Line Follower Robot v2 + Obstacle detector

The robotic course was offered for the first time at my institute and it was a great learning experience for both the students as well as the professor. As always the first project of any robotics course is to build a line follower robot.

LFR is like a 101 project of robotics. I had made a lfr 2 years ago but it was for fun and was very easy. This time, we made a robot using prebuilt components and it was a project worth doing.

We were given a chassis with 4 wheels and 2 motors. We had a microcontroller board with us. We had a line detecting sensor which was built using IR. An obstacle detector sensor was a Sharp distance sensor. So we had all the components ready. But the real task was how to assemble it properly. It took around a week to gel all those things together and come up with a working prototype but the time was worth investing.

I learnt about many important issues like power consumptions and sourcing which are often neglected. How to counteract the slip of the wheels, how to make motors move slowing or faster and lots of other smalls things which are very important for the proper working of the robot.

Bit untidy but it works :)
