Abstract

Most wheelchair users have limitation mobility when using a wheelchair. People who have to use wheelchair for a living are at higher risks of accidents due to their inmobility. This is most likely due to road conditions, things getting stuck in the wheels or simply accidentally hit a person or something in their way. These mishaps can be extremely dangerous, resulting in serious injuries or even death. The goal of this paper is to assess the efficiency of deploying ultrasonic sensors as a wheelchair with obstacle detection system and to help solve the problem for the impaired. To identify items in a wheelchair’s blind region, the researchers employed a combination of ultrasonic sensors and an Arduino Uno. The system was tested in a variety of environments, including daytime and evening, inside and outside of a building and its performance was evaluated in terms of detection rate and reaction time. The findings demonstrated that the system was capable of detecting things on the wheelchair with a high detection rate and a quick response time. This study gives useful insights into the design and implementation of wheelchair obstacle detection systems to make everyday life easier for those who have disabilities.
