A team of 10 researchers is making improvements to Singapore’s first self-driving wheelchair after a pilot trial at Changi General Hospital (CGH) last September.
The autonomous vehicle is a project involving the Singapore-MIT Alliance for Research and Technology (Smart), Massachusetts Institute of Technology and National University of Singapore.
The wheelchair is able to detect stationary and moving obstacles, and is not programmed to reverse – a built-in safety feature.
Professor Daniela Rus, the principal investigator, explained the need for such a wheelchair.
She said nurses in hospitals spend a considerable amount of their time looking for wheelchairs and carts for their patients. “More time can be spent on patient care and less time on logistics,” she said.
The electrical engineering and computer science professor said that the self-driving wheelchair will also help hospital patients navigate “complex networks of hospital hallways”, and help move patients after they have completed surgical procedures.
Smart got CGH on board to provide them with a testing ground. However, there are no plans yet for implementation.
SATS also unveiled its version of semi-autonomous wheelchairs during a two-day event that started on Wednesday. The ground handling firm and food solutions provider said the wheelchairs will raise productivity and efficiency.
