Robotics has emerged as a more important area in the current technological era. When compared to human labor, robots are more precise. This study presents a method for replicating a human arm by using a smartphone to operate it. A robotic arm is a mechanical device that has been programmed to carry out certain activities. This paper describes the creation of a robotic arm that can pick and place objects and is controlled through Bluetooth. The Android application serves as a transmitter, sending commands to the receiver to control the robotic arm’s movement. The Bluetooth module establishes a connection between the phone and the robotic arm. After linking the robotic arm with the smartphone’s Bluetooth, different moments of the robotic arm may be controlled with a single tap on the android application.
