In an emergency, every tractor drives autonomously

Autonomous driving can be the solution if helpers, for example, after a chemical accident or risk of explosion can not dare themselves to the danger. A research network has now developed an autonomy KIT (AKIT) for production-related work vehicles for such scenarios. The AKIT retrofit system, which is installed on the roof of a tractor, for example, includes cameras, laser environment scanners, GPS receivers, communication antennas and a computer unit. The CAN bus system (Controller Area Network) provides direct access to the vehicle functions. This allows the vehicle to drive remotely. In addition, functions such as obstacle detection, route search and autonomous driving are pre-implemented in the computer unit. This allows a tractor to drive autonomously to given GPS coordinates.

All camera images and sensor data come together in the control room, from the excavator to the tractor, but also from an observing drone.

Yesterday, scientists from the Fraunhofer Institute for Optronics, Systems Engineering and Image Evaluation (IOSB), together with the Kerntechnischer Hilfsdienst GmbH (KHG) and other industrial partners, demonstrated their system in Celle. Your scenario: Two autonomous vehicles recover chemical barrels after a train accident. The AKIT was equipped with a Claas tractor and a small excavator. The two unmanned vehicles were accompanied by a drone and a modular transport system, both equipped with camera technology and controlled by a KHG control center. From the control center, the remote control of the tractor and excavator could also be taken over.

"One advantage of the AKIT system is that in the event of an accident not expensive special vehicles have to be brought into the disaster area, only the autonomy KIT," explains project leader Professor Dr. med. Andreas Wenzel, IOSB. With the retrofit system, any conventional construction and work vehicles could ultimately be converted into unmanned and automatic recovery equipment. Before that, however, the technicians would have to set up interfaces to control the machines.

Dast autonomy KIT on the roof of the production vehicle with cameras, laser scanner, computer unit and communication antennas enables autonomous driving and remote control of the vehicle.

In the field demonstration, the excavator and tractor drove autonomously to the scene of the accident, the excavator took a soil sample, then autonomously changed his tool and placed a poison barrel on the trailer of the tractor, which assisted in this scenario. Engineer dr. Janko Petereit, IOSB, emphasizes: "The finding of the barrel, the selection of the gripping strategy and the gripping were also autonomous, and the operator in the control center merely released the test."
