A motorized LEGO® prosthetic arm
After that first attempt, David worked hard to better his existing MK-1 model.
Most people couldn’t believe a prosthetic arm could be made of LEGO®, but David proved all of them wrong and keeps doing so.
His most upgraded and latest MK-V LEGO® prosthetic arm is motorized, with five fingers that he controls through subtle movements of his residual arm.
This specific model is remarkably more comfortable than the previous versions and holds a Spike Prime Hub – a programmable control unit capable of receiving and sending orders from sensors to motors.
Therefore, it’s much easier and less tiresome to use since it doesn’t rely on David’s muscles to work.
"It's the most comfortable prosthetic of my models and I don't need to use my muscles to lift something. The servo motors do it for me!"
The main challenge David faces when building prosthetic arms is balancing functionality and comfort.
"You can't wear something very uncomfortable, even if it's super functional, and vice-versa."
From Han Solo to Tony Stark, David took continuous inspiration from the pop culture around him.
A love for comics and classics reached its peak when, during an event at NASA, he was defined as "the real-life Tony Stark" by Charlie Wen, co-founder of Marvel's Visual Development department alongside Ryan Meinerding.
