Prototipado de un sistema de bipedestación en una silla de ruedas con la inserción de recursos para control y monitoreo remoto usando IoT

Abstract

Due to a lack of incentives for its development and the high cost of importation, people with mobility impairments do not have wheelchairs with standing systems, which deteriorates their mental and physical health because they are unable to engage in activities independently. Therefore, the objective of the present work was to prototype a standing system in a wheelchair with the insertion of resources for remote control and monitoring using IoT. The methodology implemented had a deductive approach since a study of the art was carried out for the characterization of the standing system, through exploratory research, the requirements of the prototype were characterized by obtaining a Computer-Aided Design (CAD) model, validated through a structural static analysis in the SolidWorks program, following a structural methodology the software and hardware resources were selected to provide technological resources to the prototype, then proceeded with the construction of the mechanical and electronic systems and implementation of the visual interface of the IoT platform materializing the prototype culminating with functional tests. From the results obtained, the potential impact of the prototype was highlighted by incorporating an automatic electronic standing system, achieving a minimum safety factor of 1.98 which validates the design to support the weight of a person up to 160 cm tall and 70 kg safely, a total standing cycle of 40 seconds in a stable manner reaching the characteristic standing degrees of 163° and 169°, with an energy consumption of 196.8 W and 100% efficiency of data publication on the IoT platform. In this context, it is concluded that the standing chair prototype offers advantages, including lower costs, technological integration, and safe operation in a product produced domestically.
