Sk450 Deadcat quad project

Back in 2014 I got my Sk450. It came in a kit from hobbyking. ARF. With that purchase I ordered the deadcat frame, and a servo gimbal for an action camera and a couple batteries. I bought a used go pro on ebay and mounted it to the top. I didn’t know how to go about controlling the gimbal at first. over the past two years I have tweaked the settings. Added and upgraded, and now I have a really solid flying machine.

When I finally made the dead cat conversion, all of a sudden I was only getting 3 minute flights. i was used to 6-10 minutes. I didn’t know if my motors were wearing out or if something electrical was wrong. the first thing I did was order some large carbon fiber blades on amazon. this solved my problems with lift and flight time. I added a low battery alarm after one flight where I flew till I was out of battery and broke some stuff.

My first fpv flight was around my back yard on a snowy afternoon. The flight was a success but landing in the snow fried my kk2 board and my speed controllers. Parking me for a while, till parts could be ordered.

After this flight I looked into flashing the kk2 board, setting up the gimbal and extending the landing legs so that the gimbal wouldn’t touch the ground. Also when I added the gimbal to the copter I could no longer use the gopro for the fpv feed so I got a on board security camera. one advantage of a camera like this is it does very well in low lighting.

I have been flying when I can, which unfortunately is not as often as I would like. The sk450 dead cat is a great transition from toys to the real deal.

Quad-copters for beginners

I have been brain storming on doing a series on quad-copters (drones)

some of the things i will cover:

what copter to start with:

Syma X1 and the Dromida easy to learn – rugged – cheap

   

Syma  X5SW FPV with camera and wifi

Intermediate – Advanced

fcc registration

how to fly

getting started in fpv

how to track your crashes

Rover with Robotic Arm – 3d printed – Raspberry Pi – Wiimote controlled

I have been working on this project as a way to get my kids thinking about robotics/ programming and 3D printing. plus who doesn’t want a little rover to drive around and pick stuff up from the couch!

Goals of the project:

Wireless rover that can be controlled remotely and eventually off site via web camera.

The robot:

The rover is a print of donboy’s Autonomous-Webserved-Tanktrack-Robot on thingiverse.com

The code:

Coding and set up found in these tutorials on instructables.com

WiiMote Controlled Servos with RaspberryPi by CyprienA

Raspberry Pi and Wiimote controlled Robot Arm by Boardmaster

and Make OWI Robotic Arm self propelled on tracks controlled wirelessly by the Wii controller and Raspberry Pi by Gerald Strope

Assembly:

Step 1 – Printing
the parts were printed in orange and light blue PLA.
Step 2 – Hardware
the servos were old servos that were gathering dust in my fathers basement.
Step 3 – Mounting/Assembly
i did everything i could to avoid screws, most everything was put together using filament rivets

Obstacles:

the brain – deciding how to run and control this rover has taken a decent amount of planning. i started with an arduino nano, but when it came time to control it i struggled to find a ideal/cheap configuration. i came to the realization that a raspberry pi would be a better approach.

Programming – as i am not really a programmer it has been difficult to get things working. i had a basic loop running on the arduino originally but for now once i switched to the pi he has been dead.

I have been working on getting pwm working with the raspberry pi here is my progress as of Febuary 4th 2016

I will continue to update on my progress as things progress.

Soldiered up the power distribution board and speed controllers, motors, and ran the configuration wizard in OpenPilot. now we are ready to mount everything.

Installed the electronics mounted the motors and cc3d flight controller. Just about ready to fly.

the maiden flight was a success! Very peppy.

By request here are some close up pictures of where I stuck everything.

Flying outside.

Please leave your questions or comments via the youtube videos.

here are my pid settings currently. I’m using position 1 and three.

I will be doing another video with some mods and eventually some fpv.

Thanks, Matt Davis
