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 educational settings to large factories and assemblers, they are able to perform simple but important actions, e.g., such as

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

As a result, we can see robotic arms of different sizes, all with different “faces”.

Another notable difference is that this technology can be controlled in various ways. It can be quickly adapted to the end goal of a specific project. Whether through voice, mobile phone, or movement and gestures, it has shown a remarkable ability to be more integrated into our daily lives.

How does this robot arm design impact our daily lives?

Currently, this technology has been helping to track radical changes in some people’s lives. There are studies using exoskeleton prototypes. These prototypes can restore movement to users.

These prototypes can decode nerve impulses. The same is true for projects that aim to restore the sense of touch in people with almost non-existent mobility. By combining them with brain sensors, scientists have allowed patients with impaired sensitivity to regain sensations.

In addition, increasingly intelligent designs have been developed for everyday heavy work. There are several projects aimed at optimizing tasks that involve force. This allows operators to move large structures more easily and even reposition them more precisely. This initiative and many others highlight the importance of human-robot collaboration.

Can this be made with an Arduino?

Yes! Although it is impossible to develop a high-tech project yourself, making one with specific structures and programming knowledge is 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.

How did the evolution of robotics start?

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.

Some design concepts

 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.

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.

Simulate all movements of the human arm

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.

How do they start?

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. Typically, one electric motor is needed for each GDL. Therefore, at least seven different motors are needed to create a design as good as ours.
