Testing the robot in school.

This is my first build.  It is basically the stock one, as described in the included instruction manual, but with the following important modifications.

1) Removed the touch sensor on the back

2) Removed the arm attachment on the front

3) Added the lamp (with a coloured brick) on the front

Removing the touch sensor and the arm attachment make the robot much more durable in the classroom.  Adding the lamp allows for more instant visual feedback to the students.
