Why Do Robots Need Pure Pursuit?
Imagine you have a robot car, and you want it to follow a winding road/curved path. If the robot just tries to go straight or only follows the exact points on the path, it might turn too sharply, wobble, or even go off track!
How Does Pure Pursuit Help?
Instead of following the path like a dot-to-dot drawing, the robot looks a little ahead and aims for a point in front of it. This way, it turns smoothly and follows the path naturally, just like how you ride a bike or drive a car. This can be compared to a donkey chasing a carrot(as the donkey will keep moving forward to reach the carrot, but never actually reach it and eat it, till the path ends).
