- A mini-drone aquarium with robotic fish aims to offer maintenance-free aquariums, replacing real fish with robots controlled by a central system.
- Engineering challenges include charging via a docking station, underwater RF communication using 433 MHz transceivers, and water-tight enclosures with 3D printing and O-ring seals.
- The article mentions the boids algorithm for realistic fish-like motion but notes it wasn't implemented, suggesting potential for autonomous fish with sensors instead of central control.
- Comments discuss ideas like charging via electric currents in water, using non-aqueous substances like mineral oil, and cultural references to Red Dwarf and AquaBots.
