The Dining Philosophers

**AURA (Phone Saathi)** is a hybrid, autonomous Android agent that navigates your phone for you. You speak naturally to it using the **Gemini Live API**, and it executes complex app workflows step-by-step. **Why we chose this problem:** In regions like India, millions face a steep digital literacy curve and struggle with complex app interfaces, yet internet connectivity remains spotty and privacy around tasks like payments is critical. We built AURA to solve this dual challenge by targeting two tracks: 1. **Real-Time Multimodal Interaction:** We use Gemini Live to break the rigid, turn-based chatbot model, giving users a fluid, interruptible voice assistant that truly understands intent. 2. **Local-First Agents on Gemma 4:** We brought the "sense-decide-act-check" loop directly to the edge. When privacy or connectivity demands it, AURA falls back to a local Gemma 4 model (via LiteRT-LM) to execute tasks entirely offline, halting automatically before sensitive payment boundaries.
