··· littletinyroboticfish with solid-polymer fuel cell
This robot fish is just 10 centimeters in length. It uses an extremely low power means of locomotion and is powered by a solid-polymer fuel cell called a “power tube”. It was developed by the Faculty of Engineering at Osaka City University.
If you have a neodynium magnet inside a coil with about 3,000 turns, and pass a current through the coil, the magnet moves sideways. When we used this effect to drive the robot’s tail, power consumption was just 10 milliwatts.
Your namecheck just earned you a reblog, pardner.
