Week 7 Semester 2

Quad copter circuit system operations.

For this week, I will explain about the circuit system operation for the quad copter. First, from the battery, voltage travel through the electronic speed controller than go to the motor. This is for supply to the motor. For the circuit, from the battery, voltage travel through the voltage regulator that produces 5 volts than go to the sensor (gyroscope), receiver (5DOFIMU) and Micro Controller (Atmega328). From the Micro Controller go to the ESC and motor. 

Week 6 Semester 2

Design the circuit.

In this week, I started to design the circuit. I have a problem to design this circuit. For your information, this quad copter is using arduino programming. Because of this problem, I have made some research about the circuit. I found a source from the forum quad copter in the internet. This forum discuss about the how to make the quad copter for beginner. From the forum, I had an idea to make a circuit and it is my source. Ic that I choose is atmega328.

Week 5 Semester 2

Assemble the project for mechanical part.

In this week, I have to assemble the mechanical part. The frame, landing skid, motor, and propeller are constructing together. Below shown I have been constructed my project for mechanical part.

Week 4 Semester 2

Buy equipment.

For this week, I went to the Jalan Pasar to buy some items needed to complete my project. I bought 4 Electronic Speed Controller (ESC), wire connectors, blades, battery and board. The expenses for this all item are RM1000.

Week 3 Semester 2

Buy equipment.

For the third week, I had to go to the rc shop located at Amcorp Mall and Times Square. There I have made a survey of the equipment needed to complete the project by making a comparison store that offers a more affordable price. I have bought a controller, the frame and the 4 motor. The expenses for this all item are RM1500. The most expensive price is the motor, because it requires more power, torque and durable to lift load 2kg for long time.

Controller and receiver 9 channel

Frame with landing skid and battery holder

Brushless motor 750kv

Week 2 Semester 2

Finalize the equipment.

For the second week in semester 2, I have decided to finalize my equipment that I want to use in this project. The equipments are, Frame, 4 Motors, 4 Electronic Speed Controllers, Controller (Transmitter/Receiver), 4 Propellers, Boards (Power Distribution Board), Wire/ Connector, Battery and Battery Charger. 

Week 1 Semester 2

Introduction

This project is to build a quad-copter that can lift up for about 2kg load and can be controlled by controller wirelessly. This can perform by using more speed and trust of motor to lift the load. For the frame, it must more strength but light. For this quad copter, it requires main circuit, frame, motor, propeller and controller. Below is how the project functions.
