°. At an angle of 20° to the street it's used to detect the curb. We use a camera and algorithms of image pattern recognition to recognize and classify sundry objects and its characteristics. The Velodyne HDL-64E is an omnidirectional laser, involving 64 beams on the top of the car. It rotates at up to 15 Hz. So it's able to detect obstacles within a range of 30 meters, why we use it to control the car's behaviour at crossings. The GPS (Global Positioning System) provides the position determination with a precision of 1m up to 0.1m by using Differential GPS. We separately use an Odometer for calculation of the reclined route. IBEO Laser Sick Laser Camera Velodye Laser GPS GPS GPS Odometer Spirit of Berlin
