Resumen

Wheelchairs are essential for people with reduced mobility. Motorization of these devices can provide an increase quality of living and independence for their users. However, the cost of electric wheelchairs makes them inaccessible to users from developing countries. To address this issue, a low-cost modular kit is proposed, designed and manufactured. The mechatronic design of the kit includes the mechanical design of the components as well as dimensioning, the selection of electronic components, as well as the incorporation of IoT technology to be able to control it using a smartphone if necessary. The resulting modular kit proves to be useful as it can be rapidly installed on a commercial wheelchair without modifying its structure. Preliminary tests of the functional prototype show the wheelchair can provide enhanced mobility to the user, a low turning radius for narrow spaces, as wells as the ability to easily climb up and down on ramps.
