Procedia Computer Science, 2018
The health service sector has been continuously trying to improve the service given to the people in need of mobility assistance. As a result, more developers have been directed towards robotic wheelchairs. A robotic wheelchair is an intelligent wheelchair that has capabilities of navigating, detecting obstacles and moving automatically by utilizing sensors and artificial intelligence. We have developed a Robotic WheelChair for the quadriplegic patients for mobility assistance operated using the head gesture. The Robotic WheelChair includes accelerometer sensor, gyroscope sensor, ultrasonic sensor, relay, battery, DC stepper motor and raspberry pi. The MPU 6050 sensor detects the movement of the head and the signal is transmitted to the Pi.The controller processes the signal and enables the motion of wheelchair for its navigation. The ultrasonic sensors help to avoid obstacles, using the environment information gathered during navigation. The wheelchair is designed in a cost-effective way but ensures safety, flexibility, and mobility for the users.
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.
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.

And in day to day life of handicapped peoples which are physically ill, faces many problems in their daily life routines. They are not able to stand alone , they need support for every work. So this study develop their lifestyle and also to reduce these difficulties of handicapped peoples with the minimum cost. The overall framework of this project is to be helping handicapped peoples for storing their freedom. With using developed technology, project goal is to help those peoples who are not able to walk due to physiological or physical illness. And there is recently extensive research on computer controlled chairs for physically handicapped persons.
– Robots of the future should communicate with humans in a natural way. Hence, we are especially interested in hand motion based gesture interfaces. The purpose of this study was to present a reliable means for human-computer interfacing based on hand gestures made in three dimensions, which could be interpreted and adequately used in controlling a remote robot's movement. In this paper we discuss the development of a novel architecture of an intelligent wheelchair working on wireless hand gesture control and not by the usual method of keypad for the physically handicapped people. Unlike others before it, this project also has a distress call system (GSM) to alert the concerned people or family in times of necessity for the person, by the person himself/herself from an alert switch or when there is any sudden detection of edge or staircase during backward motion, thus saving the chair from accidents. The locomotion of the wheelchair is controlled by a MCU (microcontroller). The physically handicapped people will have the option of controlling the system through hand gesture wirelessly from ranges up to several meters and will have the independence of using the wheelchair without the help of any other people.
