Team Description
We are a Czech Formula Student team that has been competing since 2010. We had designed, manufactured, tested, and raced with 15 Dragons at 33 races and got 68 podiums. In this year, we are planning to project all the experience from 10 years of building combustion and 4 years of building electric vehicles to create our most powerful car: Dragon e5! This electric beast would also be carried by a huge innovation, which is an all-wheel-drive concept!

Since 2010, the TU Brno Racing team has successfully designed and built 13 Formula Student cars, 10 were powered by combustion engines. We are thrilled to present our latest achievement: the Dragon e4, fourth electric formula car! The construction of this remarkable vehicle was carried out by 50 talented students from 4 faculties of Brno University of Technology. With the Dragon e4, we have set our sights high, aiming to achieve the best results in the history of our team.

| Highlights of the DV system | Our autonomous system is built on the Robot operating system platform. Cones are detected using lidar and stereoscopic cameras. Cone positions from cameras are calculated using a depth map built from the camera image. We use SLAM algorithm for the localization of our vehicle on the map. Motors and steering are controlled using PID regulators. |
