This RC sub has magnetic couplings to transmit torque through the walls. No need to drill holes = no leaks. At the end I test it in a swimming pool. Enjoy!
Differences to the first sub https://www.youtube.com/watch?v=tGEZApd9MMk
rectangular hull (need flat walls for magnetic couplings)
snapandlock lid (more reliable, less leakage)
bigger motors, more motors, more propellers
depth control using propellers (IMO more accurate compared to a syringe ballast tank)
lead pellets for ballast (easier to adjust, both shape and weight, compared to steel plates)
captain (thanks everyone for pointing out this obvious missing part :))
The submarine specs:
Displacement: 2.7 kg (6.0 lb)
Test depth: 1.5 m (4.9 ft)
Hull: glass food container (IKEA 365+ 1.8l), plastic lid
Motors: 3x Lego XLmotor (88821)
Magnetic couplings: K\u0026J Magnetics R844N52 neodymium magnet, TapeCase 4235 UHMW Tape
Propellers: Lego propeller blade (2952), Lego liftarms
Radio control: 27 MHz controller dissembled from a toy submarine (Zantec Mini RC U Boot), L298 Hbridge to drive motors
Power supply: 9V Lego battery box for the motors, 3.7V LiPo for the RC
Onboard camera: Faironly Firefly Q6
Pressure sensor: Jolly Logic Altimeter One

Building a Lego-powered Submarine 2.0 - magnetic couplings

ROV mag coupling test 2.0


Using a brushed 12vdc motor from an 1100 gph bilge pump, some 3D printed parts I designed and some magnets I’m attempting to build a magcoupled thruster. This test uses 1.5\” sched. 40 PVC pipe. Next test is going to be an inwater test of the amount of force it can generate and how much power it draws.
