As
cities continue to grow at a dizzying rate, commuters are constantly
battling ever-increasing congestion on the roads and a lack of parking,
just to get to work.
But now a
team of German engineers have come up with an ingenious solution -- a
"flexible" electric vehicle capable of shrinking, driving sideways
(think like a crab) and turning on a dime.
The EO Smart Connecting Car 2
is an innovative design from DFKI Robotics Innovation Center, based in
Bremen, Germany, where a team of software developers and designers, as
well as electronics and construction engineers, have been refining the
smart micro car project for the last three years.
First
announced in 2012, the team have moved onto their second iteration of
the vehicle. It drives like a traditional car but because each wheel is
powered by its own motor, it also has the capability of driving
sideways, allowing it to slide into tight spaces in urban areas where
parking is limited, explains Timo Birnschein, project manager for the
vehicle.
He adds: "The whole process -- the transition between normal driving and driving sideways -- takes about four seconds."
Shrink and drive
The
prototype has a top speed of 65 km/h (or 40mph) and can travel 50 to 70
kilometers (30 to 44 miles) on a single four-hour full charge of the
battery. But it's the two-seater's ability to shrink to around 1.5
meters in length that has the team excited about its uses in future
cities, says Birnschien.
"It is able
to reduce it's own size by about 80cm, which makes it almost as small as
a bike in length. And with this kind of feature you can go into very
tiny parking spaces," he says. "You are still able to turn on the spot,
you are still able to drive sideways and you are still able to connect
to charging stations, for example."
Looking like part "Transformer" and part
DeLorean out of "Back to the Future," the car reduces its size by partly
folding itself. It shifts the rear axle to the front and slides on a
set of rails which raises the interior upwards, while still remaining
comfortable for the passenger.
Touted
as a "micro car for a megacity," the team are working hard to make their
vehicle roadworthy and envision it as a communal public resource,
similar to existing urban car-sharing schemes. The idea is that when you
need a car, you could head to your nearest docking station and select
the vehicle that's charged enough to drive the distance you need. It
would then detach itself and you would be on your way.
"[It]
is very comparable feature-wise to the first prototype," says
Birnschein. "The second version is much more reliable and almost
road-legal. It's not really, but it's almost there and we are trying to
bring this car to the road -- but it's a big hassle to be honest because
we have so many new technologies in the car that the technical advisory
guys are skeptical."
He adds that the
team have invited several manufacturers to test drive the vehicle, with
positive response, but the enthusiasm ends there.
"The
problem is for most car manufacturers, they are not really interested
if they didn't invent it themselves. They may buy from Bosch or Siemens
or whatever, technology parts like ESP and other things, but not
complete systems."
But his team remain
undeterred as they continue working on autonomous features like auto
pilot and self parking. Meanwhile Birnschein likens the situation to the
rise in smartphones over the last decade -- from non-existence to
oversaturation.
"It will be the same
with computer power and autonomy," he says. "In the next 10 years we
will most likely see autonomous cars from big car manufacturers --
Mercedes S class will have autonomous functions within three or four
years. Some of other manufacturers like GM announced they will have
semi-autonomous cars by 2020. And many other car manufacturers are
already working on this type of technology.
"They
are driving all the time on the autobahn with autonomous vehicles. I
believe it will be coming -- it will be there within the next decade."
