basically a machine which is very similar to a human hand, it consists of a combination of links attached in series or parallel. It can be controlled by programming it to perform a specific task [3].
prototype of a robotic arm which can be controlled through wireless technology. In this scheme, robotic arm of 4 Degree of Freedom is manufactured and is controlled wirelessly through a mobile app developed using MIT inventor [1] which works on Bluetooth technology. Data from the app is sent serially via Bluetooth transmitter and thereby processed on the receiver which is then used as a reference to control the robotic movement. Successful tests on the linear movement of the robot were performed which results in elevation of robot deployment potentials.

1.INTRODUCTION The development of robotics technology basically aims to assist humans in performing a particular job, and it is a very fast evolving research field today. Some specific kinds of robots that can ease human task are arm robot (manipulator robot). Arm robots are designed to hold, lift, and move objects. Robotic Arm are mainly used due to their ability of higher precisions and accuracy which can result in constancy in greater production quality and less production time.
Fig 1: Arduino Uno layout Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack [4]. Arduino Uno can be powered through a USB connection or by an external power supply, and the power source is selected automatically. It can be operated at a voltage of 7V to 12V.
The Robotic Arm can be controlled wirelessly using the Bluetooth Technology, it is interfaced to the microcontroller using a Bluetooth module known as HC05. An app is developed for the android platform, which communicates serially from the android smartphone to the HC-05 module, which then is processed and executed using microcontroller and the corresponding servos. Basic layout of the robotic arm is inspired by reference [1].

1.1 Background A. Definition: The term robot was first introduced in English in 1921 by a Czechoslovakian playwright named Karel Capek in his play titled R.U.R (Rossum's Universal Robots). Robots in the earlier sense are "forced labour" which means slave labour, but in the modern sense of the word, the robot has undergone extension of meaning [2]. A Robotic arm is
