Hi all,
If your bot can take the heat, a container filled with boiling water, sealed
and cooled would be completely sterile and last for years and years. Just
like Grandma's canned peaches. This might work if the bot will survive it or
it can be done with less temperature.

See ya,
Jim

Has anyone tried or investigated the use if those moving armature less motors ,
ie ones like they use as heart pumps
these are an archimedes screw in a tube the screw blades have the magnets
embeded in them and all the electric workings are on the outside, to step the
coils on and off
I may be remembering incorectly but I believe the thing was bearing less.
with a motor of this kind damp and corrosion would not come in to the ballgame

I've thought of this too. But, the way power filter pumps work made me think
of it. The only problem I see is that it would have to be made from scratch
(which is usually unreliable) or, it would have to be hunted down like the
infamous BG Micros. That is, rare as hens teeth.

See ya,
