Advanced Line Following Robot – Step 1: What it takes to build a fast line follower?
In this page I will be telling you what it takes to build a fast line follower. I will be talking about the design, steering mechanisms, sensors, algorithms, etc, which can be implemented. Robot Design The design of the robot plays an important role in deciding its speed and efficiency. The first thing you will want to decide in the design of your robot is the steering mechanism. The various steering mechanisms available are two wheel differential drive, four wheel differential drive, car-type steering mechanism, etc. From my experience, I can tell that two wheel differential drive is the best – it is easier to build, control and is cheap (requires only two motors). Irrespective of the steering mechanism you use, the most important thing to keep in mind is to place the line sensors as far as possible from the steering wheel. This will give the robot, more time to react. Keeping the distance between the sensors and the steering wheel big, will largely reduce the number of over-shootings
