Inventor Creates 3D-Printed Robotic Arms for Chil dren Lacking Limbs



Altering Lives, One Limb at a Time

An opportunity assembly on the 2013 Colorado State Science Truthful would change the trail of LaChappelle’s profession. A little bit woman got here as much as him, interested by his invention. She was sporting a prosthetic on her proper arm that was little greater than a claw. He watched how she moved and opened it.

“It was extraordinarily eye-opening for me,” LaChappelle says.

He realized from the woman’s dad and mom that the prosthetic arm price $80,000. Regardless of the steep price ticket, the limb was cumbersome, uncomfortable, and never very helpful. What’s extra, the woman would quickly outgrow the limb and want a brand new one.

“I could not settle for that,” he says, including that he knew he might construct a less expensive and extra user-friendly arm.

“That was the second I devoted my life to creating higher prosthetic expertise,” he says.

In 2014, at age 18, LaChappelle began his personal firm known as Limitless Tomorrow, with monetary backing from life coach Tony Robbins.


Life-Altering Expertise

Within the first few years of the corporate’s existence, LaChappelle needed to work out the expertise wanted to create customized limbs for a fraction of the value of present ones.

The mannequin he ultimately developed lets customers scan their limbs utilizing a 3D scanner of their dwelling, relatively than having to get fitted in particular person. Then the corporate prints, assembles, and checks the limb. Lastly, it is shipped to the consumer. By streamlining the manufacturing course of, LaChappelle introduced the price of his prosthetic limb, known as TrueLimb, right down to $8,000.



His first buyer was a bit of woman named Momo, who was lacking a part of her proper arm and hand. In 2017, they met in Seattle, the place the inventor helped to suit Momo along with her new prosthetic arm.

TrueLimb appears to be like and appears like a human arm, proper right down to the fingernails (which will be polished). It is managed by the consumer’s muscular tissues, identical to an actual limb.

Each time somebody is fitted for a TrueLimb, they undergo a strategy of muscle coaching, the place sensors within the prosthetic’s socket study to detect their muscular tissues.
