DIY Lego foosball table advances to Nerd Cup semi-finals (video)
Expert Lego builder Sariel managed to impress us a few months ago with his fully-articulated robotic arm, and he's now back with a particularly well-timed project: a foosball table built entirely out of Lego. While it's not fully automated (and therefore ineligible for the Robo Cup), it does use some WeDo motion sensors to automatically keep track of the score and announce goals on a laptop connected to the table (not to mention on some sliding Lego bricks above each goal), and it even packs a built-in ball return mechanism to help speed up play. Head on past the break to check it out in action.
Lego arm moves slowly, rocks mightily (video)
If you've made a Lego skull you're ultimately going to need some appendages to go with it, and Polish Lego-mistrz Paul (who goes by the handle Sariel) is the man behind this fully-articulated right arm. It uses a combination of electric motors and pneumatic valves that enable it to move... slowly. In a video embedded below that's overflowing with Marilyn Manson angst (turn down those speakers, office-bound readers) you can see it shambling from side to side and rotating at the wrist as the pneumatic fingers are actuated. The range of movement is impressive, but this thing looks about as easy to operate as a dockside crane and seems slightly less precise. Still, it's an impressive feat of plastic engineering; that it was whipped up over a weekend makes it even more so.
