The idea of humanoid robots is not new. They have
been part of the imaginative landscape ever since Karl Capek, a Czech writer,
first dreamed them up for his 1921 play "Rossum's Universal Robots", (The word
"robot" comes from the Czech word for drudgery, robota.) Since then, Hollywood
has produced countless variations on the theme, from the sultry False Maria in
Fritz Lang's silent masterpiece "Metropolis" to the withering C-3PO in "Star
Wars" and the ruthless assassin of "Terminator". Humanoid robots have walked
into our collective subconscious, coloring our views of the future.
But now Japan's industrial giants are spending billions of yen to make
such robots a reality. Their new humanoids represent impressive feats of
engineering: when Honda introduced Asimo, a four-foot robot that had been in
development for some 15 years, it walked so fluidly that its white, articulated
exterior seemed to conceal a human, Honda continues to make the machine faster,
friendlier and more agile. Last October, when Asimo was inducted into the Robot
Hall of Fame in Pittsburgh, it walked on to the stage and accepted its own
plaque.
At two and a half feet tall, Sony's ORIO is smaller and
more toy-like than Asimo. It walks, understands a small number of voice
commands, and can navigate on its own. If it falls over, it gets up and resumes
where it left off. It can even connect wirelessly to the internet and broadcast
what its camera eyes can see. In 2003, Sony demonstrated an upgraded QRIO that
could run. Honda responded last December with a version of Asimo that runs at
twice the speed.
In 2004, Toyota joined the fray with its own
family of robots, called Partner, one of which is a four-foot humanoid that
plays the trumpet. Its fingers work the instrument's valves, and it has
mechanical lungs and artificial lips. Toyota hopes to offer a commercial version
of the robot by 2010. This month, 50 Partner robots will act as guides at Expo
2005 in Aichi, Japan.
Despite their sudden proliferation,
however, humanoids are still a mechanical minority. Most of the world's robots
are faceless, footless and mute. They are bolted to the floors of factories,
stamping out ear pails or welding pieces of metal, making more machines.
According to the United Nations, business orders for industrial robots jumped
18% in the first half of 2004. They may soon be outnumbered by domestic robots,
such as self-navigating vacuum cleaners, lawn mowers and window washers, which
are selling fast. But neither industrial nor domestic robots are
humanoid.
