Part Two |
The 1999 LEGO RoboGladiators Event at E3
by Dan Danknick
Our face-off style events were scheduled every half an hour. So with only like five minutes to go, Peter gets an idea for a new weapon and starts throwing it together to mount on his robot Mafune. Amazing. | ||
Here Clint holds a part for Rick as some type of spring loaded grappling hook is resurrected from Rick's bag-o-tricks. All of these guys showed up with tool boxes, bins and gear bags full of LEGO parts not to mention pre-built assemblies. (And yes, that's Darth Maul on the business end of the harpoon claw.) To the right is the main weapon on Rick's robot - a 15 lb. hammer! It was made from lead pieces that came in some older LEGO crane kit, which of course these guys all kept the parts for future kinetic energy weapons. It was driven by eight motors and the world's largest LEGO rack-and-pinion system. |

Christian shows off his robot Dreadnaught with 32 motors and a very cool color scheme. I loved it. | ||
Here are some of the internal subassemblies I built for my robot, below. On the left is the smallest LEGO gearmotor driving a high current polarity switch. The RCX receiver controlled two of these red motors to switch the high current drive motors in "tank style" steering. To the right is my voltage converter module that gets around all the safety designed into the conductive bricks by hooking two 9v battery packs in series for 18v. Details on how I built it are here for your enjoyment. |
