Eight If by Land, None If by Sea

摘要

People who build robots envy the performance of animals- the flawless landing of a bird on a branch, the agility of a mountain goat stepping lightly along a cliff ledge. Some engineers are particularly interested in building robots that can walk both underwater and on dry land. The robot they envision will be able to jump out of a marine transport ship, for example, and defuse mines hidden in the surf. The crab is the creature these engineers hold dear.
