It was fun taking R2D2 to take your droid to work day but the front foot drive is once again loose. Driving in our parking lot going from one building to another took it's toll on R2. The pavement was rougher than I anticipated. That in addition to the main building he drove was tile and very bumpy tile with large grooves between the tiles. It was akin to taking R2D2 on an automotive test track. I was wincing as the front wheel banged away on the bumps. Many R2's in the club probably couldn't even go on surfaces like this but mine is like a tank. A tank with a delicate front foot.
I must .... must must must build a completely new front ankle / foot design similar to my rear motor mounts. It just makes sense. The stupid pivot point on the ankle is such a waste and completely inefficient for a droid that won't have 3-2-3 configuration. Recently FordFun signed my guestbook with a note that he just completed a design like that. If you're reading this, I would love to see some pictures of your design.
For now I will remove the foot and fix it again as there's another charity event that would like R2D2 there to entertain the guests.
