I assembled and uploaded the sketch for this P-bot which Fr Demet and I bought from
E-Gizmo (near DLSU). It took me a day to do this since all the parts are present... just a few soldering and a lot of uploading programs.
You see, this little thing is a 3-in-1 Robot. It can work as a Line
tracer, a Sumo, and an Obstacle Avoidance just using the basic sketches.
Heck if you go advanced programming you can even join it in the
micromouse race since you could program it to solve mazes. I haven't got
that last one right yet.
