			Drawing on a large paper using a robot is funny and involving. Use a large paper and try to stay on the paper. Logo programming is oldie but goodie.

			Geometrical shapes, diameter of the circle, basic programming.

			Center of gravity, steering.

	== Robot ==		== Robot ==

			Almost any robot will do. We use Asimov 2/ Verne robot with a pen attached to the front part of the robot.
