Many people have heard of autonomous cars, but what about self-driving wheelchairs? The self-driving wheelchair is the latest invention of the Computer Science Artificial Intelligence Lab (CSAIL) of the Massachusetts Institute of Technology’s (MIT). The invention integrates LIDAR (light detection and ranging) scanners and 3D mapping technology, allowing those with special needs and mobility issues to travel with ease.

Equipped with a mapping technology developed by CSAIL in 2010, this self-driving wheelchair is able to create a 3D map of the surrounding environment with the help of LIDAR scanners. By using the wheelchair joystick controller, users can draw a designated path. A small scanner at the front of the wheelchair will detect obstacles along the path. Once the system detects an obstacle, the wheelchair will automatically slowdown and adjust its position to bypass the obstruction.

Although still in testing phase, the prospects of self-driving wheelchairs are optimistic. Given further refinement, it is believed that the invention can be used in aiding transportation of patients within hospitals.
