How Robots Work?

Like any other machine, robots, too, have a way of operation. Some are so advanced they will work free from human supervision. On the same note, some are human reliable that they cannot work without people around. All the same, there is a standard way robots work. And that is what this article will explain. From the theoretical underpinning of robot creation to the actual industry application, I will explain the whole idea of robotics. 

Features of a Robot

  • Mechanical

Mechanical features of a robot are those that allow movement and coordination. Varying robots are made of specific parts to facilitate action and movement. This equips the robots with the ability to move. During design, robot manufacturers ensure they have created a robot with the right features to tackle the tasks at hand. This way, they are sure the creations will work properly and deliver the expected results.

Mechanical parts of a robot alone cannot function. But, for remote-controlled or teleoperated robots, they may be enough. That is the reason robot designers bring about other features. Coordination with these additional features allows even autonomous robots to operate independently. This task can sometimes be tiring, but it is always doable.

  • Electrical features

Remember, a robot is a machine. Like any other machine, it needs the power to operate. That is the reason most robots are made electrical. This electrical connection allows the device to be powered and action to take place. With mechanical parts well-built and the robot well-powered, it can work for many hours a day, consistently for years. Still, there is a need for proper maintenance to sustain quality delivery.

Take electrical features out of a robot and get rid of its life. This means, for a robot to operate correctly, you have to power it properly. Just like oxygen is critical to man, so is electricity to a robot. Remember, a robot will work excellently with enough power and lose productivity when there’s no power.

  • Programming

Man has worked so hard to make robots self-controlled. Still, achieving full intelligence like that of a human being with spontaneity has been a significant limitation. That does not man from programming robots. Robots are programmed to do repetitive tasks. This is not as challenging as doing daily decision-making tasks that require proper research and evaluation.

Most robots are made to work in industrial environments with harsh conditions. Besides doing repetitive tasks that can be tiresome, they ensure humans stay aware of such risky environments. Even as they work in these places, a maintenance team stands by to ensure everything is in place. Even with programmed robots, both electrical and mechanical aspects of the robot must be taken care of. That provides all these components work together to ensure the overall objective of the robot is met.


A robot has three major components that come together to make one fully operational robot. The three are electrical, programming, and mechanical. A human being has a body, brain, and interconnected organs to make them alive. Electricity to a robot is equivalent to oxygen to a man. Similarly, a human’s brain is equivalent to the programs fed to a robot. Man has hands, legs, and other body parts to allow for movements and carry out tasks. Likewise, a robot is made of mechanical materials brought together.

Think, for instance, about a robot arm used for fastening screws in a manufacturing site. Well, such work is tiring and requires proper coordination. So, a robot arm will be made mechanically. Once that is done, it will be connected to a system to aid in transferring instructions. This connection will always allow power to make its way to this arm.

With this physical setup ready, instructions and power will flow to the arm simultaneously. With every unfastened screw approaching, the component will be instructed to tighten it. Once the fastening is done, the robot will be prompted to hold on until the next unfastened screw approaches. When it does, the robot will again engage and only stop when the criteria for abandoning the task is met according to the program.

For this coordination to be effective, both components of the robot must be in optimal conditions. The electrical and mechanical parts require the program to be well set for work to take place. Any failure of any of the components may lead to malfunction or total breakdown of the system. That’s the reason the organization’s maintenance team should always be on standby to resolve any mechanical, electrical, or programming issues.


Robots, like any other human creation, have limitations too. One major shortcoming is their inability to think and act by themselves. Some actions require spontaneous reactions and not programming. That may mean no response from these robots, especially in times of emergencies. Besides, robots cannot undertake some tasks.

Some robots also keep working when there is no task to undertake. This may be the case when a reliable human-robot is abandoned. As long as the human is away, it will maintain the status until the operator is back. If the machine is working, it will keep working until the person in charge comes back. If it isn’t working, the robot will only start working until the operator comes back and make it work.

This means that you should be around whenever you control a robot when it’s time to start and stop working. Besides, it would help if you stayed close to ensure nothing went wrong. The fact that robots don’t have the brains to adjust to situations means there can be problems when a situation needs reaction occurs.


Robots rely on programs keyed in them to work. Some depend so much on human control, while others are autonomous and can work independently. Autonomous/ independent robots are the most reliable ones as they can carry out tasks without human intervention. This means human intervention is also a key input in the proper working of a robot.
