Theo Jansen’s 3D printed Strandbeest continues to evolve with an even more elaborate walking mechanism and a centipede-like walking motion. The latest evolution called ‘Animaris Geneticus Ondularis‘ walks on twenty separate legs that move in a wave sequence. This new configuration results in a fluent walking motion, different from its twelve legged predecessors. It incorporates 122 moving parts, showcasing the complexity of mechanisms possible with 3D printed fabrication. It is also slightly larger than its predecessors. The operating principle of ‘Animaris Geneticus Ondularis’ is based on one of Theo Jansen’s original beach walkers, the ‘Animaris Ondula’.
