Abstract- In the recent technology advancements, robots are employed to carry out the tasks that are monotonous or that are unsafe for human intervention in the field of medicine, industry, rescue operations and so on. Interaction of humans with robotic arm can yield many advancements and innovations. In this paper we have presented a model to control robotic arm with three degrees of freedom through miniature arm using potentiometer. The wiper of the potentiometer is connected to the Arduino Uno Microcontroller which is programmed to take analog readings from potentiometer and transmit them. Movements of the robotic arm are achieved through Stepper-Motor, which is a brushless DC electric motor that divides a full rotation into a number of equal steps. The arm is also equipped with a universal gripper to facilitate the pick and drop facility. The main aim is to design miniature robotic arm which can make the main robotic arm imitate as it does when the miniature arm is operated by a human operator.

I. INTRODUCTION

Nowadays, robots are increasingly being integrated into working tasks to replace humans especially gestures of the operator was created.
The paper 3) studies the to perform a repetitive task. It might be difficult or dangerous for humans to do some specific tasks like picking up explosive chemicals, defusing bombs or in worst case scenario to pick and place the bomb and for repeated pick and place action in industries. Therefore a robot can replace human to do work. A robotic arm is a robot manipulator, usually programmable, with similar functions to a human arm.
Degree-of-freedom is used to describe robotic arms. Robotic arms are usually designed and manufactured based on their purposes. The degree-of-freedom and maximum reachable distances about the X, Y and Z-axis are two important factors that needs to be taken into consideration before and while designing a robotic arm.
