Differential Gears for Lego Robot Fred Arrived!

As you can see in the picture above, I finally received my assortment of gears and rods from ebay seller specialty_bricks. Through no fault of his own, it looked like I wasn’t going to receive my gears at all. The seller shipped the gears in a nice polybag envelope with First Class Parcel and Delivery Confirmation with the USPS. Unfortunately, they were confirmed as delivered last Friday, but apparently at someone else’s house. The person who received my package was kind enough to cut through the poly bag to see what was inside before taping it back up and giving back to the postal carrier for delivery at my house. I wish that I knew the kind soul who thought it was okay to open a package addressed to a different address than his or her own, and I think it’s ironic that Delivery Confirmation, which is meant to ensure delivery at the correct address, actually put me in a worse situation as a claimant for lost mail, because as far as the postal service was concerned when I called the local office was that their computer system showed that it was delivered and the postal carrier claimed to have delivered it at the right house. I have had many adventures with lost, misdelivered, and stolen packages, but I don’t think I have ever been in a catch-22 like this one.

In any event, the gears are now safely here, and the one that I needed the most is this one below–a differential gear. Using two of these, I will be able to use two motors to drive and steer the robot with only two wheels.

I probably won’t have the time to work on Fred again until after SFRA. I will post updates as they are available, and if you live around Kent, you’re welcome to stop by and play with Fred soon.
