Thanks your the best!
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
how to fly
getting started in fpv
how to track your crashes
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 rover is a print of donboy’s Autonomous-Webserved-Tanktrack-Robot on thingiverse.com
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
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
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.
Check out the live stream of the printing here.
Warning! (this is a live stream of my printer it might not always be printing depending on supplies and my time)
Happy new year! I ended the year with the parts for the left arm printed and dry fitted together.
Goals and progress for January:
I have received some old Futaba servos I will be using till I can get some high torque ones to replace, also I got the fishing line for the hands. I ordered cranberry red TPU filament and have decided to reprint the fingers so that they will grab and bend better. initial tests have been successful. I am thinking about printing all of the non structural parts in the TPU.
As of right now I am mounting the servos and reprinting the fingers in TPU, and stringing up the fishing line.
I will continue working on the left side of the robot. Working up from the arm to the bicep, and solder. Maybe February will be the month of the right arm??
Now that I have the left arm mostly complete I have to really dive into my robot lab. I have played around with it but have not been overly successful getting things to work. also i have not yet been successful in installing my robot lab on the raspberry pi, as this is going to be the brain this is an important dilemma. I guess I have to learn something. frown face.
Some other thoughts:
I have learned a little about conductive filaments and got the bug to experiment with integrating it with the inmoov. In the same way Robyn now has touch sensitive arm I could do up some dual extruded conductive arm pieces to create a more integrated touch system. these are just some ideas, first I have to get my printers dual extruder working and order some conductive filament.
Now I finally have that 3d printer, i was bragging to my buddy Jimmy. He seemed jelly and said, “well can you print other things than McDonald toys?” The birth of the project.
I had to find a better project than printing out desk toys so to the www I went. Eventually finding myself looking at the open source inmoov robot project. problem solved!
The next decision was what would he look like? Now im not really a modeler so shape wise it would be the same as the regular inmoov but color, I had some options. pink and purple? rainbow? Sparkle glitter? Umm…
So I went with black and translucent Red. I ordered me some PLA and ABS. (Unintentionally, I originally wanted to do only PLA but my lack of attention landed me with a roll of black ABS.)
Here is what i got:
Black ABS HATCHBOX 1.75mm Black ABS 3D Printer Filament – 1kg Spool (2.2 lbs) – Dimensional Accuracy +/- 0.05mm
Here are some pics of it dry fitted together.
I tried plastic welding the pieces together and ended up messing up the seam. I tried sanding, reheating and acetone, and more sanding. Its looking better but still lacks the luster I would prefer. I’m going to epoxy coat it when I’m ready to gloss the pieces back up.
(Ashton) My 7 year old giving him a high five.
As of right now, I am giving my printer a break to print some Christmas gifts.
I ordered one Arduino nano to control one hand. I have connected the nano to a breadboard to make connections easier. I even got it working a couple RC servos I have.
On my purchase list is hk servos. fishing line for the tenants, screws and other hardware.
I was thinking of getting some TPU for more cosmetic pieces to give my robot a softer more approachable exterior.
I’m looking into running my robot lab on a raspberry pi board to control the robot.
I picked up a pi zero to be the brain. (How cool would it be to say the brain is a $5 computer) … REALLY COOL!
I Just got my borlee dual head 3d printer. This is a walk though of the unboxing, assembly, wiring, setup, and printing.
What it came with:
Package include: 60D 3D Printer+1kg PLA filament+4GB SD Card+a set of Tools+Sample Filament(about 2 meters) to test
It is a full kit and need to assembly by yourself. Don’t worry, we offer a SD card in the package and you can follow the SD card file to install it.

Still need to order:
Low battery alarm
onboard fpv recorder
I received the package fairly quickly everything seems in order.
I got the frame together with little issues. there was a bad thread with one of the aluminum risers. But I made it work.
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.
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
