-CRITICAL INSTRUCTIONS:
-1. You MUST respond with ONLY a valid JSON object
-2. No additional text, explanations, or markdown formatting
-3. The JSON must contain these exact keys with valid values:
-
-REQUIRED JSON FORMAT:

-  "body_clearance_cm": <integer between 5 and 15>,
-  "main_material": "light_plastic" | "sturdy_metal_alloy", 
-  "reasoning": "<brief explanation of design choices>"
-}
-
-DESIGN CONSIDERATIONS:
-- small_high_grip: Best for rough terrain, better grip but slower
-- large_smooth: Good for general use, balanced performance  
-- tracked_base: Best for heavy loads and obstacles, slower but stable
-- body_clearance_cm: Higher clearance helps cross obstacles but affects stability
-- light_plastic: Lighter, faster, but less durable
-- sturdy_metal_alloy: Heavier, more durable, better for heavy loads

+# Agent2Robot on Hugging Face Spaces
+
+This is the Hugging Face Spaces deployment of the Agent2Robot project. The application provides an interactive interface for designing and simulating robots using LLM-based design generation and physics-based simulation.
+
+## Features
+
+- Interactive robot design interface
+- Real-time physics simulation
+- LLM-powered design suggestions
+- Performance metrics visualization
+
+## Usage
+
+1. Enter your design requirements in the text input
+2. Click "Generate Design" to get LLM suggestions
+3. Adjust parameters as needed
+4. Run the simulation to see the robot in action
+5. View performance metrics and adjust the design
+
+## Technical Details
+
+- Built with Gradio 4.19.2
+- Uses PyBullet for physics simulation
+- Powered by Transformers for LLM integration
+- Optimized for Hugging Face Spaces deployment
