Introduction
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.
Aim
Geometrical shapes, diameter of the circle, basic programming.
Center of gravity, steering.
Robot
Almost any robot will do. We use Asimov 2/ Verne robot with a pen attached to the front part of the robot.
Sensors
No sensors is used, except the servo motor.
Example Video
Theory
Usually it is easier to code if the speed is lower. Use only speed 10 or 15. The Asimov/ Verne 2 robot turns exactly (about) 90 degrees when XXXXX
Example Code
Exercises
- Draw a square.
- Draw a house.
- Draw a giraffe.
- Note that the pen draws a wrong line when the robot rotates. How fix to that?
- Try to implement gyroscope to better stay in the given direction.
