Driverless car makers are discovering a unique problem as they begin
to test the vehicles in Australia.
It turns out the unusual way that kangaroos move completely throws off
the car's animal detection system.
"We've noticed with the kangaroo being in mid-flight ... when it's in
the air it actually looks like it's further away, then it lands and it
looks closer," Volvo Australia's technical manager David Pickett said.
Because the cars use the ground as a reference point, they become
confused by a hopping kangaroo, unable to determine how far away it is.
But Mr Pickett said it was even more complicated than that.
"First we have to start identifying the roo," he said.
"We identify what a human looks like by how a human walks, because
it's not only the one type of human — you've got short people, tall
people, people wearing coats. The same applies to a roo.
"If you look at a roo sitting at the side of a road, standing at the
side of a road, in motion, all these shapes are actually different."
The company nailed down their large animal detection software, first
tested on moose in Sweden. But the research team, who were sent to
Tidbinbilla Nature Reserve in Canberra 18 months ago to study roos,
are still solving the Australian problem.
"It's quite interesting for them," Mr Pickett said.
He said it would not delay the eventual rollout of driverless cars in
Australia, but it was critical to solve the problem before they were
introduced.
According to the NRMA, there were more than 16,000 collisions with
roos a year, with nearly 1,000 of those in the bush capital - the
number one hotspot for roo collisions in the country.
Road trains, unsealed roads among other Aussie challenges
In addition to difficulties detecting roos, the cars will need to be
adjusted for a few other Australian quirks before they are rolled out.
Australian Driverless Vehicle Initiative executive director Rita
Excell said Australia's many unsealed roads, its unmarked highways,
and the huge road trains that barrel down regional highways were among
the challenges.
"There are some things you don't find in other countries. If you've
got a car passing something like [a road train], it needs to
understand what that is," Ms Excell said.
But while regional Australia's road infrastructure may need some work
to be driverless car-ready, Ms Excell said Australia was well
positioned to be one of the first places for the vehicles.
"The maturity is much further along than maybe is publicly aware," she
said.
