Inventor Matthew Perks is back at it again, and this time, he’s successfully built a working submarine with full buoyancy control. Now before you get too excited, this isn’t something a person can dive in, but rather a smaller model that comes equipped with large syringe-like devices in the fore and aft to compress or decompress water.
The 3D-printed actuators double as plungers that travel on a lead screw, while dual high-torque motors and acrylic encased batteries finish off the build. Let’s just say that this isn’t something you want to test at home due to its size, although the water pumps that act as thrusters should be enough to propel it through a small pond or lake.
