Development of a bluetooth-enabled Arduino-based robotic system for remote manipulation and navigation

This paper presents the design and implementation of a Bluetooth-enabled, Arduino-based robotic system for remote manipulation and navigation in hazardous environments. The system integrates an Arduino Nano microcontroller, an HC-05 Bluetooth module, and a six-degree-of-freedom robotic arm mounted on a tracked mobile base. Powered by six Tiankongrc servomotors and two NEMA 17 stepper motors, the robot demonstrated efficient terrain navigation and precise object manipulation. Controlled via a custom Android application, the system responded to user commands with an average delay of 0.42s. It achieved a 92% success rate in pick-and-place tasks across varied surfaces. Power was efficiently managed using a 12V Li-ion battery pack with a buck converter, enabling 2.5 hours of continuous operation. The strength of this system lies in its compact design, real-time wireless control, and adaptability to industrial settings. These features make it suitable for deployment in oil fields, chemical plants, and disaster zones, enhancing safety and reducing direct human exposure to toxic or unstable environments.
