Enhancing Mobility Using Innovative Technologies and Highly Flexible Autonomous Vehicles

Abstract

The combination of automobiles and typical robotic technologies such as high computational power, advanced exteroceptive sensors, and complex control algorithms can lead to a new kind of mobility. Features like extended maneuverability, autonomous driving systems, and new safety features become imaginable. To create the best combination of both fields, a new design philosophy is required. At DFKI, we have developed two generations of innovative concept cars (EO smart connecting car 1 and 2) with the intention to build the bridge between robotics and cars. The development of key parts like suspension, drivetrain, electrical steering, and braking system is more interconnected than in conventional vehicles. In this paper, we describe the development process of EO smart connecting car 2 - a highly innovative and fully functional robotic electric vehicle XE "electric vehicle" with double Ackermann steering, the ability to turn on the spot, go sideways, drive diagonally, change ride height, and shrink by adjusting the position of its rear axle and tilting the cabin as well as docking at charging stations and extension modules. Detailed information of the utilization of Rapid Control Prototyping, and optimization strategies will be given as well as the design constraints for these technologies. Finally, the conclusion section will cover problems and challenges that had to be overcome and future work that will follow.
