자율주행로봇 플랫폼을 위한 모듈 기반 ESP32 인터페이스 보드 설계

Abstract

This paper explores the design and development of an interface board crafted for seamlessly integrating diverseelectronic components and computers into autonomous mobile robots. The distinct communication protocols amongthese components often result in internal complexity when using a protocol converter. To address this issue, acommunication interface board for the autonomous mobile robot platform was developed in this study, featuring theincorporation of the ESP32 module with built-in Wi-Fi functionality. This interface board comes equipped withcommunication conversion capabilities for various inputs, including analog, digital, SPI, RS485, and I2Ccommunications. Additionally, a DC/DC converter circuit is configured to supply various direct current voltages, suchas 5V and 3.3V. The designed interface board, based on the ESP32, underwent manufacturing, and communicationexperiments were executed with the central processing unit. The experimental results validate smooth datacommunication. These findings suggest that the designed interface board can be effectively applied to autonomousmobile robot systems.
