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 help in a number of different situations!

Here, we explain a little bit about their various activities, the way they make great contributions to everyday life and how you can make your own robotic arm at home. follow up.

What can robotic arms do?

The closer relationship with technological innovations brings a series of 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 in which they can help us.

From the educational environment to large factories and assemblers, the robot arm design is capable of performing simple but extremely important 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 and with several different “faces” – from the gigantic ones.

Another great difference is that this technology can control in so many ways. It is possible to adapt it to the final objectives of a specific project with ease. Whether by voice, cell phone or even by movements and gestures, the robotic arm demonstrates a great 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 the lives of some people. 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 design develops for routine heavy work. There are a number of 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 it is not possible to develop advanced technical level projects at home, it is still possible to use some specific structures and programming knowledge to make a robotic arm with ease.

On the other hand, if you prefer national options, you can find more affordable robot arm design models in the market. There are a number of options for structures made with MDF that, with the help of an Arduino board, can program and help train a little 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 evolution of robotics start?

Robot Arm Design 2022

The creation of the robot arm design can attribute 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, there are several subjects that can approach. A robot’s intelligence levels, how it perceives the world around it. The extent to which its presence in the physical world is necessary to consider a true robot.

Initially we will understand some concepts of robot arm design

 Robotics addresses the electronics, mechanics and programming necessary to create a robot arm design. By concept 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 certain 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

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

The human arm is really amazing in terms of the movements it is capable of producing. To have an idea an industrial robot almost always has only 3 degrees of freedom.

If you, 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 full capacity of a human arm.

Robot arm design can simulate all human arm movements

The first 3 GDL of the arm are present only in the shoulder, up and down, forward and backward. The movement that produces the rotation of the forearm, bob is demonstrating each of them below.

Note that the ball and socket connection of our shoulder 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 to turn into a back and forth movement and only then move a part of the arm.

Usually an electric motor needs for each GDL that you intend to have. So at least 7 different motors need to build robot arm design as good as ours, for two arms there are already 14 motors.
