Shawn & Lara need a Toolbox... Droid?

[kresty]

Really rough video, but we managed to get him to turn a bit:

Since it turned at home on the wood floor, Lara had the idea of getting the wood bits. Unfortunately, it wouldn't really turn the first day out. So I printed larger "road wheels" in the middle (about 5mm diameter bigger) continuing the theory that if we could get the weight off the ends and into the middle, then it might turn.

That seemed to help a ton. Still doesn't turn perfectly all the time. Part of the problem seems to be that the motors on one end cause it to tip that way, so it's on one of the road wheels and the drive wheel instead of just being on the road wheels. The other problem is that the floor isn't perfectly flat. Dips cause more surface area and make it harder to turn. Though the crests between the dips make it turn more easily. One trick was trying to remember where on the floor it turned the easiest.

We also expect that with the body on it, the increased weight made it harder to turn. Hopefully it has most of it's weight now, so that's good.

A bonus of the wood floor is that it provided an obvious boundary to the viewing area, keeping folks from crowding the droids too much. That was nice.
