Minibots
You have available 1E13 atoms for each minibot, you may select each atom by isotope. You must arrange the atoms in three dimensions to provide:
Power receiver.
No power storage is needed.
Communications module providing data exchange over at least 1m at 1Mb/s. This cannot power other minibots.
Computing module, at least 16 bit 16MB 128MHz, no provision needed for software upgrade (these are recycling units).
Independent movement in hops, up to 1E-2m on the surface or limitless in orbit. Latching to a surface might be sensible.
No maintenance access is needed, these are recycling units, the minibot will be dismantled back to atoms at end of life.
Expected lifetime 100d.
The classes of minibot required are refinery minibot, builder minibot, isotope plate minibot
