Video tutorials, Courses, Materials and Programs

Showing the same run, but from a different angle. This allows you to see more of the way we sensors work and how exactly the robot positions itself.

We would look at the rules of the competition over our small model and we would start solving the field.

We would continue from the previous program where we used variables and we would change this to arrays.

We list the number of decisions that the robot is making while following the line. Then, we group them and decide on the number of sensors to be used.

Next important state is Turn Right with our robot. This happens when we detect a line on the right. 

We can Turn Right. We can Turn Left. How do we decide which way to go if there are lines both to the left and to the right. Check out the video.

All worked as expected, up until know because the robot got lost. This happens when we turn right and the line does not continue to the right. Now the robot must somehow understand that it is "lost" and escape.
