Robotic arm control using MQTT protocol

Abstract

The aim of this work is to create a simple system that will serve mainly as a teaching tool for demonstrating communication in a simple IoT system. The proposed system should allow easily add different devices to the system and establish communication between them and create individual communication commands between devices The proposed system uses the MQTT protocol, which is widespread in most IoT systems. This protocol is simple and therefore easy to implement even on microcontrollers that can be connected to the system.
