I've posted before about the Scribbler Robot Camps that I am doing with the Monroe City School system. After the students learn the basic functions of the Scribbler (demo, sound, LEDs, motor control, etc.), we have a contest. They are to make their Scibbler play "Charge!", draw one of their initials, and then play "tada!" They have to stay on a piece of 22" X 28" poster board.
They have to work on making the Scribbler run straight, the time duration of the strokes in the letter, turning the proper angles, etc. They get to work on this for about 20 minutes one day and then get about 20 minutes the next day. The work is done based on what they have learned at that point and trial and error for lengths and turn angles and other issues.
This video is of one of the student's work at Carroll High School. Her "K" was the most complex letter chosen. We had Ts, Ls, Ds for instance, but this capital K is impressive. Multi-stroke letters (where they have to back-track) are the hardest. This one was a winner!
By this time the contest is held - the students have had less than 5 hours experience with their Scribblers and robotics!
