EOscc2 - An ultra flexible micro-car for mega-citiesMore and more people are drawn into the big cities of the world. Consequently, all of these cities have one challenge to face: Not enough parking space and very congested traffic, especially during rushhours. This becomes even more problematic when big cars are just used by single individuals.
Therefore, small, comfortable and safe cars are required and, in addition to that, the electric drive train provides possibilities to completely rethink what we know about individual transportation.
EO smart connecting car 2 is the result of consequent and ongoing research, development, and optimization of the EO smart connecting car concept.
Like its predecessor, it features
- normal driving
- driving diagonal
- turning on the spot
- even driving sideways
- and shrinking from ca. 2.6 m down to ca. 1.8 m
- while maintaining a comfortable seating position.
Big windows guarantee a good perception of the surrounding environment while an intuitive user interface provides easy access to all drive modes the robotic car has to offer.
Moreover, the car’s computer and its auto-navigation system provides extensive driver assistance functions. Autonomous parking, even within narrow and congested roads, is possible. Later, an autopilot will be able to drive the car without a single passenger intervention creating the driverless car.
Designing a possible future of mobilityA team of nine engineers and a designer as well as several students created the robotic car between Oct. 2011 and Jul. 2014. To prove the feasibility of the technical requirements an integration study as well as a detailed physics simulation model was built. Both utilized the final axial modules and most of the final electronic components but was controlled by a “Rapid Control Prototyping” system.
After successful testing a chassis was constructed and built. At the same time, software development was underway for highly integrated, dedicated, and custom built vehicle control units.
One problematic aspect of electric vehicles is the charging cable. To face this issue, a versatile, foldable docking interface was constructed that fits into the body of the car and also allows for connecting extension modules, like range extenders, passenger modules, or cargo modules.

Das Video stellt die Mehrzweckerweiterungseinheit für das robotische Elektrofahrzeug EO smart connecting car 2 vor. Mit dem Fahrzeug verfolgen die Forscher ein modulares Konzept, welches es ermöglicht unterschiedliche Module miteinander zu koppeln, z.B. Fahrzeug mit Fahrzeug oder Fahrzeug mit Anhänger. Dank der neuen Erweiterungseinheit, die u.a. als Anhänger fungieren kann, konnten die Wissenschaftler die Modularität des EO smart connecting car 2 nun erstmals demonstrieren.
