Line Following Summary and Course Problems

My robot was able to go through most of the course easily, except for the sharp turns and curves. I think it had problems at these sharp turns because it would sense the black line with both front cliff sensors at the same time. Although I had a part of my code to fix this mistake, I still don’t know much about programming, so I just made it turn left when it came across this. The robot could only get across the sharp turn if I started it from a certain side. The sharp curve on the other hand was an obstacle that my robot couldn’t overcome. I think this was so because the two front sensors on the robot are too far apart and the curve is made so that the lines before and after it are really close together. This curve could probably be passed if we could add more sensors to the Create, with the sensors close enough together so that both lines at the curve aren’t sensed at the same time.

Lessons I learned:

C programming allows you to do a lot more than real term.
Having the Create with you, when doing the programming helps a lot.
You have to be precise when programming or your program won’t work at all.
It’s much easier to do the programming when following the steps given to us (I learned this the hard way).
It’s better to ask for help, rather than trying to solve the program yourself when you have no idea what you’re doing.
