In modern times like this, many wheelchairs have been developed with various controls, ranging from manual ones, namely by being pushed other people or using their hands to turn the wheel, automatic such as electric that use joysticks and Electromyography control. The control of electromyography signal utilizes muscles can still be used move wheelchair, in this case, hand muscles. a Bluetooth w...

Electric wheelchairs are designed to aid paraplegics. Unfortunately, these can not be used by persons with higher degree of impairment, such as quadriplegics, i.e. persons that, due to age or illness, can not move any of the body parts, except of the head. Medical devices designed to help them are very complicated, rare and expensive. In this paper a microcontroller system that enables standard...

The purpose of this study was to evaluate the effects of three different control methods on driving speed variation and wheel slip of an electric-powered wheelchair (EPW). A kinematic model as well as 3D dynamic model was developed to control the velocity and traction of the wheelchair. A smart wheelchair platform was designed and built with a computerized controller and encoders to record whee...

[Purpose] The purpose of this study was to investigate adapting wheelchair cushions to hemiplegic individuals based on trunk function and a single-leg driving motion. [Subjects and Methods] Subjects were 18 hemiplegic adults who were able to use and sit up in a wheelchair. Subjects were grouped into Able and Unable groups according to the Functional Assessment for Control of the Trunk (FACT). T...

Wheel chairs are the way of reincarnating life in the lives of physically disabled people.A dependent user recognition voice system and ultrasonic sensor systems has been integrated in this wheelchair. In this way we have obtained a automatic wheelchair which can be driven using voice commands and with the possibility of avoiding obstacles by using ultrasonic sensors . The wheelchair has also b...

This article presents a summary of current state of smart wheelchairs. An assistive technology known as wheelchair is used to deal with loss of mobility for the patients who are not able to walk normally due to some injury or some other age related walking disabilities (permanent or under treatment). There is a vast development in the field of wheelchairs. Researchers are going on to develop re...
