Robot Programming
I need help to do this. This is the task that my teacher gave but i really cant do it. Tried with node.js, arduino and much more. Try to read it too but still hard. I hope someone can solve this and teach me how to do it because i also need to explain and present it to my teacher how i got the solution.
Here are the question and the code:
The question is:
1. Draw and explain the path of the line follower robot at Diagram 1 according to the programming in Diagram 2.
2. Explain each section of the programming in Diagram 2 according to your understanding.
the diagram 2 is:
here the document of the assignment
