Abstract (English)

With the current advancements in the field of robotics, there remains a challenge in reliably teleoperating robots over long distances. One of the main problems is that wireless communication often becomes unstable during movement or at extended ranges, leading to loss of control. Another issue is the high latency in executing commands, which can reduce responsiveness and hinder real-time operation. Additionally, delays in transmitting camera and sensor feedback can compromise the operator’s situational awareness during remote tasks. To address these problems, the study developed a wireless teleoperation system and communication protocol for a tracked robot using a Jetson Nano-powered Command and Control Unit (CCU), an ESP32 microcontroller, and a PS5 DualSense controller. The system utilizes dual-mode wireless control through both Bluetooth and Wi-Fi, using the MQTT protocol to ensure reliable connectivity, reduce latency, and provide backup communication in case of failure. Unlike traditional systems that depend on a single communication channel, this approach enables a more flexible and responsive interface for real-time control. The system was validated through three main testing objectives; the experimentation confirmed that stable wireless communication was maintained up to a 50-meter range. Further testing for throughput delay showed that command latency remained consistently under one second during operation. Lastly, the system demonstrated that camera and sensor feedback were delivered within five seconds, supporting near real-time awareness. These results highlight the system's capability to address long-range teleoperation challenges and ensure reliable, low-latency control and feedback. In order to secure wireless communication and guarantee data integrity, encryption algorithms can be implemented into the system in future work. By including autonomous operating features, the robot will be able to react securely in the event of signal degradation or connection loss. Furthermore, adding real-time mapping to the Graphical User Interface (GUI) and incorporating environmental sensors like GPS or IMU can improve spatial awareness and aid in decision-making in dynamic settings.
