Update 3d model, BOM, static analysis, motion analysis, and assembly instructions.

Update the 3d model, assembly instructions, and BOM.

We may want to also add some to the backhoe at FeF.

Right now we've got 1 hole x 4 hole plates. The legs are moving forward and back a bit, outside their intended plane of motion. Replace those plates with 2 hole x 4 hole plates to try to improve the stability of those joints.

Update the 3d model, assembly instructions, and BOM.

Update the 3d model, assembly instructions, and BOM.

In the model, include a note that those should be bolts, not pins, to prevent the plates from spreading apart under weird loads. We saw this problem while testing.

Use the notes from the build to determine what size bolts to use where. Dan has great notes on the base (the part connected to the tractor).

We may want to wait until we make some of the other model updates so we don't waste time putting bolts in the wrong places.

Check with Marcin that we want the docs to use 1/2".

Update 3d model, BOM, static analysis, and assembly instructions.

We tried to use a minimal quick attach mechanism to attach the backhoe 3 to the lifetrac 6, but the connection was way too lose and unsteady. After a slightly jerky motion of the backhoe, the whole thing popped off the quick attach fingers.

There was also a problem where the backhoe may sometime experience forces which push it up, and the way we had the QA mount set up, this would try to force it off the QA fingers.

We wound up not using the QA mount for now and bolting the backhoe to the tractor until we can figure this out.

I don't think the latest design for the boom and stick is in the 3d model.

Update 3d model, BOM, static analysis, and assembly instructions.

Wait until build is done to validate new geometry.
