Who has never felt a little curiosity when imagining what everyday life would be like if they had a robot arm design at home to help with daily tasks? The mechanism can have numerous functions and support in several different situations!

Here, we explain a little about their various activities, how they significantly contribute to everyday life, and how you can make your robotic arm at home. Follow up.

What can robotic arms do?

The closer relationship with technological innovations brings many benefits to our daily lives. In this sense, robotic arms have been gaining more and more space. It is due to the wide range of functions they can help us.

From the educational environment to large factories and assemblers, the robot arm design is capable of performing simple but significant movements, such as

  • Moving objects
  •  writing
  • Manipulating small parts with precision or even making 3D prints, for example.

Therefore, it is common to find robotic arms of all sizes with several different “faces” – from the gigantic ones.

Another significant difference is that this technology can be controlled in many ways. It is possible to quickly adapt it to the final objectives of a specific project. Whether by voice, cell phone, or movements and gestures, the robotic arm demonstrates a remarkable ability to integrate even more into our daily lives.

How does this robot arm design impact our daily lives?

For now, this technology has been helping to trace radical changes in some people’s lives. There are studies with prototypes that originated exoskeletons. These are capable of providing their user with the resumption of movement.

These were capable of decoding nerve impulses. The same goes for projects aimed at rehabilitating the sensation of touch in people whose mobility is almost non-existent. By combining the robotic arm with brain sensors, scientists have already made it possible for a patient with compromised sensitivity to feel again.

In addition, increasingly intelligent robot arm designs have been developed for routine heavy work. There are several projects aimed at optimizing tasks that involve force. This allows the operator to have much easier to move large structures and even more precision to relocate them. This and many other initiatives highlight the importance of working together between man and machine.

Is it possible to make a robotic arm with Arduino?

Yes! Although developing advanced technical-level projects at home is impossible, using specific structures and programming knowledge to make a robotic arm is still possible.

On the other hand, if you prefer national options, you can find more affordable robot arm design models in the market. There are several options for structures made with MDF that, with the help of an Arduino board, can program and help train miniature robotics while you have fun! The models usually combine low cost and great functionality.

So, are you already thinking, what would you use a robotic arm for at home if you had one? Tell us in the comments how he would lend a hand in your everyday life! If you liked this text, enjoy the visit to our blog and also check it out:

How did the evolution of robotics start?

Robot Arm Design 2022

The creation of the robot arm design can be attributed to Isaac Asimov, a science fiction writer who, in his short stories, managed to look decades into the future and imagine scenarios and creations that are just beginning to emerge.

Within this science that was born in the imagination of great men, several subjects can be approached. A robot’s intelligence levels and how it perceives the world around it. The extent to which its presence in the physical world is necessary to consider an actual robot.

Initially, we will understand some concepts of robot arm design

 Robotics addresses the electronics, mechanics, and programming necessary to design a robot arm. By idea, it is an autonomous system that exists in the physical world, with the ability to perceive the world around it and interact with it. To achieve a specific objective.

Both robot vacuum cleaners and expensive and complex industrial robots fall into this definition.

In this post, we will emphasize the mechanical issues of robotics. Actuators and the means used by robots to move through reality and to move it, too.

Robot arm: degrees of freedom

A robot’s tasks are directly linked to its ability to move. In mechanics, Degrees of Freedom (GDL) refers to the set of displacements and rotations a robot arm design or system can perform. For example, the human arm does not count the fingers of the hand. It has 7 degrees of freedom, far more than most robotic arms have or are capable of.

The human arm is unique in terms of the movements it can produce. To have an idea, an industrial robot almost always has only 3 degrees of freedom.

If you, the reader, are looking at your arm right now and wondering how it can be more efficient than a machine. Don’t worry; let’s look at an articulating doll that I named Bob to demonstrate the total capacity of a human arm.

Robot arm design can simulate all human arm movements

The first 3 GDLs of the arm are present only in the shoulder, up and down, forward and backward. The action that produces the rotation of the forearm, Bob de, demonstrates each of them below.

Note that our shoulder’s ball and socket connection makes all these movements possible at once. Reproducing this joint mechanically is already a great challenge, and making it functional using rotors is even greater.

Robot arm: Engines vs. Muscles

Robots use electric motors. These motors develop a rotational movement around an axis. This rotation mechanically converts into a back-and-forth movement and moves only a part of the arm.

Usually, an electric motor is needed for each GDL that you intend to have. So, at least seven different engines are required to build robot arm design as good as ours; there are already 14 motors for two arms.
