Imagine you are walking with a friend and suddenly you see someone coming towards you. You and your friend would move to the side so that you don't bump into the person. This is what collision avoidance is. It's the process of avoiding something that's coming towards you to prevent a collision.
Now, think about a car. When a driver is on the road, they need to look out for other cars, pedestrians, and obstacles to avoid a collision. They use their eyes, ears, and sometimes technology like sensors and cameras to detect when something is getting too close. The car's computer system then sends signals to the car's brakes and steering to avoid the collision.
Collision avoidance is important because it keeps people safe. It's like playing a game of dodgeball - you want to avoid getting hit by the ball. In the same way, collision avoidance helps us avoid accidents that could cause injury or even death. It's an important part of driving, flying airplanes, and operating any machine that moves, such as a forklift in a warehouse.
