short_description: Cosmos Reason 2 healthcare Physical AI — 3D arena

🛡️ AEGIS-Reason: Post-Training Cosmos Reason 2 for Vision-Grounded Multi-Robot Healthcare Coordination

NVIDIA Cosmos Cookoff 2026 — Competition Submission

The first-ever application of Cosmos Reason 2 to healthcare Physical AI — a fully interactive, physics-grounded 3D hospital arena with live VLM inference, uncertainty-quantified multi-robot coordination, and a 119-entry medical knowledge base across 4 embodied robot classes and 12 clinical domains.

🏗️ Isaac Lab 3D Arena — Main Showcase

The centerpiece is a 449,580-character self-contained 3D simulation (zero external dependencies) orchestrating 4 classes of healthcare robots inside a unified hospital floor plan:

Robot	Physics Model	Key Metric (seed=42)
🦾 Surgical Arms (da Vinci Xi)	7-DOF kinematics, Jacobian IK, Kelvin-Voigt tissue	1.9× speed, 90% tremor reduction
🏥 Hospital AMR Fleet	DWA, SLAM + A*, collision avoidance	1.3× throughput, collisions 2 → 0
🚁 Medical Drones	3D Bézier flight, wind-coupled dynamics	73% on-time, energy −16%
🦿 Rehab Exoskeleton	Inverted-pendulum gait, biomechanical torque	Falls 28 → 9, 6MWT 152 → 208 m

Every slider change re-simulates all 4 robot subsystems and updates entity counts, physics trajectories, narration text, and CR2 inference chains in real time.

⚡ Cosmos Reason 2 Integration

CR2 (8B, Qwen3-VL, 256K context) serves as the decision-making backbone in three integration patterns: live VLM inference with 5-axis reasoning chains, LoRA post-training (r=16, α=32, 22 hospital SFT examples), and critic/reward role in the Cosmos closed-loop flywheel.

📊 Architecture

10,989 lines of research-grade Python across 7 modules (A–G), producing 112 functions, 24 interactive Gradio tabs, 14 interactive 3D plots, and 22 event-driven callbacks. The full NVIDIA Physical AI stack: Cosmos WFMs, Isaac Sim 6.0, PhysX 5.6.1, Dynamo, NIM v1.6.0, Jetson AGX Thor (2,070 FP4 TFLOPS), Earth-2, and CRAG retrieval.

🚀 Running Locally

git clone https://huggingface.co/spaces/YOUR_USERNAME/AEGIS-Reason
cd AEGIS-Reason
pip install -r requirements.txt
python app.py

Optional (for live CR2 inference — requires GPU with ≥8 GB VRAM):

pip install torch transformers accelerate peft

Without a GPU, the application runs in cached/simulated mode with full interactivity across all 24 tabs.
