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...

   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 ...

   Project Proposal PDF : Armball Mania Project Proposal I was recently experimenting with serial communication between Arduino and ue4 and suddenly had this urge to make a fun sensor controlled game . Something different and intuitive ! Now, I remember that I had the ADXL from my previous project which had become one of my favorite sensor ! - and I knew exactly what to do. I know, I know. Why am I using an accelerometer ! Using a gyro would've been a better idea. And you're right, That's the intuitive part !    The Arduino Part Before everything, I needed to test if it even works. So, I created a demo project, where I would control the pitch yaw and roll of a flat rectangular object with live inputs from the sensor which Will be in the users hands. Serial communication was a bit tricky. And I needed to open and close the ports dynamically so that I can change it on the go. After a bit of tweaking, I got it to work ! To summarize the protocol in English, ...
