Mecanum Wheel Robot Car Using FlySky Transmitter and ESP32-Cam Module for Real Time Video Monitoring Approach

Abstract

Omnidirectional mobile robots have gained increasing attention due to their superior maneuverability in confined and dynamic environments compared to conventional wheeled platforms. This paper presents the design and implementation of a Mecanum Wheel Robot Car capable of true holonomic motion combined with real-time video monitoring. The proposed system employs four Mecanum wheels arranged in a standard diagonal configuration, enabling motion in all directions—forward, backward, sideways, diagonal, and rotation—without altering the robot’s orientation. Wireless control is achieved with a FlySky FS-i6 transmitter and FS-iA6B receiver, providing low-latency, reliable command transmission. An Arduino UNO processes PWM signals from the receiver and applies kinematic mixing equations to independently control four DC motors via L293D motor driver modules. To enhance remote situational awareness, an ESP32-CAM module is integrated to provide real-time video streaming over Wi-Fi through a web-based interface. The system architecture combines motion control, wireless communication, and embedded vision into a unified platform. Experimental evaluation demonstrates smooth omnidirectional movement, accurate response to control inputs, and stable live video transmission with minimal latency under indoor operating conditions. The developed robot offers a cost-effective, modular, and scalable solution suitable for applications such as surveillance, indoor automation, inspection, and educational research. The results confirm the effectiveness of Mecanum wheel-based holonomic motion and highlight the potential for future extensions toward autonomous navigation and intelligent robotic systems.
