Initial Development of a Low-Cost Assistive Robotic Manipulator Using ESP32

This article reports the initial development of an assistive robotic manipulator designed for individuals with motor disabilities, merging theoretical approaches and practical construction methods to achieve a low-cost solution. The manipulator comprises an electromechanical robot arm structure and a control system, with a focus on the design, analysis, and load testing. The 6-degree-of-freedom robotic arm, crafted using Solid Edge software and controlled via ESP32, stands out as an accessible technology. With a dual emphasis on wide applicability and addressing the specific needs of wheelchair users with limited upper limb mobility, this research contributes to the evolving landscape of cost-effective assistive technology.
