FLL Submarine
Author: Luna Tang
Near the start of the year, in May, I watched a video about someone making a tiny submarine made out of the following parts:
1. Syringe 60 ml
2. Acrylic cylinder
3. SAN plastic sheet
4. Super Glue
5. O-ring cord
6. Neodymium magnets
7. Silicone lubricant
8. Low friction tape
9. Drone Propeller (not lego)
10. Raspberry pi zero 2 W
11. 5V voltage regulator
12. Motor drivers
13. Radio controller
14. Pressure sensor
15. Laser distance sensor
16. Tungsten pellets
17. Lego
18. Battery
After watching the video a few times, I made a google doc listing all the materials and a google slide of the first four steps on how to make the submarine. In the video, it shows the complete submarine. The submarine can go underwater and you control it with the radio controller. In the video, there is a demonstration with a line for how high/low the submarine is supposed to go and another line for how high/low the submarine actually is.
