Steampunk anglerfish is a mechanical marvel
Underneath the sea are a wide variety of strange and amazing animals. Perhaps none more so than the anglerfish, with its characteristic light-up lure in front of its face. Club Asimov decided to recreate this fish in a steampunk style, using a linkage system to actuate the tail, and another to open and shut its menacing mouth.
Three stepper motors provide power for the fish’s movements, and two Arduino boards are used for control. Additionally, the fish’s lure illuminate to attract human observers, along with a heart that rhythmically lights up.
You can see this mechanical marvel in action in the first video below, while the second provides background on how it was made.
