Application refers to the type of work that the robot is designed to do. Models for small industrial robots are created with specific processes or applications in mind. There are also different requirements for different applications. For example, painting robots will require small payloads but large movement range, they also need to be explosion proof. On the other hand, assembly robots require small working spaces but need to be fast and precise.
A small industrial robot has software and accessory packages, a specific type of movement, control law and linkage dimension depending on the target application. Here are some different types of applications:
Painting robot
Assembly robot
Welding robots
Palletizing robot
Material handling robots
