Boy invents himself a prosthetic arm using Legos

About the solution

David was always obsessed with Legos: he built toys and vehicles ever since he was a kid. That led him to develop a prosthetic limb, as he started creating his prosthetic arm when he was nine years old – and he is constantly improving his creation.

"When I move the arm, the hand opens and closes, which allows me to get things. With what was a toy I have managed to get my dream done”, the inventor explained.

It took all these years for David to come up with this device because the Lego bricks available when he started this project weren’t strong enough to withstand the rigors of the inventor’s daily life.

As soon as the pieces were more adequate, David used a Lego helicopter and jet plane kit he created his new arm. The prosthetic arm is equipped with a battery that works a bicep muscle and has fishing line within the arm to allow David to manipulate the limb beyond his body’s capabilities.

David is now working on his second prosthetic Lego arm: MK-II Project.
