Quadcopter

Abstract

The Quadcopter is a four rotor remote controlled aircraft. It takes in remote commands from a hobbyest remote control, and achieves steady flight by utilizing a 3 axis accelerometer and a 3 axis gyroscope to determine the current attitude. It then takes the values from the remote control, and current attitude, and determines the needed changes to the motors to achieve the desired flight.

Objectives & Introduction

The objective of this project is to build a remote controlled quadcopter that is capable stable flight. We will control the quadcopter via a Spektrum DX5E hobbyist controller. We will be creating an Inertial Measurement Unit(IMU) using a 3 axis accelerometer and a 3 axis gyroscope. The IMU will communicate with the SJ One Board via I2C. We will be implementing a complementary filter in software to estimate the quadcopter attitude, and will then have a PID control loop in software to generate outputs to the motors.

Parts List & Cost

The table below summarizes the parts used and the cost for the Quadcopter project.

Design & Implementation

Introduction

The motion of an aircraft can be described by three types of motion: Roll, Pitch and Yaw.

Hardware Design

Discuss your hardware design here. Show detailed schematics, and the interface here.

Hardware Interface

In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.

Software Design

Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.

Implementation

This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.

Testing & Technical Challenges

Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.

Include sub-sections that list out a problem and solution, such as:

Wifi Connection Issues

Many wifi connection issues were encountered. To solve this problem, a dedicated task was created to re-connect to wifi if the connection was ever lost.

Conclusion

Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
