AeroQuad Stuff

So today, while I was taking a nap, a package arrived with the stuff I ordered from AeroQuad for my quadrocopter. I took a bunch of pictures of all the stuff and I'll explain it. I couldn't experiment with it today because it's late and I haven't finished studying for my Spanish test tomorrow. I plan on weighing everything, working on the Arduno, and balancing the propellers later on this week.

So in the picture above, you can see the view of everything that came. Everything is sealed in its original packaging except the accelerometer, gyroscope, and Ardunio. The second picture (to the right), is just the receipt showing everything that was delivered.

The thing I'm most excited about is the Arduino. This will basically be the brain of the quadrocopter, evaluating everything the transmitter sends and determining outputs for each motor. It came in a nice little box with a bunch of stickers and a little booklet that I probably won't read. The Arduino is probably the coolest item I'll ever see with "Made in Italy" written on it.

So this is the cool box the Arduino came in. It's blue... with words on it.

Here's the box opened. The Arduino is in the center, the information booklet is on the left, and most importantly, the stickers are on the right.

This is the Arduino up close. It's sideways. I'm not sure if it being sideways will be a major problem when putting together my quadrotor; let's hope not.

The next most important thing that came was the shield, to the left. It's not very clear because it's in a bag, but basically, you just put it on top of the Arduino. It's specifically designed both for the quadrocopter and the Arduino so you can easily solder the sensors and other things where they belong.

Another unclear picture. These are the stackable female headers. They simply connect the AeroQuad shield to the Arduino.

These are the straight breakout pins. You can break them apart to have any number connected. You solder them to the sensors and to the shield to easily connect the two together.

These are also very important. The gyroscope (top) measures rotational movement on all three planes. This is necessary so the Arduino can tell how much the quadrotor is tilted and adjust for that. The accelerometer (bottom) measures linear movement on all three planes. It can sense the acceleration of the quadrocopter so it can stay in the same general area in the air. Both give six degrees of freedom and are necessary for stable flight.

This is a servo extension cable. I got seven of them. What they do is connect the radio receiver channels, which are connected to the antenna, to the Arduino. Now the Arduino can evaluate the signals transmitted to the quadrocopter.

The last things that came were the propellers. I ordered four extras, just because according to everyone who's worked on these before, the propellers will be the first things to break. Two of the propellers are normal and two are "pusher" propellers, which are basically reversed and meant to be rotated in the other direction. They simply cancel each other out so the quadrocopter doesn't rotate. I also read that propellers are rarely ever balanced when they arrive, so I need to fix that for each one. If a propeller is unbalanced, it stresses one side of the motor more making it less efficient and decreasing its life. You can imagine what a one-bladed propeller would do to a motor. It's the same thing, but with a reduced effect.

So... that's everything. I plan on keeping updates on this project so you can follow it. Thank you for reading my blog... I just noticed how funny 'blog' sounds. I wonder who made that word up. Anyway, I have to get ready for bed and study for Spanish.
