As kids most of us have had our hands on some or the other sort of Lego kits. Although if you haven't been keeping up, Lego kits have come a long way. With the 'Lego Mindstorms' series you can almost build anything out of it, all you need is imagination and the right skill to assemble the parts.
A guy named Max Shepherd uploaded a video on YouTube titled 'Lego Robotic Arm' where he demonstrates his creation of what he calls a 'Lego Prosthetic Arm'. Similar to what the title claims the arm has a striking resemblance to the movements of a human arm. It has 12 degrees of freedom (DOF), just for your information, a normal human arm is said to have 7 DOF. The arms incorporates lego pneumatic cylinders. Although the movements are pretty slow but are fair enough to look human like. It can lift a couple ponds of weight and pour a drink for you.
The thing that sets this robotic human arms different from the others is; anyone can actually build one with the lego parts that have been used. Unfortunately Max Shepherd hasn't reveled a lot of details online except for the video and a little description, but anyways his work is really worth appreciating.
The controls for this arm are pretty rudimentary, this include a cluster of switches and joysticks. A 4-motor air compressor with pressure-regulation also made of Legos, but for the demonstration Max seems to have simply used hand pumps, that's what it says in the description of the video.
