Le Hover

Remote controlled hoverbot for ME 218C

Remember that elementary school birthday game where you would tie a balloon to your ankle and run around trying to stomp on everyone else's balloon while defending yours? Well for ME 218C our task was to play that game but with remote controlled hovercrafts. We also need a them for our hovercraft and controller so my team of Hnin Ookhin, John Schoech, Garrett Hara and I decided to focus our project around the best thing in the world: food. We made our controller a frying pan that moves the hovercraft in the direction you tilt it and deploys the balloon popping mechanism when you flip the egg (wonderfully crafted by Hnin). Through our prototyping and testing we learned that just actuating the propellers wasn't enough to steer so we implemented a system to drop fishing weights coated in hot glue off the sides of the hovercraft. This worked quite well and we ended up with the most maneuverable hovercraft in the class. Completed spring of 2015.









Left weight down. Ready to bank left!

We won this round by popping all of the other bots' balloons before they popped all of the red balloons in the center console

What an amazing looking meal! Although that cup of green tea is giant...

The balloon popping mechanism had to be safe to the touch so we went with a paper clip mounted to a DC motor. Here it is in the retracted position.

The inside of our controller reveals an inertial measurement unit which talks to our TIVA via I2C. The controller then sends commands to our hovercraft via Xbee which is mounted to the chefs hat to improve range.
