Design and fabrication of 3 axis welding robot

Abstract

Robot is a machine that collects the information about the environment using some sensors and makes a decision automatically. People prefer it to use different field, such as industry, some dangerous jobs including radioactive effects. In this point, robots are regarded as a server. They can be managed easily and provides many advantages. A robot arm is known manipulator. It is composed of a set of joints separated in space by the arm links. The joints are where the motion in the arm occurs. In basic, a robot arm Consists of the parts: base, shoulder, wrist and end effector. The base is the basic part over the arm, it may be fix or active. The joint is flexible and joins two separated links. The link is fix and supports the wrist. The last part is an end effector. The end effector is used to hold. Vibration is the physical movement or oscillation of a mechanical part about a reference position. The Static analysis is not difficult to analyses. It is solved by analytical method.
