A few days ago, I bumped into Mounir Zoorob's OCTO copter project. It is a very impressive flying monster that Mounir designed entirely by himself. It is 1m in diameter and it has a 3 axis camera Gimbal, all designed from scratch. Apparently he has spent over 4 months very hard at work to finish it on time. I must say he did a pretty amazing job. So I invited Mounir on DepotBassam to write a small review of his OCTO copter flying machine, and here is his post:
Before starting, I would like to mention that the materials used are not the best choice. However, since there was nothing available in this part of the world and shipping carbon fiber parts was not possible I had to go with aluminum and Plexi glass instead. (on that subject, review DepotBassam's post on Lebanese electronics shops for more info)
I used 2cm * 2cm * 1 mm aluminum square tubes and the motors are from DIY drones with 35cm wires 2836/9. Each engine has a thrust of 1300g approximately.
I'm using Ardumega from DIY Drones as the main controller with magnetometer + sonar. So far it has proven to be the best thing I have ever bought for this hobby. i enjoyed it so much i bought it as a kit and soldered everything together
I designed and laser cut the case from a 3mm black plexiglass to hold both the Ardumega and the receiver.
As for the motor controllers, I bought 8 25AMP Turnigy ESC's from HobbyKing.
I am currently using 11*4.7 props but will go with the 12 later on down the road. All well balanced
Ardumega will be responsible for the compensation on the roll/pitch axis at the moment. Later on, I will upgrade it to control all three axis.
|This is my camera gimbal. It currently has 2 active axis , but later on I will upgrade it to 3 axis. Currently I'm working on finalizing roll and pitch, but I am still waiting for the right parts to arrive.|
|Wires were also taken into consideration during the design phase :) very neat :)|
|Wires from the ESC's to main power source are all well soldered and added heat shrink.|
Here's the OCTO almost ready for a test flight :)
Here is the OCTO after couple of flights. I modified the design of the Gimbal and I integrated a new landing gear design on it
|Here is a sample picture from the video I'm taking from the OCTO|
Here is the first video from the OCTO, of course it looks better now but this is just a sample.
|For those who love beer, here's one for you :) Note: I got rid of that beard|
