Jittery finger problem

Up: Finger problems

This page is completing the finger problems pages.
Beyond fat fingers and sticky fingers suggesting themselves are:
sloppy fingers, wobbly fingers, and jittery fingers.

Deflections (wobbling) from thermal motions

The concern here is that nanorobotic machinery and tooltips may jitter too much to allow for positionally atomically precise mechanosynthesis.

This is strongly related to wobbly fingers and sloppy fingers as
stiffness (and choice of robotic geometry) is what keeps deflection amplitudes (jittering)
agitated by thermal motions in check. So the concern is discussed there. Results are promising for this to work.
