Architectural barriers still exists for the wheelchair users in many cities and buildings, and it is very difficult to eliminate all of them. There have been a number of wheelchairs designs that claim to overpass these barriers. The authors of this paper believe that most of these designs have serious problems related to: its low payload capacity, the lack of safety or its impossibility to over...

Most of the wheelchair users are paraplegics, who are not able to move on their own due to permanent injury in their lower extremities. These wheelchairs are four-wheeled and have certain limitations due to design and control mechanism. For example, the wheelchairs cannot move to a higher level, lift the front wheel and stay in an upright position. As a result, wheelchair users cannot reach cer...

A power-assisted wheelchair driven by dual electric-motors is required to operate on rough roads properly, where the right and left wheels encounter disturbances independently. This paper presents a synchronized motion control scheme which integrates the force sensorless controller such that the movement of the power-assisted wheelchair can maintain a desired motion path on rough surfaces. The ...

An autonomous robot based on a Wheelchair. The destination place are pre-established in the processing unit of the robot and.Although autonomous capabilities are important, the techniques required are. This article presents our new modified robotic wheelchair. The key point of the.architecture follows a behaviour-based control architecture. The wheelchair is a KIPR KISS Institute for practical ...

The Internet is becoming increasingly important in our daily lives, allowing people to exchange and receive a wide variety of data. It can be utilized ways for maximum benefit. For example, the concept Things (IoT) suggests that objects linked Internet. Based on this concept, paper, we describe creation modern smart-wheelchair accessories. These make wheelchair simple use, suitable elderly, fol...

Novel feedback control which is designed in human-friendly way is applied to power assist wheelchair. It provides this three-dimensional control of a wheelchair taking the operation situation into considerations; wheelchair needs controlling in the three dimensions: the longitudinal direction, the lateral direction, and the pitch direction. To this end, three assist controls are suggested: dist...
