To bring the world closer to the live action at the Alpine Ski Championships, we programmed a battalion of autonomous robots to craft fan messages in the snow. The result was an alpine artwork masterpiece – the size of 16 soccer fields.

Our team modified Honda Snow Blowers to follow a GPS path autonomously, at an accuracy of up to two centimetres. To keep on track, the robots used high precision GNSS modules that communicated the information received from the satellites to a base station, and verified it with the digital layout of each message.

We programmed the robots using algorithms made for self-driving cars – with some special additions. For the really tight turns the robot’s auger pivots automatically, reducing the surface area in the snow and maintaining a precise drawing. To program a seamless, uninterrupted route for the robots, our designers created a bespoke font and compiled fan messages into one carefully-crafted layout in 3D studio max.
