Flydo

[O.J.Vodka]

Flydo can extract bottled liquids from the bottle filler and bottled gases from the canister filler. When the power bank of Flydo is about to run out, it will actively search for and install an eco power bank for itself, and discard the previous eco power bank with too low battery. Bionic duplicants will not install eco power banks with too low battery for themselves.

Alternatively, add dedicated charging stations for Flydos. When a Flydo's power bank runs low, it will fly to the charging station, remove the depleted power bank, and install a fully charged one. After the Flydo departs, the charging station will recharge the empty eco power bank. The entire process does not require duplicants' involvement.
