Well,
Time to step back.
Errors were made.
I “pinned” the axis in a place that caused no hindrance and designed a few parts. Today I started in on a new assembly, one to verify motion, and found a lot of interference.
To move the interferences, I need to move hardware.
To move the hardware, I may have to remove the raspberry pi.
If I move the raspberry pi, I likely have to remove it.
If I remove it, I will have to change the software…
As I said, UGH.
Update:
Moving serovs around, being more diligent. May work out ok.
Update 8/1/2012
Being more diligent, things looking better, things still awkward. Moving towards shared axis. I.E. I am looking at having two servos push and pull on opposite sides of a gimbal. If they push and pull in equal but opposite directions, one axis stays stable while the other remains stable. add an equal and identical offset to both, and the second axis moves.
Primarily, I am thinking of doing this for the face’s tilt and rotate. If I were to support the face from the back, and not the bottom of the sphere, I would lose a lot of contigulus space, but the axis with then be a little simpler.
