Overview

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

Bioinspired Hardware

  • studies processes and

mechanisms in nature

  • seeks alternative

hardware design and implementation

Bioinspired Hardware: Results

  • biomorphic robots

– mostly insectlike

  • computer vision

– navigation – shape recognition

  • more efficient design for mechanisms

– seed pod fliers – adhesive surfaces: beyond velcro

NASAs Biomorphic Explorers

  • mobile platforms useful for exploration
  • Bioinspired Engineering of Exploration

Systems (BEES)

  • idea: many small biomorphic explorer

machines

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

Dragonflies See the Horizon

  • additional eyes (ocelli) see a short spectrum
  • UV and green input combined together
  • result: correct attitude detected

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

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

The Robot Hexapod RHex

  • cockroach-inspired
  • so far, unsurpassed robotic

maneuverability

  • speed up to 3 meters
  • a possible candidate for Mars 2007

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

Future?

  • bio-inspired materials continue to pop up
  • swarms of fast-maneuvered robots in

helpful tasks
