CHAI

CHAI (Companion Humanoid AI) is a real-time companion system for the Unitree G1 humanoid robot that detects approaching humans, greets them and autonomously clears obstacles from the path using the robot's arm, acting as a guide for visually impaired users. It uses Nebius AI Studio's VLM (Qwen2.5-VL-72B) for vision and LLM (Llama-3.3-70B) for decision-making, and runs in both MuJoCo simulation.
