Driverless technology is quickly progressing, with many cars being tested on roads around the world. Now, researchers in Singapore are testing a different kind of self-driving vehicle - a scooter. The scooter has four wheels and a single seat. It can move at speeds of up to six kilometers an hour. It is equipped with sensors to help it avoid people and objects. The scooter was developed at the National University of Singapore. Researchers with the Massachusetts Institute of Technology (MIT) also took part in the project. This experimental vehicle was designed for people who cannot, should not or do not want to drive a car. It could help older adults, the disabled or people who are too young to drive. The scooter can be used outside or inside buildings. Marcelo Ang is with the Department of Mechanical Engineering at the National University of Singapore. He says the scooter can be especially useful for people who use wireless devices while walking on city streets.
