INTRODUCTION Robotic Arm • A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm. The links of such a manipulator are connected by joints allowing either rotational motion or translational displacement. The links of the manipulator can be considered to form a kinematic chain. The terminus of the kinematic chain of the manipulator is called the end effectors and it is analogous to the human hand.

CONCEPT • The robotic arm is an electro-mechanical device deigned to simulate the complex movements of human arm by employing various mechanical and electronic arrangements such as actuators and end effectors.

• The robotic arm is built upon a reprogrammable environment, making it easier to reassign kinematic characteristics of the arm along the 3-dimensional space. • The robotic arm has evolved to substitute human labor, thereby increasing productivity and quality.

CONTROLLING PROGRAM-IDE • The Arduino integrated development environment is a crossplatform application that is written in the programming language Java. It is used to write and upload programs to Arduino board. •

The Arduino IDE employs the program avrdude to convert the executable code into a text file in hexadecimal encoding that is loaded into the Arduino board by a loader program in the board's firmware.

Arduino IDE supplies a software library from the Wiring project, which provides many common input and output procedures. User-written code only requires two basic functions, for starting the sketch and the main program loop, that are compiled and linked with a program stub main() into an executable cyclic executive program with the GNU toolchain, also included with the IDE distribution.

Arduino Program Sketch #include<Servo.h> Servo servox; Servo servoy; Servo servoz; Servo servog; void arm() { servox.write(90); servoy.write(95); servoz.write(40); servog.write(0); delay(1000); }

void setup() { servox.attach(9); servoy.attach(10); servoz.attach(11); servog.attach(6); arm(); } void loop() { servox.write(60); delay(1000); servoy.write(100); delay(1000);

servoz.write(120); delay(1000); servog.write(75); delay(1000); servoz.write(70); delay(1000); servox.write(180); delay(1000); servoz.write(120); delay(1000); servog.write(0); delay(1000); servoz.write(70); delay(1000); }

SCOPE OF ROBOTIC ARM IN INDUSTRIAL AUTOMATION • The robotic arms will be of great use to perform repetitive tasks of picking and placing of small parts in an industrial production line. • Its use can be extended and exploited by few modifications to do difficult and hazardous tasks for industrial applications. • It can be used to do small assembly work effectively due to its great added accuracy for placement of parts, which further extends the scope of our project.
