The Ultra-Efficient MA Chassis

The MA (Midship AERO) Chassis has its motor in the center, and features a design which focuses upon achieving outstanding aerodynamic performance. It has six individual low-friction rollers, a rear skid bar and other speedy features developed thanks to years of design experience. The single-piece monocoque frame also guarantees that assembling and keeping the car well-maintained is a task that can be performed by beginners and veteran racers alike.

What is the Roborace DevBot 2.0?

Roborace is a revolutionary series for AI-controlled cars. DevBot 2.0 is the all-electric vehicle used for Roborace Seasons Alpha and Beta, a rear-wheel drive car that can be piloted by a human or AI driver, with lidar, cameras and GPS helping the car to navigate when in autonomous mode. The Emotion System on the side of the car shows various different icons to signify the DevBot 2.0's status and actions.
