Observing problems and trying to find a solution for it is one step towards creating a genius.

Ever thought of how safer it would be by knowing if there is another vehicle coming from the other side of a blind corner? Let’s explore a common problem which we face while driving in hilly areas.

Accidents at Hairpin curves in hilly areas

Almost at any hill-stations you would have seen blind zones or hairpin zones. The road takes a very sharp turn and due to the hill in-between, it’s impossible for the vehicle driver to see what’s coming from the side. That causes fatal accidents in many cases and causes lives.

While Mitthu was travelling with his family, he observed these blind zones and hilly areas and made up his mind to find a solution to this problem.

Accident prevention system in hilly area blind zones

Mitthu discussed the problem with Misari.

What if we make a sound and light as a warning for the driver that something is coming from the other side? Misari suggested.

Wow! But, how? Mitthu was excited and perplexed at the same time.

Using an IR Sensor! Misari revealed the game plan.

WOW – yes we can. Misari and Mitthu started working to make a working model of Accident prevention system in hilly areas’ blind corners.

So put your creative hats on and see how we can make use of our Havi Elements to create a solution for this. Everything you need to make this project can be found in 2 boxes of Havi Elements – DIY Robotics Starter Kit, OR 2 boxes of Havi Elements – DIY Object sensor projects kit (without LED though) You can have one of each as well. Or you can contact us to order the customized pack for making this project.

The making

This project is created in two sections:

1. First we create the circuit using Havi Elements.
2. Second, we create a blind turn scenario using our crafting skills.

Section 1: Creating the circuit.

IR (Infrared) sensors are used to detect the presence of the object. Checkout How IR works for more details.

Coupling IR sensor with Buzzer and LED will make the buzzer emit sound and LED glow whenever an object is detected by the IR Sensor.

Snap the elements to prepare the circuit as shown here.

Now your circuit is ready and you can check by keeping an object closer to the IR sensor if the buzzer and LED works well. You can adjust the sensitivity of the IR sensor using the controller provided in the element.

Section 2: Creating a blind corner scenario.

A hairpin bend or blind corner in the hilly area is a turn on the road where the view of what is behind the corner is obstructed mostly by a hill. Sometimes even a building, or tree can also cause a blind spot. Warning signs are often placed on such roads to warn traffic.

You can watch the videos and photos provided in this blog and also search for other images of blind corners over the internet and create a craft model to demonstrate the working.

IMPORTANT: Note the placement of the IR Sensors and the associated buzzers and led lights in your model.

Once you have created the scenario, get two toy cars and demonstrate the working.

How it works?

The IR sensors are placed on the left lane of each side of the curve.

As the car approaches the curve, it is detected by the sensors placed there and a notification LED glows on the other side of the curve with a buzzer sound to alert the traffic coming from that side about the approaching car.

This works on both the sides of the curve.

This notifies the driver about the vehicles approaching from the other side of the blind corner. The driver then can carefully take the turn and ensure a pleasant and safe journey.

Advantages when implemented in the real world

Accidents can be prevented and a lot of lives and loss of vehicles can be saved when implemented at hairpin curves in the real world.

You can get the components from two boxes of Robotics Starter Kit Or two boxes of this STEAM kit. Or can contact us to inquire for the kit.

Keep creating.
