In current times robots are quite simple machines. Some of the modest tasks that our bodies perform such as picking up something, are a tad difficult for robots. This is because the human brain is capable of processing thousands of bits of data in a split second so that the act of picking up something does happen.

Robots, in contrast to humans, are not born but instead built. These machines are made from scratch by industrial robot manufacturers from everyday materials. This is not the case for robots used in cleanroom applications such as space exploration programs. These utilize unique materials such as carbon fiber and titanium.

Conventional robotic arms will be forged using cast iron, aluminum, or steel. Moving robots will be fitted with rubber tires for grip on the floor and silent mobility. Exposed areas of the robot are covered with shields made of neoprene. Controllers, on the other hand, are housed in steel electrical enclosures close to the robots working space. This review will look at how these machines are built.

Procedure for Building


The design phase is where every robot begins. Various factors will have to be put into consideration during this phase: length of reach, speed of operation, the path of travel, human involvement, and hazardous materials involved, among others.

Most manufacturers have a basic design that is a base for all other models that will stem from modifications to the basic design in order to meet the requirements. Robots like any other forged item cannot do something they were not built to do. They are most effective when handled by qualified technicians, and the processes and overall system are well thought out.


Fabrication of the various parts: supports, arms, columns, and the base occur once the design is completed. The base is stout to stop the robot from tipping over. It is forged by welding or casting.

Parts that merge with the rest of the robot are machined with attention to detail to ensure that they are a custom fit. Likewise, the arms are forged to fit perfectly to the end product.


An industrial robot can consist of over 2000 independent fragments that require assembling. Assembly is carried out by a significant number of procured items such as controllers, wiring, bearings, hydraulic cylinders, and electric motors. The base is the foundation of assembly of parts into the robot until its ready for testing.

To kick start the assembly procedure, mobile robots have axles, motors, wheels, and batteries mounted. Standstill robots do not necessitate these parts. The mobile columns are sub forged with their respective drive motors and encased to the base.

Wiring to the controller

As and when the mechanical assembly has been finished, the plumbing and wiring can be completed. All the electrical parts and sensors should have powered wiring and convey information back to the computer. At times the naked space on arms provides for an ideal location to mount controllers.

If a robot is not mobile, the controller should be fixed at a distance and is linked to the robot by a cable. Once assembly is completed the arms are at times encased with shields to shelter them from welding marks, paints and corrosive materials as well


This is carried out at the client’s place. Immobile robots will be fastened to the ground using bolts, whereas mobile robots will have wiring etched into the ground for smooth movement from task to task.

Some designs incorporate video modules. Immobile robots should be secured in a room or fence so that unsuspecting individuals do not come into contact with them and get injured. The manufacturer will then relay maintenance and operation know-how to the client.


To sum it all up, the robot industry is developing very fast, and this is very good for the various sectors utilizing these machines. The building process of robots is quite straight forward as we have seen above. In order to remain atop of the competition, ingenuity is required to build better machines.
