Desenvolvimento de um kit didático para estudo de robótica

Abstract

Robotics is a field of great relevance in modern society, and its study in higher education courses faces several challenges. In this context, this work presents the development of a didactic kit for the study of robotics, focusing on the control of a robotic arm using joysticks and wireless communication. The objective was to create an integrated solution that would enable intuitive remote control of the robot, making the educational process more practical and dynamic for students. The system is composed of a robotic arm with 3 degrees of freedom, a control board that captures the position values from the joysticks, and an actuator board responsible for moving the robotic arm’s servomotors based on the received data. Communication between the boards is carried out using the ESP-NOW protocol. Additionally, the work includes the design, execution, and implementation of printed circuit boards (PCBs). During development, challenges were encountered related to the accuracy of joystick position readings, control of servomotor speed, and the manual fabrication of the PCBs. These challenges required specific solutions, which were overcome through adjustments in design and testing. The results confirmed the system’s functionality and effective integration between components. The project demonstrated the feasibility of remotely controlling a robotic arm using accessible technologies and efficient control techniques, contributing to the practical and interdisciplinary teaching of robotics.
