Acknowledgment

This project, EDITH - The Follow Me Robot, was developed as a part of a learning experience during the final year of engineering. The idea and guidance for this project were sourced from a tutorial created by the YouTube channel DIY Builder(tutorial link - https://www.youtube.com/watch?v=yAV5aZ0unag&t=5s) and their Instagram account @diy.builder(https://www.instagram.com/diy.builder/).

We would like to express our gratitude to DIY Builder for providing valuable insights, instructions, and inspiration for this project. Without their contribution, this project wouldn't have been possible.

I would like to extend my heartfelt gratitude to the Integral University Robotics Lab (https://www.robotics.iul.ac.in/) for their invaluable support throughout the development of this project. Their generous provision of funds, tools, and a conducive environment for research and innovation has been instrumental in bringing this project to fruition. I am also deeply appreciative of their guidance and expertise, which have played a pivotal role in the successful design and implementation of the follow me robot. This project would not have been possible without their unwavering support and mentorship.
