Robots in Industry

Today most robots are used in manufacturing operations. The applications of robots can be divided into three categories:

- material handling;

- processing operations;

- assembly and inspections.

Material-handling is the transfer of material and loading and unloading of machines. Material-transfer applications require the robot to move materials or work parts from one to another. Many of these tasks are relatively simple: robots pick up parts from one conveyor and place them on another. Other transfer operations are more complex, such as placing parts in an arrangement that can be calculated by the robot. Machine loading and unloading operations utilize a robot to load and unload parts. This requires the robot to be equipped with a gripper that can grasp parts.

In processing operations robot manipulates a tool to perform a process on the work part. Examples of such applications include spot welding, continuous arc welding and spray-painting.

Another area of processing operations where robots are utilized is assembly and inspection. The use of robots in assembly is expected to increase because of the high cost of manual labor. But the design of the product is an important aspect of robotic assembly.

Inspection is another area of factory operations in which the utilization of robots is growing. In a typical inspection job, the robot positions a sensor with respect to the work part and determines whether the part answers the quality specifications. In nearly all industrial robotic applications the robot provides a substitute for human labor.
