Robotic arm control through mimicking of miniature robotic arm

In the recent technology advancements, employing robots for handling precise operations were seen in abundance like industrial, medical and rescue operations etc. Introducing human interaction with the robotic arm in the real-time scenario opens new doors in innovations and applications of the robotic arms. This paper reports the making and testing of a miniature prototype robotic controller arm using Bluetooth wireless technology which can be used to manually control an actual robotic arm that has 3 degrees of freedom. The main objective is to design and employ a miniature version of robotic arm which can make the main robotic arm imitate as it does when the miniature arm is operated by a human operator. This can be achieved with the help of simple potentiometers at the joints of the miniature arm. The data is exchanged by the miniature robotic arm and the main robotic arm with the help of Bluetooth wireless interface.
