Project 2

Introduction

In Project 2 (i.e. Quadcopter phase 1), we sought to design and build the frame for an autonomous quad copter, while also testing various electronics to be used in Project 3. Furthermore, the assembled copter was tested to determine if the motors and props could lift the weight of the frame.  To build the copter frame, a variety of replaceable parts were designed in SolidWorks and printed using a MakerBot 3D printer with ABS plastic.  We also constructed a Styrofoam shield in order to protect the props in case of a collision during flight.  Finally, motors and other electronics were attached to the copter frame once it was assembled.  In this section we will delve into the design and construction process achieved during Project 2.

Overview

We modeled the copter’s frame in SolidWorks, printed the parts, and then assembled them.  If any of the parts were misaligned or if improvements could be made (such as changes to decrease part vibration) then those parts could be reprinted and the frame could be easily reassembled.

Similarly to Project 1, the electronics were tested independently before being attached and integrated into the copter.  The electronics tested include the four motors and electronic speed controllers (ESCs), as well as the 9 degrees of freedom sensor stick (9DOF);  integration of the sensors and radio onto the copter was not done for Project 2 – it’s a task for Project 3.  Once all four motors were tested, we attached each one to the end of one of the quadcopter’s arms.

By holding the copter down using ropes attached to a large piece of cardboard, we tested that the motors and props could easily lift the weight of the copter frame.  By running the motors at approximately 40% speed, the copter successfully hovered at a low height of 8cm as limited by the rope (see picture above).

  2. hi,
    nice project!
    i am doing a similar project as my final project for my degree in computer science and i have a question, how do you control the motors? do you connect them directly to the arduino our you have a board to control them?
    thanks

  3. Lipo 7.4v 2000mAh Battery
    is this battery rechargeable? If not what are the option?

  4. Hi,

    In this project you used a single Arduino UNO board ?
    I’m asking this because I saw that in the list parts in “REMOTE STATION” you say that is needed a Arduino UNO, and then in “QUADCOPTER” you say again that is needed a Arduino UNO.

    • We used two Arduino Unos. One for the Quadcopter and one for the base station. 🙂

  5. hi
    i try to interface sensor with quardrotor.i will use arduino nano and c++eclipse to programming it .i try to send a sensor signal from arduino to ARdrone.can you guide me how to open a serial port in c++ programming eclipse and recive that data.i m new for these please help me.
