# Engineering Micro-Submarines To Replace Fish

**[Hackaday](https://daily.dev/sources/hackaday)** · 2 min read · 1 upvotes · 1 comments

## Summary

A maker project called CPSDrone builds miniature robotic fish for aquariums, solving challenges like underwater RF communication at 433 MHz, waterproof 3D-printed enclosures with O-ring seals, and autonomous charging via a docking station. The robots are centrally controlled rather than fully autonomous. The post also highlights the boids algorithm as a missed opportunity for realistic fish-schooling behavior, noting its simplicity could even eliminate the need for a central controller.
