Previously, when we showcased our initial project at the national science fair, we presented "Armball Mania," a novel and intuitive sensor-controlled game. This project utilized an accelerometer connected to a compact Arduino Nano, with serial communication enabling the transfer of orientation data to an Unreal Engine game. The game's objective was to balance a ball on a football field and score goals by manipulating the field's orientation with the accelerometer mounted on a DIY glove worn by the user. The project was a hit at the fair in Kolkata, drawing long lines of enthusiastic students and children eager to experience the game. Despite the success, we encountered significant challenges with the accelerometer. The sensor's sensitivity to minute hand movements caused jittery and unstable outputs, making the gameplay less smooth and precise than desired. To overcome this, we decided to upgrade to a gyroscope. The gyroscope provided a remarkable improvement in a...

  Today I'm going to show you how I turned a broken pocket mist generator into: A Contactless Mist Sanitizer Machine  in just one day. Sounds cool, right? Let's get started ! First, let me explain what a pocket mist generator is. It's basically a device that sprays a fine mist of liquid, usually water or sanitizer, to moisturize or disinfect your skin or surroundings. It's handy and portable, but mine stopped working after a few months of use. So I decided to open it up and see what's inside. To my surprise, I found out that it doesn't use any heating element or pump to create the mist. Instead, it has a tiny diaphragm that vibrates at a very high frequency, around 100 kHz, and breaks the liquid into tiny droplets that form the mist. This is called ultrasonic atomization, and it's very efficient and quiet. I wanted to control this diaphragm using my Arduino Uno, but I couldn't generate such a high frequency with it. So I had to use the origi...

       We have named it 'Cookie Bot' 🍪 Cookie Bot is a multipurpose mini desktop assistant robot that you can control with your voice when needed but also has a mind of its own ! It uses a combination of AI, Machine Learning, and speech recognition to control its movements and actions based on different situations and surroundings. Users can interact with the robot through voice commands and its voice assistant artificial intelligence system allows it to detect and understand user commands in different natural languages including English and Hindi !  Cookie Bot acts lively, moves around on its own using a path finding algorithm to navigate and avoid obstacles while responding to different commands from the user. The Cookie Bot uses a LIDER sensor to detect objects in its path and a Ultrasonic sensor to sense objects and objects in its surrounding environment. Here's a video of the first working prototype : Prototype 1 : December 15th, 2022 Prototype 1 : Projec...

   The Project Proposal Objectives : The future calls for a safer, more efficient, and reliable habitable environment for everyone throughout the globe - an attack, accident, and disaster-proof infrastructure with zero casualties in such events. But if there are any, we need to have the technology and resources to combat such situations. SARDA is a deployable robotic unit intended to help first responders in such crucial situations to carry out search and rescue operations in dangerous environments.  When deployed into the disaster site, it helps to map and render a dynamic color coded 3D model of it's immediate surrounding along with data like temperature and humidity ; Which, not only aids the rescue team to better navigate the terrain but also informs us in case of fire and smoke along with it's exact location. This digital twin can also be overridden with manual control, providing us with an efficient two-way communication system. The Deploy-able unit ...
