Don’t underestimate the power of your mind: David ‘Hand Solo’ Aguilar
Don’t underestimate the power of your mind: David ‘Hand Solo’ Aguilar

The opinions of the employees of s You are personal.


Santa Claus arrived with a kit LEGO to the house of one David Aguilar Nine years old, the parts were supposed to build a boat, but instead the boy realized he could use that brick create a forearm prosthesis.

David “Hand Solo” Aguilar is a 21 year old man who was born with Poland syndrome, a situation in which his right forearm is missing. “I was very lucky because I have a movement that allows me to operate part of my prosthesis. It is very simple, it is like the one you have on your elbow, but in reality here the phalanges of your hand are that means it’s like my wrist is connected to everything, I call it the Codoñeca, “David says in an interview with in Spanish.

He currently has four prostheses that he designed and developed with pieces of LEGO technology named after the armor of Hombre de Hierro MK-1, 2, 3 and 4.

Although he is a biotechnology student at the International University of Catalonia and continues to build this type of prosthesis, gives lectures and works every day to get a better result with these devices, the young man also has a YouTube channel on which he is better known as “hand” solo “and he loves music.

“I like music production and you can find all the songs I’ve released on my YouTube channel,” he says.

Example of resilience

David explains that he has become a recognized character for what he built, for which he has received a lot of recognition, and a Guinness record for creating LEGO’s first functional arm. He also received the Personal Self-Improvement Award from the Jacqueline Pradere Foundation in 2019.

The Andorra young man says that it was very difficult for his parents because they didn’t know how to act, especially because there are almost no cases like his in his country. David also had many unpleasant experiences with his condition. He gives us 10 keys to inspire us and be resilient:

  1. Don’t be afraid to be yourself. It used to be difficult for me to show my condition (Poland syndrome so that he didn’t develop his chest and right arm), I didn’t like going outside, today I wear my shirt with my sleeves rolled up and hardly use my prosthesis anymore .

  2. That my story became known I realized that I am not the only one in the world with this situation, and that helps me, because there are hardly any cases like mine in Andorra.

  3. I was lucky to be born that way because I can develop like that a lot of skill with the left hand. Thanks to that, I can build these things.

  4. Use what you have on hand. On a Santa Claus, Santa Claus brought me a kit and a wire that served as a ring for my arm. I built my first prosthesis.

  5. If a child is interested in robotics, you should let go of it. If you don’t like it, you probably won’t enjoy making a robot or using the mechanisms I used for my prosthetics.

  6. Always practice. Be creative until you do something that really comes to mind.

  7. Pay attention to your surroundings. The prostheses are named after the Iron Man armor because a boy told me in a lecture at a school that they looked alike and had a name.

  8. Become an example. I saw that there were many, many people who could identify with me, and I learned that I have helped many people’s children fight bullying and overcome the condition they had to live in.

  9. Never stop learning. I don’t know how to modify an electronic chip to respond to stimuli, but I’m sure one of my prostheses could be connected to the brain if they taught me.

  10. The message everyone should hearis that nothing is impossible and if you are convinced that something is impossible, it is indeed a handicap.
