Most people hate flies, but under certain circumstances they might actually be useful. Engineers from the University of California, in America, are on course to build a minature robot 'fly' the size of a coin, by 2003 which they hope to use for spying or search and rescue missions. So far they have built a tiny bionic wing that can flap 150 times a second.
