Design of a Multifunctional Electronic Module Adaptable to a Motorized Wheelchair for People with Motor Disabilities

Attention to the disabled has been an issue of interest to the different areas of science and technology. The development of new technologies focused on disability is of vital importance as it allows improving the quality of life and incorporation into society. This paper presents the development of an electronic module adapted to a motorized wheelchair, which allows a person with some motor disability, in particular with spinal cord injury, to move. The module has a multifunctional capacity to direct the chair, by means of the inclinations of the head detected in an accelerometer implanted in a headset, through voice commands, through a mobile application developed for devices that have the Android operating system. For people who have movement only in their hands, a Flex sensor is included, as well as a myoelectric sensor that reacts with the contractions of a muscle.
