A Position Detecting System Using Supersonic Sensors for Omnidirectional Wheelchair Tennis

The wheelchair with good performance for the aged and disabled is attracting attention from the society. Also, the wheelchair can provide the user with many benefits, such as maintaining mobility, continuing or broadening community social activities, conserving energy and enhancing quality of life. The wheelchair body must be compact enough and should be able to make different movements in order to have many applications. In our previous work, we presented the design and implementation of an omnidirectional wheelchair. In this paper, we propose a position detecting system using supersonic sensors. The proposed system can find correctly the wheelchair position for collision avoidance.
