Play chrome's dino game physically 🦕.

Sat, 10 Jul 2021 15:47:57 +0000

TL;DR: In this project, we are going to play the chrome dino game physically with the help of machine learning and embedded electronics.

Introduction

Due to the 2nd wave of a global pandemic, I was kept inside my house without doing much physical activity, Last month I got an Intestinal gas related issue and consulted a doctor, and he mentioned doing small physical activities will help avoid these kinds of problems, I tried to use a mobile application that helped to do physical activities without equipment, I also invited my little nephews to do exercise with me, but they are not interested. Then I thought of doing something fun and burn the calory, that’s how the project born.
