Trata II is a small prototype of a remote controlled robot with snow-surfing capabilities.
Frits Lyneborg said that his project is still currently in its infancy and that we should soon see his prototype in a more complete video.
For now, here are the beginnings of the snowboarder.
The Trata 2 works like a hovercraft with a propeller motor that mobilizes the mini-vehicle, and a servo motor that acts on the motor and the direction of the robot.
