Robert Downey Jr. (Tony Stark) has become a superhero for a lot of boys, especially for Alex Pring who got a chance to own a bionic arm (produced by Tyler Petresky) of the Iron Man. A video recently published on the Internet shows a moment when Robert opens a Stark Industries box and presents the prosthesis to a little guy who was born with a partially developed limb.
“The designs are considered bionic because they are controlled directly by the child, with the EMG pads providing a direct control and interface for the arms,” is stated on the organization’s Web site. “To make an arm, a child is first measured (size of residual limb, length of limb, etc.) and the current model of the arm is then appropriately scaled,” the organization explains.
“From there, minor tweaks to the design may be necessary to accommodate any features unique to that child’s condition, and then the arm is printed. From there the pieces are assembled and the electronics are wired together and set in place. Finally, the child must be fitted with the arm and an appropriate socket, and the EMG sensors are calibrated before the arm is ready for use.”
