What is clear is that a huge global event can focus the minds of those developing such technology, with Tokyo-based robotics outfit ZMP and local taxi firm Hinomaru Kotsu determined to have a robot taxi service up and running in time for the Japan-hosted Olympics in 2020.
The world's first autonomous taxi service begins operating in Tokyo, Japan. The pilot project will run until September 8, with full commercial operations expected to start in 2020, when the city hosts the 2020 Summer Olympics.
