eir tasks in a faster way, more efficient and highly better than a man can do in term of precision and endurance. The different between each arms and the functioning role of the arms are depending on the tools that are fixed at the end of the arm, or they call them the end-effectors. Industrial robots can also being classified into [16]:

 

Vertically Articulated

 

The multi-jointed arm of a vertically articulated robot is connected to the base with a twisting joint. The links in the arm are connected by rotary joints. This type is often called jointed-arm. [16]

 

Cartesian Coordinate

 

This robot is limited to x, y, and z movement. It is also called a rectilinear robot. All of the robot arm links are connected with linear joints. The physical appearance is square [16].

 

SCARA

 

The Selective Compliance Assembly Robot Arm is ideal for precision work within one plane. Its work envelope is cylindrical. It has two horizontal joints [16].

 

Cylindrical

 

The robot has one rotary joint at the base and two linear joints to connect the links. Their work envelope is also cylindrical [16].

 

Polar

 

The arm is connected to the base with a twisting joint and a combination of rotary and linear joints. They have a spherical-shaped from outside look [16].

 

Delta

 

This robot configuration combines a rotational joint and parallelograms. Delta robots work within a dome-shaped work envelope [16].

 

Welding arm

 

Welding devices such as MIG-welding gun are one of the popular robot guns that are widely used in the industry to assembly their products. Welding arms are programmed to carry out specific task – welding process repeatedly, fusing of adjacent parts together with uniform quality at a rapid speed.

 

Robot Spray ArmThe next tool will be the Spray Gun. As we know, Spraying evenly on the surface is never an easy job for human. Hence, it is also popular to apply the spray gun into robot arms to do spraying for human. Besides to achieve nearly perfect quality or spraying, they also help to relieve the human from this hazardous and skilful job.
