EVO. Ⅳ

This is Eric's 4th LEGO prosthetic that he created during pre-quarantine. The hand was fully inspired by the blue 3d printed prosthetic hand, which he implemented many vital components such as the fingers, joints, and wrist movements. Studying the mechanics of the 3d printed hand, he knew the LEGO prosthetic needed to have two main components; the wrist part and the hand part. Given the freedom of having more LEGO Technic pieces, he started building the base by putting together pieces around his left thumb, and slowly worked around it. After that, he made sure to have two rotatable joints to connect the wrist portion of the prosthetic. After a week or so, he has constructed a LEGO version of the 3d prosthetic hand. Although he successfully built it without instructions, the hand struggled to function properly. Learning from his mistakes, Eric knew this was another step towards success.
