Self-driving car pioneer Sebastian Thrun has shifted his gaze to the skies, as his Silicon Valley online school Udacity launches what it calls the first "nanodegree" in flying car engineering.

With companies from Airbus and Amazon to Uber throttling up development of their own autonomous aerial vehicles, Thrun believes “in a few years time, this will be the hottest topic on the planet”.

As usual, Thrun intends to be on the cutting edge of this emerging technology.

The 50-year-old PhD computer scientist and former Stanford University professor co-founded Udacity in 2012 and says the online school’s self-driving car program has attracted 50,000 applicants since 2016.

He expects the new flying car curriculum, which opens in late February and begins taking applications on Tuesday, to draw at least 10,000 students.

Udacity is offering two 12-week terms, at $US1200 ($A1680) each, including a course in Aerial Robotics and one in Intelligent Air Systems, that provide an online certification in a fraction of the time of a traditional degree course.

In an interview, Thrun said his motivation in creating the flying-car program was similar to what drove the school’s widely publicised self-driving car course.

Thrun said “it’s almost impossible to hire qualified people” to design and engineer future vehicles, both terrestrial and aerial, that employ advanced technology, including robotics, artificial intelligence and machine learning.

“There is a huge shortage of engineers. There are plenty of smart people – the missing link is education,” said Thrun, who headed the team that launched Google’s self-driving car project, since renamed Waymo.

Thrun remains an adviser to Google parent Alphabet Inc and retains close ties to Alphabet CEO and co-founder Larry Page.

Page is an investor in Kitty Hawk Corp, a two-year-old start-up whose stated mission is “to make the dream of personal flight a reality”. Thrun is chief executive of Kitty Hawk and a co-owner.

Kitty Hawk’s first prototype, dubbed the Flyer, is not exactly a flying car but more of a one-person drone that is capable of vertical take-off and landing and does not need wheels.

“‘Flying car’ might be a bit of a misnomer – more of an attention grabber,” admits Thrun, who said he has been working with Page and others to develop autonomous aerial vehicles.

“It feels like science fiction now,” Thrun said. “But with Google and Amazon moving in, there is going to be enormous activity around this in the next year or two.”
