?? How It Works: The Science Behind Gas-Powered Robots

1. The 3D Printing Breakthrough

• Printed in a single run using specialized flexible polymer
• Internal pneumatic channels act like artificial muscles
• No wiring or circuits – Movement controlled by gas flow

?? Why It’s Revolutionary: ? No delicate electronics = More durable in harsh environments ? Rapid prototyping – New designs in hours, not weeks

2. Compressed Gas as the "Fuel"

• A small CO? cartridge (like soda machines) powers movement
• Gas flows through channels, causing controlled inflation/deflation
• Sequential activation creates walking motion

?? Efficiency: One cartridge allows ~1,000 steps before recharge.

3. AI-Assisted Design Optimization

• Machine learning helps simulate optimal airflow patterns
• Generates lightweight, efficient structures automatically
• Future potential: Self-improving robot designs via generative AI

?? Case Study: An AI-designed model walked 30% faster than human-engineered versions.
