Lego Robotic Arm

Uploaded by sumthinelse5790 on Feb 5, 2012This is a model prosthetic arm made entirely of Legos.-hand movements and wrist abduction/adduction are Lego pneumatics-wrist pronation/supination, wrist flexion/extension, and elbow flexion/extension are Lego motors (Power Functions)The main purpose of this project was to accurately mimic the full range of motion of a normal human arm and hand. The secondary goal was to maximize speed and power, yet maintain a consistent ratio between the two for demonstration purposes. It is important to note that it was designed as an above elbow prosthesis, and the yellow shoulder is only meant to act as a static model.The amount of weight it can lift is limited to the shape of the object and orientation of the wrist and elbow, but it can't do much with more than a couple pounds.The controller is a rudimentary cluster of switches and joysticks. A 4-motor air compressor with pressure-regulation was made of Legos. LINK: Youtube

Ciudad Nazca - english documentation video

http://ciudadnazca.net/ "Nazca City" is a land art project, the drawing of a true scale map of an imaginary city onto the surface of the Peruvian desert. To do this we built a robot which moves autonomously, plowing the ground to uncover its underlying color. Because of its scale, the map can only be appreciated as a whole from certain a height by means of airplains or satellite imaging.The project is inspired by the gigantic figures drawn onto the desert by the ancient Nazca culture (200 BC - 600 AD), which can still be seen today. It invites to reflect upon the explosive urbanization of the deserts of the Peruvian coast, taking place since the middle of the last century, and its consequences on environmental sustainability and the quality of living.
