Autonomous Shuttle BumbleB: Bertrandt tests a new public transport solution on Mainau Island

The engineering service provider Bertrandt has, within the framework of the 3rd Mainau Climate Dialogue on the island of Mainau, presented the autonomous shuttle 'BumbleB'. The aim of the project is to provide the practical evidence that autonomous vehicles in public local transport are not only technically feasible but also economically operable — especially in rural regions.

Mobility transition and shortage of skilled workers in focus

The mobility transition poses significant challenges, especially for rural areas. According to the Association of German Transport Companies, there is currently a shortage of about 20,000 bus drivers in public passenger transport in Germany. Autonomous vehicles could contribute here to close existing gaps in public transport.

Development Approach and Technology Principles

In the development of the shuttle, Bertrandt relies on the MVP principle (Minimum Viable Product) and open-source technologies. The aim is to strengthen digital sovereignty and enable cost-efficient solutions for autonomous operation. Open-source principles are employed in both software and mechanical design.

Collaborations for Real-World Applications

At the center of the project is the joint development of the vehicle, software, infrastructure, and operations. Bertrandt is currently holding discussions with various municipalities to identify real-world deployment scenarios and to develop potential sites for further test projects. This expands the company's role beyond traditional development services and positions itself as a partner for holistic mobility solutions up to "Mobility-System-as-a-Service" approaches.
