This document summarizes the development of a solar-powered tricycle designed for disabled individuals. It discusses problems with existing tricycle designs, such as requiring large effort to pedal and lacking gear ratios. The proposed design uses a solar panel to charge batteries that power a BLDC hub motor and controller. It is intended to be easier to use, more efficient, and cost-effective compared to traditional tricycles or electric tricycles that rely solely on batteries. The document reviews several other research papers on solar tricycle designs and their performance testing to inform the new proposed design. The goal is to provide disabled individuals with independent and sustainable transportation.
