| Abstract | ||
| This paper presents an in-depth mechatronics design methodology for developing a wireless master-slave humanoid robot arm, combining mechanical engineering, electrical system design, and advanced programming to deliver a fully functional robotic system. The primary objective of this work is to develop a safe and reliable solution for executing tasks in environments that are too dangerous or inaccessible for humans such as bomb disposal, volcanic area exploration, and contaminated zones. The development process included a detailed mechanical design of a six-degree-of-freedom humanoid arm, as well as the construction of custom printed circuit boards (PCBs) and power systems. The electrical system integrated multiple microcontrollers, rotary encoders, motor drivers, and solid-state relays, all coordinated through custom-developed control architecture. A key feature of the system is the implementation of a robust wireless communication link, based on the nRF24L01 module, providing real-time control and feedback over distances up to 50 meters. The control algorithms allow the slave arm to precisely mimic the movements of the master arm using master-slave synchronization. After extensive testing, the robot demonstrated reliable performance and responsiveness, confirming the practicality and efficiency of the proposed design. This work not only shows the potential of wireless teleoperation in high-risk scenarios but also contributes a scalable design framework for future robotic applications in hazardous environments. | ||
