Scientists are studying how insects walk, fly and navigate their
way in the world to overcome some of the obstacles in the development
of robots. The Australian Academy of Science's new Nova:
Science in the news topic ‘The buzz about insect robots'
has the latest information at http://www.science.org.au/nova .
How does a fly manouevre with such precision, a bee find its
way from flower to hive, or a cockroach move so quickly? Scientists
have recently started answering such questions, and they are
beginning to realise that insects are the superheroes of the
planet, with unique attributes that could guide the next wave
of advances in biomimetic robotics.
There are a lot of advantages in working with insects. They
are plentiful and easy to maintain in laboratories. They are
also immensely diverse, offering a wide variety of strategies
for things like movement, navigation and vision. And recent advances
in miniaturisation make the construction of insect-sized robots
possible.
Scientists have already developed six-legged robots, but have
been unable to achieve much in the way of speed. Cockroaches
are showing us how it can be done. Robotics engineers are now
hard at work designing machines that mimic, as much as possible,
the biomechanics of the cockroach .
Scientists are also studying bee vision to overcome problems
with navigation by robots, and studying insect aerodynamic techniques
to find out how insects perform their astounding aerobatics.
Many of the solutions to complex problems that nature has come
up with are magnificent in their simplicity, yet adapting even
these to our purposes will not be easy. It seems likely, though,
that robotic superheroes really will cruise the planet some day,
even if sometimes we hardly know they're there.
