{{B}}The Robot
Man{{/B}}
? ?According to Hans Moravec,universal robots will take
over all the physical activities that we engage in,leaving us with little to do.
Moravec sees four generations on the road to true universal robots. The first
generation will be here by 2010 and will consist of free-ranging robots that can
navigate by building an internal mental map of their surroundings. In new
situations they’ll be able to adapt, unlike today’s mobile ?industrial
robots. These robots will have the computing power to cope with simple speech
and text recognition,and will be used for tasks such as domestic
cleaning.
? ?The second generation will arrive around 2020 and will
be distinguished by the ability to learn. Second ?generation robots are
programmed with sets of primitive tasks and with feedback that provide"pleasure"
and "pain"stimuli. For example,a collision provokes a negative response,a
completed task would be positive.
? ?ove forward another ten years
to 2030 and you get to generation three. This robot can build internal
simulations of the world around it. Before beginning a task, it can imagine what
will happen in order to predict problems. If it has a free moment,it can replay
past experiences and try variations in order to find a better way of doing
things next time. It could even observe a person or another robot performing a
task and learn by imitation. For the first time,we have here a robot that can
think.
? ?By the time we get to generation four in 2040, Moravec
predicts that robots will be able to match hu- man reasoning and behaviour;
generalise abstract ideas from specific experience; and, conversely, compile
detailed plans of action from general commands such as’earn a living’ or ’make
more robots’
? ?The Moravec manifesto(宣告)runs something like this.
As robots start to become useful in generation ?one,they’ll begin to take
on many tasks in industry. Driven by the availability of this cheap and tireless
?labour force,the economy will boom and the demand for robots will grow so
rapidly that they will soon become low-cost commodity items. So much so that
they’ll move into the home,where the domestic robot will relieve us of many
chores.
? ?With increasing automation in generations two and three,
the length of the average working day will plummet,eventually to near zero. Most
people will be unemployed as robots take over not just primary industry, but the
service economy too. Moravec sees the fourth generation as an opportunity to
surpass our human limitations.
? ?These future machines will be our
"mind children". Like biological children of previous generations, they will
embody humanity’s best hope for a long-term
future. |
What will be the distinctive feature of the second generation robots?
A:They will be able to learn by themselves B:They will be able to recognize speeches and texts C:They will be able to predict problems D:They will be able to match human reasoning and behaviour
