AI race car vs. human: Who wins?

Racing on the track that staged the opening two rounds of the 2017-18 Formula E championship, the task for both human and robot was complicated by the confines of the street circuit.

“It’s quite scary because it’s very narrow — there was no room to maneuver,” Shields explained.

“Going into one of the chicanes is insanely tight, and of course if you get it wrong you are in the wall. You have to get it right every time.”

For Roborace, it wasn’t just the track but Hong Kong’s unique topography that posed problems.

“This was our first time of running our completely new AI Driver software in a built-up urban environment,” Roborace’s CTO Bryn Balcombe told CNN via email.

“The urban canyons created by the tall skyscrapers cause disruptions to GPS which are difficult to replicate in a testing environment.”

Before completing a flying lap Roborace engineers deploy DevBot at low speed in what they call “explorer mode” where track data is gathered using state-of-the-art sensing equipment including LIDAR, radar, ultrasonics and cameras.

Once the track has been scanned, the information is processed by an AI computer (a NVIDIA Drive PX2) that uses complex algorithms to determine the fastest route (the racing line) around a track.

“Compared to a human, the main challenge is how fast it takes for the AI Driver to adapt and learn a new track,” Balcombe said.
