It focuses on affordable autonomous navigation using smartphone sensors and real-time communication.<br> Tech stack: Node.js, Express.js, Socket.IO, HTML, CSS, JavaScript, Canvas.<br> We learned a lot about sensor-based navigation, real-time communication, and building a working prototype under hackathon time constraints.<br> Feedback and suggestions are welcome!</p> java fastapi
