Uber Eats rolls out self-driving robot deliveries in Tokyo

Tokyo: "Caution: robot!" chirps the green self-driving delivery vehicle as it trundles down the street to a meat cutlet restaurant in Tokyo to pick up a meal ordered on Uber Eats.

Starting Wednesday, robot deliveries will be offered in a small area of the city by the US-based food app, which hopes to eventually roll out the service more widely in Japan.

The country, facing growing labour shortages, changed traffic laws last year to allow delivery robots on public streets, and other companies including Panasonic are also trialling cute new machines to transport goods.

Uber Eats' boxy robots have square headlights for eyes and three wheels on each side to navigate kerbs as they calculate routes on their own, using sensors to avoid pedestrians and other obstacles.

Moving at up to 5.4 kilometres an hour (3.4 mph) and with flashing lights around the lid, there's a human operator on standby in case of trouble.

Like self-driving delivery services launched by the company in North America, the Tokyo robots will be limited in scope at first, said Uber Eats executive Alvin Oo.

App users must wait outside for the robot to arrive, but one day it could come to their door, he told AFP on Tuesday.

The Uber Eats robots, developed with Mitsubishi Electric and US start-up Cartken, will deliver food from just a few restaurants in the busy Nihonbashi district at first. Users cannot choose robot delivery, and if it is selected for them they can accept or decline the offer.

At a demonstration on Tuesday, the robot nearly collided with a pedestrian, but also attracted lots of attention. It's "so cute, so eye-catching", said passer-by Akemi Hayakawa. "I thought it might bump into people's feet, but people give way to it," the 60-year-old said.

"Japan has an ageing, dwindling population, with a serious labour shortage. So this is a very good idea for Japan too."
