INTRODUCTION A robotic arm is a robotic manipulator, usually programmable, with

similar functions to a human arm. Normally Servo motor is used for

joint rotation but in this project we used simple dc motor for joint

rotation. It has about same number of degree of freedom as in human

arm.

The project will consists of three disciplines; programming, electrical and electronic and fabricating. In

order for a robot or a robotic arm to pick up or move something,

someone has to tell it to perform several actions in a particular order —

from moving the arm, to rotating the “wrist” to opening and closing the

“hand” or “fingers.” .So, we can control each joint through computer

interface using microcontroller ATmega328

TYPES OF ROBOTIC ARMSREVOLUTE COORDINATE ROBOT ARM :- The revolute coordinate

robot arm is very similar to the human arm and it is capable of many of

the same motions as a human arm .

POLAR COORDINATE ROBOT ARM:- The polar coordinate robot

arm is very flexible and can grasp different kinds of objects around the

robot. The robot rotates by a turntable base and the elbow joint is the

second degree of freedom and moves the forearm up and down .

CYLINDRICAL COORDINATE ROBOT ARM:- The cylindrical

coordinate robot arm has the shape of a robotic forklift. The area which

this arm works in is the shape of a thick cylinder.

PROJECT ROBOT ARM

The arm is most similar to the revolute coordinate robot arm. It has

four degrees of freedom and has a gripper as the end effect

manipulator.

TERMS USED IN PROJECT

BASE :- The robotic arm in the picture is a lot of fun to make and use. A linear base articulated robot arm for surgical. The origin of each coordinate system is defined as s position in one of its ancestries.

SHOULDERShoulder is a first junction to joint link of arm. It is mounted on a circular plastic

fiber plate. It can rotate in 360º on its own axis. Typically, the shoulder is

mounted to a stationary base structure rather than to movable body.

ARM:-A robotic arm is a type of mechanical arm, usually

programmable, with similar function to a human arm; the arm

may be the sum total of the mechanism or may be part of more

complex robot.

GRIPPER :-

Gripper defined as, a person or thing that grips, as in a handshake. In strict

definition, which originates from serial robotic manipulators, the end

effectors mean the last link or end of the robot. At this endpoint the tools

are attached.

CONCLUSIONSBefore finishing this final report, we are going to make a conclusion for

this project from three aspects, which are: project conclusion, technical

conclusion and group conclusion. Project conclusion is related to how we

control the progress of the project and what we learn from the project.

Technical conclusion is kind of conclusion related to the knowledge of

science and some technical tips for this project. Group conclusion explains

how we deal with the communication with the group during the project.
