Robotaxi
로보택시
A self-driving taxi that carries passengers and drives itself with no driver.
Overview
When you call a car with an app, a car with an empty driver's seat arrives and takes you to your destination. The car watches its surroundings with sensors such as cameras and lidar, and AI does the driving. In terms of self-driving levels, it is level 4, driving with no person inside under set conditions.
It does not drive just anywhere. It runs only inside areas where the company has finished testing in advance and received a permit. When the car meets a situation it has trouble judging, a person at a faraway control center helps. Who is responsible after an accident, weather such as heavy rain or snow, and the high cost of each car are the remaining challenges.
An everyday example
If there are driverless subways that run on fixed tracks, a robotaxi takes that driverless operation out onto ordinary roads. Roads are mixed with people and other cars, so it is much harder.
Why it matters
It is the first form of self-driving to go beyond experiments and become a paid service. News that a company has started service in a certain city is a yardstick of how far this technology has come.
