Researchers at the Singapore-Massachusetts Institute of Technology (MIT) Alliance for Research and Technology (SMART) have spent the last several years developing autonomous vehicles as part of the Future of Urban Mobility Research Program.
Since the public trial, the group has introduced a self-driving city car, a self-driving scooter, and a self-driving wheelchair, each of which was designed in three phases.
In the first phase, the vehicle was converted to drive-by-wire control, which enables a computer to control driving functions.
In the second phase, the vehicle drives through its operation environment and creates a map using features detected by its sensors.
Finally, the vehicle uses the map to determine a path from the customer's pick-up point to the customer's destination and drives along the path, localizing continuously to avoid obstacles.
The vehicles also use traffic data sourced from Singapore's Land and Transportation Agency to model traffic patterns.
Last April, the researchers conducted a public trial at MIT to test their self-driving scooter's ability to drive indoors as well as outdoors.
The researchers envision a future in which a mobility-impaired user could schedule combinations of autonomous wheelchairs, scooters, and cars to reach their destination.
