Teenager Constructs Prosthetic Arms With Lego!

If you're fortunate enough to have two legs and two arms that function reasonably well, count yourself as a lucky person. Many of us, those with missing limbs, do not have that privilege.

A serious problem if you’re missing a limb is that prosthetic devices are expensive. That’s why anything that can reduce the price is going to be a great invention for an average person.



Alternatives are essential to the traditional materials that make prosthetic limbs. This is to create it much simpler for more people to have access to artificial limbs.


An ingenious student of bioengineering used one of the favorite toys in the world to build a series of prosthetic arms that work.

Ideal Toy


Lego is not' just' a toy, although it is a helpful toy for encouraging children's creativity and design skills. It also has use of the real world.


For instance, those colorful little bricks that so readily snap together were used to construct model cities, whole robots, and even operating vehicles. These little bricks are not for children only.

Genetic disease


David Aguilar was born with a rare genetic condition that left him with a right forearm that was partially formed. But that didn't prevent the curious young David. He created a passion for producing stuff, and he constructed his first robotic arm at just nine years of age.


Developing the design


David comes from Andorra, Spain, and he continued to produce enhanced versions of his first prosthetic arm despite his disability. He does not allow his handicap to interfere with his dreams. "I was nervous about being around other guys as a child ... but that didn't stop me," he said.

Hand Solo

Ten million hits on his YouTube video, David has now gone viral. He posts his colorful robotic arms in his video under the name Hand Solo. Each version is marked with MK and a number, the way David celebrates the Iron Man superhero and his armor suits from MK.


Every version built by David is better than the last, more complex and interesting. And for the young man, they are a technological triumph.

What the future holds Right now, at the University of International de Catalunya in Spain, David is studying bioengineering. He also works on perfecting his prosthetic limb designs and dreams about what life will have in store for him in the future.

David now uses his fourth prosthetic arm from Lego, but he doesn't stop there. He wants people to be more affordable and available to prosthetic limbs. He is also a perfect person to see a successful design as he has lived his entire life with the challenge of getting only one working arm.


He understands what individuals like him are facing in their everyday lives and wants to make life simpler for them.
