The robotic arm with artificial muscles capable of lifting a weight of 7 kg

Imagine that one day you are sitting at home and the next few days, you have a roommate. robot humanoid at his side that he has created. Well, the Polish engineer Koźlik łukasz was able to make this a reality: his goal was to create the most advanced human robot in the world, and it seems that so far it has been going great.

The channel Automaton Robotics from Youtube that collects this project has surprised with the following video: one where you can see the arm of this robot, lifting a 7 kilogram dumbbell.

“We have achieved a strong, fast, energy-dense, high-efficiency, biomimetic, soft, safe, clean, organic and affordable robotic technology,” is the description offered by Koźlik in the video description and adds “The dumbbell weighs 7 kg, the forearm with the hand only 1 kg.” How have you achieved this? The secret lies in components called McKibben muscles.

This technology used Koźlik łukasz for his robot

M-RelatedNneumatic Artificial Muscles (PMA) They are devices contracted or enlarged by air pressure with a pneumatic bladder to perform movements. Because they share some characteristics with human muscles, they have been presented as the ideal piece to add to the project.

However, Koźlik has a more secret secret: instead of working with air pressure, They do it with water and electricity. “We are inventing and producing portable power supplies and our own valves,” explained the Pole.

This allows them “completely control the contraction of the speed and compress the entire electrical system (for a complete body) inside the body of a robot“. And, in addition, they provide greater autonomy.

In addition to gaining strength, robots also make a number of completely natural movements: you can see that he moves his finger and makes different gestures with his thumb.

all of it considering that he is currently operating with “half as many artificial muscles compared to a human body”. The objective of this engineer is to provide a sensor system that allows the arm to detect and realize that the weight is the one it is holding at the moment.

As it mentioned above, Koźlik wants to create a strong and agile humanoid robot, but also cheap. “Our goal is to make a universal robot with infinite possibilities. We want him to cook, clean and do whatever job he is told to do.”details in the description of his ambitious plan.

The robot that can hug humans ‘feeling’ affection

German engineers from the Max Plank Institute, they developed a robotic torso that is learning to hugr. It is part of a multi-year investigation that little by little brings new interactions of the machine, such as the possibility of bumping the palm of the hand.

And why is it important to train a robot to perform these gestures so common in humans? Because machines can help humans in everyday life or in various therapies, managing to ‘feel’ something similar to what people feel.

Thus, the researcher, Katherine Kuchenbecker and her team, are developing the technology so that HuggieBot can learn to hug. This robot from the department of Haptic Intelligence at the Max Planck Institute for Intelligent Systems in Stuttgart has the hugging routine.

Teaching machines to feel (translating the sense of touch into technology) is not easy. The main objective of the research is to understand haptic (touch) interactions and improve human-machine interaction.

To create HuggieBot, the researchers studied what physical characteristics a robot should have in order for people to feel comfortable and interact with it. They found that it should be soft, warm and about the size of a human. In addition, he could “look” or make eye contact with the human and also adapt his hug to the height and posture of the person. Finally, the robot must have some empathy and realize when the hug should end.
