Electric Boat
We made an electrical boat (and yes, we put 18 volts of power inside of a public pool). When we were building this boat one group mate said that a one volt motor should be able to power an 18 inch boat. We went along with it because we thought we had no other choice. She did most of the work saying that she did not need our help. So the rest of the group worked on diagrams. When we went to test the boat it went nowhere because the oars kept bending and the water was too heavy for the motor too move. Also the main wheel was made out of cardboard and that got saturated and disintegrated. At the end of us trying to get the boat to work at the pool, my group said we ran out of time and when we gave our presentation after the weekend we should explain how the boat should theoretically work. That was not good enough for me because it was my last project and I wanted it to work. My group allowed me to take home the boat over the weekend to see if I could make it work. I ended up stripping the entire boat of electronics and mechanics. I was able to borrow a 18 volt motor from the Penguin Empire Robotics Team (San Marin's Robotics Club) and I made a whole new wheel and axle out of metal. In the end I was able to make the boat work and it went 10-ish meters.
