A novel strategy for controlling the movement of a smart wheelchair using internet of things

Quadriplegia is a medical condition characterized by partial or complete paralysis of the four limbs and torso. Paraplegia is a variant of quadriplegia and is an impairment in motor or sensory function of the lower extremities. An automated wheelchair is a step taken with an intention to make a difference especially to the lives of these sections of people with restricted mobility. The different modes of control for the movement of the chair are made available in a modular form and can be incorporated by the user based on specific needs. Apart from the controls like joystick, chin control, voice activation, control through head movement, through calls made using a mobile, this chair can also be remotely controlled through the internet. Raspberry Pi is used as a master controller for both joystick as well as internet control. This paper specifically presents the details of control of the smart wheel chair through the internet using the technology of internet of things.

I. Introduction

Technology applied does make a huge difference to the world of people with restricted mobility. Internet of things is one such development. The care takers of the affected are also relieved by the fact that, the availability of technological advancements makes life easier. The control of the wheelchair can be accessed by logging into a website. The wheelchair is enabled for control from anywhere in the world. The whole objective of this work was to develop an economical, convenient, extensible and fool-proof system for an automated, electrically powered wheelchair catering to the needs of quadriplegics and paraplegics. The unique features of the smart chair are that, •

Individual modules that can be incorporated into any wheelchair which enables the patient or guardian to choose only what they feel is required thereby reducing the expenditure.

•

The controller is so developed that any module that is developed at a later stage can be integrated on to the wheelchair with ease.

•

Connectivity to the internet
