IR line follower

Inspiration

In this world of complicated solutions, I felt the need to try to implement some very simple solution to solve some problems that have recently cropped up. COVID-19 has made us alter our lifestyles in major ways. One of them is not going outside, and avoiding contact with surfaces. Here I have developed a very simple bot for our house to accept deliveries and make it safer for both the person delivering and us.

What it does

It is a very simple line following bot that uses 3 IR sensors, a guided path of white strip against black and follows the path. It can be manually overriden using a PS controller. It when turned on simply follows the line and depending on a couple of more attachments can perform simple activities like picking up or dropping objects.

How I built it

I built it using arduino, it's IDE and 3 IR sensors. I have tried a couple of other attachments like servo motors, though due to the lack of the right materials, I haven't been able to demo correctly.

Challenges I ran into

In this lockdown it is hard to get hands on the right material in a short time, but I feel I managed fine without the extra componants and found the joy in building something simple.

What's next for IR line follower

I am planning to add some extra componants like motors and UVC lights to add to its utility value. I also plan to replace the arduino with a microcontroller with wireless communications
