And since this is the weekend and I had a little bit of tim, here is the first preassembled arm. I am missing glue, so I can't put it together all the way just yet.
Notes:
- make sure that all the servo horns fit before you assemble anything; it's much harder to make parts fit that are already attached
- make sure that the nuts are aligned correctly (if they are a tight fit due to tolerances)
- every leg is different; make sure you sort parts beforehand
- set the servos via software to positions that make sense; there is no way to adjust those horns without disassembling the entire leg
- the cable of the lower leg servo can be routed under the cover of the upper leg; there is a channel for that
- don't use force, use the file to make parts fit; in a second iteration, we should improve some weak spots
- the shoulder joint, although meant well, hangs in the air, not touching the servo; we should come up with a counterpart to make this stable
- Matt
PS: the bad surface on the yellow parts comes from a bad support structure during 3D printing.
