18. CodyPlotter and CodyPrinter

What is the difference between a plotter and a printer? Find out by playing this unplugged coding activity.

Required material: in addition to the CodyRoby kit, I used a green marker and a new modelling clay robot, but this is optional.


Can you explain the difference between a plotter and a printer?

What design would RobyPrinter produce by moving along the lines on the board, if it executed the sequence of commands dictated at the end of the video?
