Race of Scribblers

This challenge consists in a race between two Scribblers. The main objective of the game is to have the best lap time and come first to the finish line.  Each Scribbler track completely separated from the other Scribbler by a wall, at one point the track has a crossover. The Scribblers can navigate through the track using the black line on the track or by using the walls as indicators of the left turn.

Race of Scribblers is part of a Scribbler Robot Contest held by SmartCubo Torneo Nacional de Robotica. Visit www.SmartCubo.com for details.
