a LEGO robotic arm has been created by american student max shepherd. the prosthetic limb and digits have been formed entirely from LEGO and serves as a model to accurately replicate a full range of human-like motion, powered by pneumatics. the LEGO-crafted appendage has been completed on a 1:1 scale with 12 degrees of freedom. a play-block constructed shoulder flows into the upper arm, boasting a skeletal LEGO base to uphold the wires necessary to power the device. the elbow is capable of flexation and extension. the wrist of the piece is formed in such a way that extending and flexing movements are achieved with ease with realistic ulnar and radical deviation as well. the joints found in the LEGO-hand allow for the abduction and adduction of each finger, 3 degrees of rotation in the thumb and the independent control of each finger.

the elbow is able to flex and extend in a remarkably fluid manner.

every digit may be moved independently of each other
