If you believe in teaching from the ground up, this is something you will want to check out. Most engineering educational content starts at highest level, using graphical blocks and buttons to press, but we're going to try to use the 3DoT board to teach how things really work, instead of how to press buttons.

The workshop is two parts, each probably an hour long. By the end of the first workshop the students can make the robot's motors and lights turn on and off, and at the end of the second workshop it can follow a line drawn with black marker. All programmed in machine code.
