This is a Horrifyingly Life-Like Robotic Arm Made From LEGOs
Proving that if it cane be done, it can be done with LEGOs, YouTube user sumthinelse5790 presents this amazing robotic arm made entirely from LEGO pieces. Though its strength is limited, it has a full range of motion designed to mimic that of a human being. This emphasis on lifelike motion is important, as its creator designed it as a prosthetic arm — assuredly as an experiment than an exercise in practicality. Though impressive in its own right, the complexity of the LEGO robotic arm is a gentle reminder of how amazing the human body really is.
