Key Achievements ✅ Seamless Real-World Navigation: The robot now autonomously navigates dynamic spaces, avoiding obstacles and reaching destinations with precision—powered by ROS 2 Nav2 and our tuned path-planning algorithms. ✅ End-to-End AI Integration: Combining ChatGPT-4o, RAG, and Whisper, the robot answers contextual queries (e.g., “Where’s the lobby?”) and executes navigation tasks in one fluid workflow. Demo Highlights 1️⃣ Natural Language Interaction: Asked the robot for department info, and it responded instantly with accurate, AI-retrieved details. 2️⃣ Voice-Guided Navigation: Commanded, “Take me to Teleconference Room ”—the robot mapped the optimal path, dodged obstacles, and arrived autonomously. 3️⃣ Intuitive UI Feedback: The onboard interface displayed interactive prompts for users.
