I decided to do some work on the LEGO MINDSTORMS Space Shuttle. As some of you may know the orbiter’s mass alone is close to 5 kilograms. (Imperial units, that is about 11 pounds!) This puts a huge amount of stress on the gear boxes that drive the motion of both the Canada robotic arm and the rocking of the orbiter itself. Every 3 months or so, I have to take the shuttle apart and inspect or fix the gear boxes. The arm Baz built has been clicking lately, but I have discovered that is just a torque issue (too much in this case). I can fix that in software. The bigger issue is the gear boxes John built. They eat LEGO, literally. Check out the picture of the parts that I removed from the gear boxes. Those are half module bushings that have been eaten away.Yikes!
Also, special thanks to my brother, Anthony. He sent up his nice Nikon camera in preparation for my trip to Australia next month. It takes beautiful pictures!
