Design and Development of a Low-Cost Multi-functional Wheelchair with Patient Monitoring and Obstacle Detection

Abstract

In general, a disable person needs assistance for self-movement. The objective of this project is to develop a low-cost prototype of a wheelchair with several characteristics that can be used by the ill and the disabled. In this paper, a low-cost multi-functional wheelchair with patient monitoring and obstacle detection is proposed. The multi-purpose wheelchair is built with all the characteristics required to guarantee safety and ease of use. A joystick is used to steer the wheelchair in any direction, and a push button is used to convert it from a chair to a bed. Using a temperature sensor, heart rate sensor, ECG, and blood pressure (B.P.) sensor, we can keep an eye on the patient, and a microcontroller is used to display this data on a screen. Every time the parameters exceed the threshold values, an alarm message is automatically delivered through GSM module to the phone of the person who has been informed. The patient’s health state is checked via IoT. The wheelchair uses an ultrasonic sensor to identify obstacles. A medicine reminder system is also designed to remind patients to take their medications. With a Wi-Fi camera, the individual is being watched. To present all the facts and amuse the impaired person, a display is employed. The user-friendliness of the multi-features wheelchair is being improved to lessen the strain on patient attendants. Every individual who is ill or disabled will feel more confident as a result of being independent.
