Electronic device adaptable to motorized wheelchair as smart navigation system

Technological development offers new opportunities for people with disabilities, to improve their quality of life and increase their inclusion in society. Motor disability is an alteration that affects, at different levels, the movement or manipulation of a person. This paper presents the design and construction of the second version of an electronic device adaptable to a motorized wheelchair that serves as an intelligent navigation system. The first version of the electronic device only allowed for control of the wheelchair through head movements and voice commands. In this new version, the previous functions were improved and two new functions were incorporated. Muscle flexion and muscle contraction increase the options to control a motorized wheelchair by people with greater limitation of movement. The tests carried out demonstrate the viability of the prototype.
