The prostheses are adapted to its physical properties: David Aguilar, and his not properly bildtete Hand and pulls a lever to control the gripper. The elbow movement is supported by the Motor that drives normally, the chassis of the Jetmodells. Interestingly, the entire prosthesis was constructed from a single LEGO kit.

In addition to such projects, the music makes Aguilar on a Soundboard and tells his life story in Videos. After graduation, he would like to produce affordable prosthetics for people in need, he reports ABC News. “Because, what is normal?”, he says. His upper limb prostheses from Lego, he uses, meanwhile, only occasionally. They are more of a Symbol of what is possible. Therefore, he puts them in his University.
