Recently, Taiwan and many developed countries have been experienced an emergence of growing aging population and decreasing working population and birth rate. The number of home-caring workers in need has surpassed that of available working force. Furthermore, the expense of home-caring elders will substantially increase. The employment of foreign workers is just a temporary solution. It is the...

The design of brain-computer interface for the wheelchair for physically disabled people is presented. The design of the proposed system is based on receiving, processing, and classification of the electroencephalographic (EEG) signals and then performing the control of the wheelchair. The number of experimental measurements of brain activity has been done using human control commands of the wh...

A wheelchair user's mobility may be hampered by narrow doorways and restricted turning spaces. Mobility may be improved by undertaking expensive building alterations in the wheelchair user's own home and work environment. However, other environments, including modes of public transport, may still present considerable difficulties. One way of improving mobility is to reduce the overall width of ...

The electric wheelchair is an effective machine for people with lower limb disability. The user controls the wheelchair by a joystick that helps the user to navigate the wheelchair along the desired path. Suppose the user on the wheelchair wants to operate the computer for his jobs or enjoyment, it is preferable for the user to be able to operate the computer without transferring from the wheel...

this paper presents a robust fractional order controller for flexible-joint electrically driven robots under imperfect transformation of control space. the proposed approach is free from manipulator dynamics, thus free from problems associated with torque control strategy in the design and implementation. as a result, the proposed controller is simple, fast response and superior to the torque c...

PURPOSE This study was conducted to compare the performance of three types of chairs in a low-resource setting. The larger goal was to provide information which will enable more effective use of limited funds by wheelchair manufacturers and suppliers in low-resource settings. METHODS The Motivation Rough Terrain and Whirlwind Rough Rider were compared in six skills tests which participants co...

A survey among 127 wheelchair users was conducted to characterize wheelchair occupant restraint usage patterns, restraint deficiencies, user characteristics, and essential wheelchair occupant restraint design parameters for when individuals travel in motor vehicles while seated in their wheelchairs. Survey respondents value independent travel and seem generally interested in the use of an occup...

Wheelchair ergometer testing is used to characterize wheelchair propulsion mechanics. The reliability of kinematic and kinetic measures has not been investigated for wheelchair ergometer testing. In this study, test-retest reliability of biomechanical measurements on a wheelchair ergometer was determined during a submaximal endurance test. Ten nondisabled subjects (seven male, three female), in...

in this article a new and an accurate method for kinematic and dynamic analysis of a parallel robot 3prs and a hybrid robot (parallel and serial) 3prs-rrp are presented, which is based on the denavit-hartenberg transformation matrix algebra. first, basic properties of various kinds of robots are compared, and then the denavit-hartenberg parameters and their table are introduced. next, the metho...

An Australian Standard for Wheelchair Occupant Restraint Assemblies for Motor Vehicles has been produced. Titled Australian standard 2942-1987, Wheelchair Occupant Restraint Assemblies for Use in Motor Vehicles, it establishes design and performance requirements for these restraints, and includes details of dynamic testing procedures. Under the Standard, a lap belt is the basic occupant restrai...
