Patrol the pool with this Arduino Nano-powered DIY RC submarine

There’s something inherently intriguing about submarines that doesn’t appear to use to different automobiles. Possibly that displays our pure fears and phobias, or perhaps it’s a results of our curiosity in regards to the mysterious depths. Possibly it’s merely that the majority of us won’t ever get the possibility to experience in a submarine. However you will get a few of the expertise with a mannequin, like 15-year-old Ben Kennedy did with this DIY RC submarine.

It is a remote-controlled submarine constructed solely from scratch and it is extremely spectacular. It’s a 500mm-long vessel loosely modeled after the Soviet (and now Russian) Akula-class submarine. However the resemblance is solely superficial, because the Kennedy’s design is 100% authentic. 

The hull and many of the remainder of the elements have been modeled in Autodesk Fusion 360 after which 3D-printed. An Arduino Nano board receives radio indicators from a Flysky FS-i6X transmitter controller through a Flysky iA10B receiver. The Arduino then controls the varied methods that enable the submarine to maneuver by the water.

4 small aquarium pumps transfer water out and in of the ballast tanks to regulate buoyancy. A single brushless DC motor, which is of course waterproof, gives thrust. Two waterproof MG995 servo motors actuate the rudders for yaw and pitch, that are crucial for diving/surfacing and steering. Many of the hull isn’t watertight, so Kennedy positioned a water-proof plastic bag contained in the hull to guard the Arduino and the lithium battery that gives energy. 

Kennedy examined the sub in his household’s yard pool and it appears to have carried out properly. He posted his design information and code, so anybody can construct their very own RC submarine.
