Cyber-Physical Mobility Lab An Open-Source Platform for Networked and Autonomous Vehicles

We introduce our Cyber-Physical Mobility Lab (CPM Lab), a development environment for networked and autonomous vehicles. It consists of 20 model-scale vehicles for experiments and a simulation environment. We show our four-layered architecture that enables the seamless use of the same software in simulations and in experiments without any adaptions. A Data Distribution Service (DDS) based middleware allows to adapt the number of vehicles during experiments in a seamless manner. Experiments with the 20 vehicles can be extended by unlimited additional simulated vehicles. Another layer is responsible for synchronizing all entities following a logical execution time approach. We pursue an open policy in the CPM Lab and will publish the entire code as well as construction plans online. Additionally, we will offer a remote-access to the CPM Lab using a web interface. The remote-access will be publicly available. The CPM Lab allows researchers as well as students from different disciplines to see their ideas develop into reality.

Networked and Autonomous Model-scale Vehicles for Experiments in Research and Education

This paper presents the $\mathrm{\mu}$Car, a 1:18 model-scale vehicle with Ackermann steering geometry developed for experiments in networked and autonomous driving in research and education. The vehicle is open source, moderately costed and highly flexible, which allows for many applications. It is equipped with an inertial measurement unit and an odometer and obtains its pose via WLAN from an indoor positioning system. The two supported operating modes for controlling the vehicle are (1) computing control inputs on external hardware, transmitting them via WLAN and applying received inputs to the actuators and (2) transmitting a reference trajectory via WLAN, which is then followed by a controller running on the onboard Raspberry Pi Zero W. The design allows identical vehicles to be used at the same time in order to conduct experiments with a large amount of networked agents.
