=================================================================== WIRED HANDS - A Brief Look at Robotics NEWSCIENCE ------------------------------------------------------------------- Two years ago, the Chrysler corporation completely gutted its Windsor, Ontario, car assembly plant and within six weeks had installed an entirely new factory inside the building. It was a marvel of engineering. When it came time to go to work, a whole new work force marched onto the assembly line. There on opening day was a crew of 150 industrial robots. Industrial robots don't look anything like the androids from sci-fi books and movies. They don't act like the evil Daleks or a fusspot C-3P0. If anything, the industrial robots toiling on the Chrysler line resemble elegant swans or baby brontosauruses with their fat, squat bodies, long arched necks and small heads. An industrial robot is essentially a long manipulator arm that holds tools such as welding guns or motorized screwdrivers or grip pers for picking up objects. The robots working at Chrysler and in numerous other modern factories are extremely adept at performing highly specialized tasks - one robot may spray paint car parts while another does spots welds while another pours radioactive chemicals. Robots are ideal workers: they never get bored and they work around the clock. What's even more important, they're flexible. By altering its programming you can instruct a robot to take on different tasks. This is largely what sets robots apart from other machines; try as you might you can't make your washing machine do the dishes. Although some critics complain that robots are stealing much-needed jobs away from people, so far they've been given only the dreariest, dirtiest, most soul-destroying work. The word robot is Slav in origin and is related to the words for work and worker. Robots first appeared in a play, Rossum's Universal Robots, written in 1920 by the Czech playwright, Karel Capek. The play tells of an en gineer who designs man-like machines that have no human weakness and become immensely popular. However, when the robots are used for war they rebel against their human masters. Though industrial robots do dull, dehumanizing work, they are nevertheless a delight to watch as they crane their long necks, swivel their heads and poke about the area where they work. They satisfy "that vague longing to see the human body reflected in a machine, to see a living function translated into mechanical parts", as one writer has said. Just as much fun are the numerous "personal" robots now on the market, the most popular of which is HERO, manufactured by Heathkit. Looking like a plastic step-stool on wheels, HERO can lift objects with its one clawed arm and utter computer-synthesized speech. There's Hubot, too, which comes with a television screen face, flashing lights and a computer keyboard that pulls out from its stomach. Hubot moves at a pace of 30 cm per second and can function as a burglar a larm and a wake up service. Several years ago, the swank department store Neiman-Marcus sold a robot pet, named Wires. When you boil all the feathers out of the hype, HERO, Hubot, Wires et. al. are really just super toys. You may dream of living like a slothful sultan surrounded by a coterie of metal maids, but any further automation in your home will instead include things like lights that switch on automatically when the natural light dims or carpets with permanent suction systems built into them. One of the earliest attempts at a robot design was a machine, nicknamed Shakey by its inventor because it was so wobbly on its feet. Today, poor Shakey is a rusting pile of metal sitting in the corner of a California laboratory. Robot engineers have since realized that the greater challenge is not in putting together the nuts and bolts, but rather in devising the lists of instructions - the "software - that tell robots what to do". Software has indeed become increasingly sophisticated year by year. The Canadian weather service now employs a program called METEO which translates weather reports from English to French. There are computer programs that diagnose medical ailments and locate valuable ore deposits. Still other computer programs play and win at chess, checkers and go. As a results, robots are undoubtedly getting "smarter".

Struthiomimus - Facts and Figures

Struthiomimus - Facts and Figures Name: Struthiomimus (Greek for ostrich mimic); pronounced STROO-thee-oh-MIME-us Habitat: Plains of western North America Historical Period: Late Cretaceous (75 million years ago) Size and Weight: About 10 feet long and 300 pounds Diet: Plants and meat Distinguishing Characteristics: Ostrich-like posture; long tail and hind legs About Struthiomimus A close relative of Ornithomimus, which it closely resembled, Struthiomimus (ostrich mimic) galloped across the plains of western North America during the late Cretaceous period. This ornithomimid (bird mimic) dinosaur was distinguished from its more famous cousin by its slightly longer arms and stronger fingers, but because of the position of its thumbs it couldnt grasp food quite as easily. Like other ornithomimids, Struthiomimus likely pursued an opportunistic diet, feeding on plants, small animals, insects, fish or even carrion (when a kill was left unattended by other, larger theropods). This dinosaur may have been capable of short sprints of 50 miles per hour, but had a less taxing cruising speed in the 30 to 40 mph range.
