Science Fiction's Robotics Laws Need Reality Check

Artificial intelligence researchers often idealize Isaac Asimov's Three Laws of Robotics as the signpost for robot-human interaction. But some robotics experts say that the concept could use a practical makeover to recognize the current limitations of robots.

Self-aware robots that inhabit Asimov's stories and others such as "2001: A Space Odyssey" and "Battlestar Galactica" remain in the distant future. Today's robots still lack any sort of real autonomy to make their own decisions or adapt intelligently to new environments.

But danger can arise when humans push robots beyond their current limits of decision-making, experts warn. That can lead to mistakes and even tragedies involving robots on factory floors and in military operations, when humans forget that all legal and ethical responsibility still rests on the shoulders of homo sapiens.

"The fascination with robots has led some people to try retreating from responsibility for difficult decisions, with potentially bad consequences," said David Woods, a systems engineer at Ohio State University.

Woods and a fellow researcher proposed revising the Three Laws to emphasize human responsibility over robots. They also suggested that Earth-bound robot handlers could take a hint from NASA when it comes to robot-human interaction.

Siemens Fills Russia’s Need for High-Speed Train

The Soviet Union, despite its dependence on railroads, had fallen far behind Japan and Western Europe on high-speed transport. That the order came to the Rubin design bureau suggests that Moscow viewed catching up as a matter of national security.

The result of the little-known program was a slate-gray, round-nosed locomotive called the Sokol, Russian for falcon, that petered out soon after the Soviet Union did. The prototype achieved a top speed of only 143 miles an hour — hardly breaking a sweat by high-speed standards.

The fall of the Falcon created an opening for Siemens.

This December, high-speed trains designed by the German conglomerate and adapted for Russian winters will ply the rails between St. Petersburg and Moscow. But Siemens hopes their final destination will be the last laggard of the high-speed age: the United States.

For years, businesspeople and politicians have dreamed about America entering the high-speed era, but Amtrak has been plagued by budget and service problems and the closest Americans have come to high speed is the Acela, which rarely runs at what Europeans call high speed.

Now Siemens and its competitors are hoping all that has changed. The economic stimulus passed by Congress in April includes a five-year, $13 billion high-speed rail program. Siemens is one of four makers of high-speed trains, none of them based in the United States, that hopes to take advantage of it.

Siemens executives said the tilt toward political acceptance of high-speed rail in the United States presented a remarkable business opportunity — assuming the systems get built.

The United States “is a developing country in terms of rail,” Ansgar Brockmeyer, head of public transit business for Siemens, said in an interview aboard the Russian test train, as wooden country homes and birch forests flickered by outside the window. “We are seeing it as a huge opportunity.”
