The characteristics of lead-acid batteries for wheelchairs in terms of a new empirical equation for the capacity, application of the Palmgren-Miner Rule for sizing the battery, and the effect of depth of discharge on the life cycles is presented. A brief section about selecting an economical battery for an electric wheelchair is included.

This paper presents an application of image based homing for the navigation of a wheelchair. It describes which information can be generated by comparing panoramic images and how this information is used to cope with the kinematic restrictions of the wheelchair in gure 1. Figure 1: The Bremen wheelchair 1 Motivation The navigation of autonomous mobile systems (robots) is still an unsolved probl...

The goal of this research is the creation of a complete robotic wheelchair system to be used by people unable to drive standard powered wheelchairs. A complete robotic wheelchair system must be able to navigate indoor and outdoor environments and should switch automatically between navigation modes. For the system to be useful, it must be easily customized for the specific access methods requir...

This paper addresses the dynamic path planning for two mobile robots in unknownenvironment with obstacle avoidance and moving target tracking. These robots must form atriangle with moving target. The algorithm is composed of two parts. The first part of thealgorithm used for formation planning of the robots and a moving target. It generates thedesired position for the robots for the next step. ...

Optimizing mobility performance in wheelchair court sports (basketball, rugby and tennis) is dependent on a combination of factors associated with the user, the wheelchair and the interfacing between the two. Substantial research has been attributed to the wheelchair athlete yet very little has focused on the role of the wheelchair and the wheelchair-user combination. This article aims to revie...

Manual wheelchair propulsion is a straining form of ambulation, both for the cardio-respiratory as well as the musculo-skeletal system. Wheelchair locomotion implies arm work in every other activity in daily life. Compared to leg work, wheelchair arm work is much less efficient and more straining, and subsequently leads to a lower work capacity. Underlying pathology may further influence perfor...

This study examined the usage of powered seating functions, including tilt-in-space, backrest recline, and seat elevation, among a group of wheelchair users during their typical daily activities. Twelve individuals who used a power wheelchair with seating functions participated in the study. They drove their own wheelchair and used the seating functions as needed in their community environment ...

Manual wheelchair users are at great risk for the development of upper extremity injury and pain. Any loss of upper limb function due to pain adversely impacts the independence and mobility of manual wheelchair users. There is growing theoretical and empirical evidence that fluctuations in movement (i.e., motor variability) are related to musculoskeletal pain. This perspectives paper discusses ...

OBJECTIVE To examine wheelchair athletes' perceptions of wheelchair configuration in relation to aspects of mobility performance. METHODS Nine elite wheelchair athletes from wheelchair basketball, wheelchair rugby and wheelchair tennis were interviewed using a semi-structured format. Interview transcripts were analysed using an Interpretative Phenomenological Analysis, whereby emergent themes...

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...
