  1. BIOINSPIRED HARDWARE Erki Suurjaak

  2. Overview • bioinspired hardware • NASA’s exploration systems • robots Ariel and RHex • future?

  3. studies processes and mechanisms in nature seeks alternative hardware design and implementation Bioinspired Hardware

  4. Bioinspired Hardware: Results • biomorphic robots • mostly insectlike • computer vision • navigation • shape recognition • more efficient design for mechanisms • seed pod fliers • adhesive surfaces: beyond velcro

  5. NASAs Biomorphic Explorers • mobile platforms useful for exploration • Bioinspired Engineering of Exploration Systems (BEES) • idea: many small biomorphic explorer machines

  6. Bee-Inspired Vision & Guidance • amazing results with a handful of neurons • simple and effective hazard avoidance • compound eyes give panoramic vision • simple landing with minimal computation

  7. Dragonflies See the Horizon • additional eyes (ocelli) see a short spectrum • UV and green input combined together • result: correct attitude detected

  8. BEES: Seed Wing Pod Fliers • plant inspired payload distribution • 20 cm wingspan • load around 60 grams • simpler and smaller than parachutes • slower descent than parachutes • 2x smaller shock on impact than parachutes

  9. Other Bio-Inspired Robots: Ariel • movement inspired by crabs • capable of negotiating terrain unaccessible for wheeled machines • capable of underwater movement and resisting wave impact

  10. The Robot Hexapod RHex • cockroach-inspired • so far, unsurpassed robotic maneuverability • speed up to 3 meters • a possible candidate for Mars 2007

  11. Geckos: Beyond Velcro • geckos walk on walls and ceilings • a leg can support the entire body • use weak intermolecular attraction • 1,000,000 setae lift ~20 kg

  12. Future? • bio-inspired materials continue to pop up • swarms of fast-maneuvered robots in helpful tasks
