Wheelchair Controlled By Head Motion

International journal of innovative research in electrical, electronics, instrumentation and control engineering, 2023

The Head motion controlled wheelchair is propelled by means of an electric motor rather than manually. Quadriplegics are one of the many physically disabled people that require such wheelchairs. They have paralysis of all four limbs and the torso that may be caused due to spinal cord injuries, strokes or cerebral palsy. They have no control over their hand movements and cannot grasp things or perform motions that might allow them independence over their movements. The tilting movements of the head in the four directions-forward, backward, right or left-would cause the wheelchair to move in the signaled directions. Quadriplegics rely on power wheelchairs for mobility, but the hands-free controller systems currently available are obtrusive and expensive. Smart wheelchair is an innovation that has an intention to create a difference for the activities of the people who are restricted by movement. This is an idea to ease those patients, who cannot perform hand movements in a way that can move a wheelchair. In this paper, we discuss about the working model of a head motion controlled wheelchair using Internet of things (IoT). The movement of the head is detected by MPU6050 and the signal is transmitted to the microcontroller. Then controller processes the signal and motion of wheelchair is enablesthe navigation. The wheelchair was capable of moving left, right, forward and backward direction and it is capable of doing tasks like navigation, obstacle detection, etc. using sensors and intelligence.

In this quick moving, ravenous world, individuals need to refresh and create themselves. Individuals with Quadriplegia cannot move any of their appendages and are hence constrained in their capacities of interfacing with their condition. In any case, a significant number of them can even now move their heads which can be used for the improvement of assistive gadgets. This sort of clients experiencing quadriplegia requires exceptional wheelchairs as opposed to utilizing customary ones that are constrained by joystick, since they are incapacitated underneath their neck. This undertaking plans to head direction controlled savvy wheelchair so as to improve their everyday exercises of living, with no help. The proposed frameworkutilizes accelerometer module which is given to Arduino Nano. As per the orders, wheelchair moves. Alongside obstruction recognition is likewise done utilizing ultrasonic sensor. Patient monitoring framework incorporates temperature and pulse estimation with infor...

Wireless Head Motion Controlled Wheel Chair for Disabled People

This paper discusses an indigenously built handfree wheelchair for visually impaired persons. The proposed system is based on a Head Motion Recognition technique using an Acceleration Sensor. Conventional physical wheelchairs are generally powered by joysticks or hand gesture devices that can not address the needs of an almost entirely disabled adult who has limited limb movements and can barely move or turn his head. The acceleration sensor is used for head gesture recognition and the Zigbee module is used for smart wireless control. Through the adjustment of the head motion, the information goes wirelessly to the microcontroller dependent motor driving circuit to control the rotation of the Wheel Chair in five different modes, including FRONT, BACK, RIGHT, LEFT and a special STAND locking device. The proposed system is assembled using components obtained from the local market and checked in the laboratory for efficient performance, the test results are included in this article.

Modeling and Fabrication of Smart Robotic Wheelchair Instructed by Head Gesture

Indonesian Journal of Electrical Engineering and Informatics (IJEEI), 2021

The confronting problem faced by the handicapped, paralyzed, disabled, and quadriplegic people is their independent mobility. They need external assistance to perform their daily life activities. This paper aims to solve that problem by smart designing and deployment of the robotic wheelchair for those who cannot perform their voluntary activities and movements. The proposed automated wheelchair comprises two parts; the first part is the user's helmet that works as a master device, and the second part is a slave device, a smart wheelchair. The master device consists of an accelerometer, microcontroller, and wireless transmitter, in which the Accelerometer recognizes the movements of the user's head and transmits the signal according to the tiltation of the user's head. Besides this, the slave device consists of a wireless receiver, microcontroller, Gyroscope, power MOSFETs, and DC geared motors mounted on a smart wheelchair, which response as per the instructions of the master device. Furthermore, the paper also provides a brief construction of this mechatronic and amphibian system using static and dynamic equations.

Development and Testing of Intelligent Wheelchair Controller for Quadriplegic Patients

Advances in Science, Technology and Engineering Systems Journal, 2018

In this research paper, the development and evaluating of a smart controller for electrical powered wheelchairs are presented. The controller aimed to assist quadriplegic, paralyzed, and handicap patients who cannot use their hands to drive an electrical wheelchair by using a joystick controller. Two sub control units have been combined in one hybrid system to create the current version which are voice, and head tilt controllers. They are activated and operated in parallel at the same time to allow the wheelchair user to choose the preferred control method. The voice controller is activated by the user's voice command to control the wheelchair instead of a joystick. The head tilt controller uses the user's head motions to create control commands instead of the joystick controller. The head tilt controller design is based on using two embedded MEMS orientation detection modules as input measurement units. The system uses a modern low power consumption microcontroller to analyze the received information and data from inputs and creating the prompt control commands and send it to the wheelchair motors driver as an output unit.
