September inmoov update 2016

It’s now September and time for another inmoov progress update. The transparent red I was using finally came back in stock for a day or so, and I was able to get another roll. That allowed me to print the right arm and the rest of the head parts. I need 2 or three more to print everything in it that I need.

I found a windows 10 tablet from banggood on sale! and got 2 high torque servos to start fitting in. also, I ordered two servo hats for the arduinos from amazon.

I’m hoping that I can find some time to dive into the programming side of this project soon. Having a designated pc should help.

this project is really starting to come together.

August Inmoov update

Im back to printing my Inmoov. I just finished printing all the torso pieces and I am moving on to the shoulders. Also I ordered a 360 Kinect to play with. I’m concidering getting a second printer to try and speed up the printing  process. I downloaded the script repository and have started playing with the script inmoov3-full. I still have a ton to do and learn but it’s coming along.

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.

InMoov – January 2016 Update.

Happy new year! I ended the year with the parts for the left arm printed and dry fitted together.

Goals and progress for January:

Construction:
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.

Printing:
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??

Programming:
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.

InMoov Humanoid Robot – Build Project

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

and translucent red pla HATCHBOX 1.75mm Transparent Red PLA 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.

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!
