This Lego Technic RC vehicle is modeled on the Roomba vacuum cleaner from iRobot. The Roomba can drive forwards, backwards and rotate on the spot. This RC lego technic model attempts to do the same but with four wheels instead of two, similar to a supermarket trolley. The vehicle can switch between driving mode where it can drive forwards or backwards using your remote control, or it can switch to rotation mode.

The rotation mode is remotely activated by a lego technic power functions servo motor and it rotates each of the four wheels by 45 degrees to make a circular configuration. This allows the model to rotate on the spot in either a clockwise or anti-clockwise direction.
