Never
mind C3PO, Marvin the Paranoid Android or Doctor Who's tin-dog
K9 - the future of robots and much, much more may be right
here on our doorstep in Bradford.
Take
a look at the brochure for the University of Bradford's Department
of Cybernetics and you'll find there's a lot more on offer
here than a job ticket. Cybernetics, Virtual Worlds and Animatronics
- they seem to be the very stuff of science fiction but come
to Bradford and you can work on these seemingly mind-blowing
topics here and now.

| I,
Robot is now on general release |
In
the Hollywood version of reality robots are still very much
the future yet they have been with us in one form or another
for quite a long time. In 400BC Archytas of Tarentum built a
wooden dove that could flap its wings and fly. Back in the 16th
century - long before we were asking whether Harrison Ford's
Blade Runner was human or not - a certain Hans Bullman had created
androids to play musical instruments.
In
1921 Czech writer Karel Capek published his play RUR in which
human-like machines are created to replace human workers and
the word 'robot' was born. From Metropolis to Short Circuit,
Terminator and now, I Robot, starring Will Smith, we are as
fascinated as ever by the idea of these increasingly complex
machines and how they interact with their makers.

| Forget
Doctor Who's K9 - today's canine robots should like real
dogs. |
So,
do robots really matter? Are they useful tools acting in the
service of humankind or could they in the future turn round
and destroy the hand that created them?
Bradford
University's Dr John Baruch spends his life developing robots.
He is currently building two telescopes as second generation
interactive robots, one in Tenerife and one in Australia,
using web-based technology. We went to see him to find out
how far fact has now caught up with fiction.
Already,
it seems, woman's, or even man's, best friend could be a robot.
Students at Bradford can now study animatronics and may go
on to design models for the film industry or even shopping
malls. Dr Baruch says we should forget Doctor Who's canine
companion: "They want them now to look like real dogs
- K9 was just a robot looking like a robot. Most of the robots
you buy look like robots but there's still an interest in
having things that look like people or particular animals."

| Marvin
"the paranoid android" - it may be possible
to give robots character but will they ever have brains
the "size of a planet".? |
Nor
does it stop at looks: "Character in robots is something
people can recognise. What we are seeing now on computers
and other devices is the generation of characters that people
feel comfortable interacting with...They'll never be very
clever but they are very willing."
But
if robots are so willing, to what extent can they be used
against humans? Dr Baruch comments: "Eventually, yes.
I think the I, Robot film does raise real issues but I think
we are a very, very long way from robots being able to think
like human beings and being able to behave like humans in
what they do."
Robots
are used for military purposes but Dr Baruch says we are still
a long way from having armies of impregnable soldiers: "I
think you are much more likely to have robot tanks that fight
against humans...I think people are very clever and robots
are pretty stupid."
I,
Robot is loosley based on the book of the same name by pioneering
sci-fi author Isaac Asimov who set out his three laws of robotics
but Dr Baruch does not seem to think these are particularly
useful: "I think Asimov was one of those people who thought
you could make robots like human beings eventually. I think
human beings are so complex with so many different drives
that motivate them. It takes human beings 16 years to grow
up and a lot of training goes on, an enormous amount. Who's
going to train robots for 16 years..?
"You
can clearly put experience into a very big memory. Human memory
is something no-one's really managed to duplicate. Humans
walk around and remember where they've been. They remember
millions of places probably and lots and lots of faces and
that's way beyond what machines can do."
We
asked Dr Baruch what questions he thinks are now at the frontier
of cybernetics. He explains: "Cybernetics is about complete
systems and how they can work and there are a number of big
questions that nobody really knows the answer to. If you look
at the laws of physics human beings shouldn't exist, so how
is it on a system like the earth we get self-organising molecules
that eventually generate reproducing life?

"I
think that's the question that science will eventually solve
and I suppose people who are religious will say, 'Ah, well.
They'll never solve it,' but throughout history religion and
science have been two different sorts of animals. You either
believe or you don't believe and if you believe, whatever
science finds out, the religious people find a way round it.
That's fair enough - it's different - it's a different thing.
Religious people would say they believe in it and that's good
enough while science would say, 'What does God weigh, how
long does she or he sleep for?' and all these sort of questions.
These are valid scientific questions and we've seen in the
past that religion has said the world is flat at one stage
and they've said the earth is the centre of the universe at
another, and when science showed these were wrong then it
may have taken a few hundred years but religion was able to
cope with it.
"We've
already taken things like atoms and molecules and built little
things like viruses that are part of life and I think they'll
go a bit further and they'll be able to build other things.
How systems self-organise to generate life is a very difficult
cybernetics problem but it's a very important problem because
things like that happen in life all the time and we'd very
much like to understand it."
In
the meantime Dr Baruch feels that developments in cybernetics
and robotics can have real benefits: "We're on the verge
of being able to give people a pair of hips instead of a wheelchair.
You just sit on these hips with legs beneath and you just
walk. They'll take you upstairs on buses."
So,
if you've got a bit of science and a bit of computing knowledge
but, most of all passion, for projects which could take you
to the very frontiers of science, then Bradford may be the
place to be.
