Summary
Exploration of Dutch artist Theo Jansen’s ‘Strandbeests’—autonomous kinetic creature sculptures constructed from PVC conduits that walk across Dutch beaches powered exclusively by wind energy, utilizing Jansen’s mathematical 11-rod linkage mechanism.
Key Points
- Jansen’s 11-Bar Linkage: A precise geometric ratio of eleven connecting rods that converts simple rotational crankshaft motion into a natural, flat walking gait.
- Binary Pneumatic Logic: Storing wind energy in plastic bottles and using logical pneumatic valves to actuate autonomous reflex behaviors (e.g. retreating from water).
- Evolutionary Mechanics: Using genetic algorithms in software to simulate and evolve optimal walking linkage proportions before physical fabrication.
