'Thor' robot with addons and GUI

Thor robot based on the author AngelLM

Similar projects worth following
THOR robotic arm with some extra's :) based from the original design of AngelLM, thanks mate for this nice piece of work!
Trying to do something more... follow me to see the addon's and lots of improvements.

This project is based on the THOR robotic arm project from AngelLM and will be a version with lots of add-ons and especially modified for a wide range of 3D printers with a smaller print area.
Also it is my intention to improve a lot of things to the robot his hardware and software.

I am working on a graphical controller that works on PC,MAC and later on mobile devices.
You will have the possiblity to make al the movements on the controller without the need of the robot.
Ones everything is working on the GUI controller it can be transfered to the robot arduino controller
board, with the press of a button and some digital inputs you can run the sequences you programmed in the GUI controller.
There will be a hand controller to move the robot manually and store the points, afterwards you can send these points to the graphical controller. It will be bi-directional programming.
In a further stage the axis will be recorded into the controler so movements can be simulated be moving the robot by hand and can be replayed afterwards.
It's a lot but this will be my challange in the next comming days...months :-)

Any feedback is welcome!

I will send my regards to AngelLM for the original nice designed robot called 'THOR' , without him I could not started this SUPER project!

Everything stays open source, like everything should be...One for All, All for One
All software programs to build the robot are free to download

    Now loading and saving opportunities. Playing has been more fun now because we can save and load! Yeahhh.

    Now you can play with it! Next will be save and load senarios and connection with real robot arm through ethernet. Try to upload new version in a couple of days :)

    Some progress Thor robot arm embedded, almost running inverse kinematics routine :)

    At this moment I build a recorder into the Thor robot gui controller, following will be save and load recorded movements. Then TCP socket to communicate with the real robot arm! will be continued :) I used a other model to test the routine, it's temporary :). Thanks to Luca Filippini for helping me with the Inverse kinematics scripting!

    Finally get my slipring from ebay! It's going to connect my 6 stepper motors and arduino mini.
    I didn't like the many wires hanging around.

    Making room in the base, I have a motor with position sensor and feedback potentiometer wired, now it's time to add the slipring to it : -)

    Build my slipring into a ring that can be attached on the turning base.

    Attached pcb and connectors on it

    6 steppers and 0V,5V,TX,RX for my arduino mini connectors, just to add all connectors in the controller box, very secure work adding all these small pins.

    My helping tool :-)

    Finnished! every wire has his connection, hoooraaayyy.

    No wire to find! That's what I wanted!

    Up to the next part, see ya!

    I made a complete electronic sheet of my THOR+ robotic arm
    Components used:
    1x Main controller board Ultratronics Pro V1.0 based on arduino due
    6x Polulu stepper driver 8825 cooled max 2A - 24V
    1x Logic shifter 3V3 <> 5V 8 channels
    1x USB Host PCB with flashed software PS4 controller to TTL serial connection
    1x Bluetooth dongle 4.0
    1x Slipring 24 wires max.2A for each wire
    1x Arduino Nano
    1x Neo pixel ring (gripper)
    1x Servo motor (gripper)
    1x Stepper motor (base) 17HS16-2004S1 (2A) 24V
    3x Stepper motor geared 17HS13-0404S-PG5 (400mA) 24V
    3x Stepper motor 17HS13-0404S (400mA) 24V
    2x Fan 24V 40x40x10mm

    It becomes time to assemble it! So next week I'll try to put it all togetter.
    In the meanwhile I'm gone put all drawings and stl files online this weekend.
    And after all these works I finnaly can program back on my GUI controller software :-)
    In the next comming weeks I will have a real moving robotic arm, Yeah...


    Drawing has been changed, I had problems to connect to the mini arduino so had to change the communication to a real serial port. I did move my usb host to I2C.

    The base potentiometer has been moved to another analog point, don't need the extra zero potentiometer anymore.

    Removed the stepdown pcb and feed arduino mini directly with 5V and used a fan at 5V.

    Don't use de extra zero potentiometers at the other axis on arduino mini anymore.


    1x Fan 24V 40x40x10mm
    1x Fan 5V 40x40x10mm
    1x Potentiometer 10 Turns 10Kohm
    1x Opto board (init base)

    5x Makeblock angular sensor V1

    Did some testing to use the SDA SCL at the right side on the unitronics board, a little bit tricky but it works now for 100%.
    Needed pullup resistors 1.5Kohm between SDA,SLC lines to VCC. Edit the 'ps4_i2c.h' source and changed all the words 'Wire' into 'Wire1'. Added Wire1.begin() in setup function.
    Now everything is working like I wanted it! Got a spare serial port for connection on my arduino nano.
    Don't forget to attach the usb host module on TTL/USB module and set 'SERIAL OFF' to avoid latency problems. Read the documentation very carefully from the vendor.

    For all those wanted a seperate controller box, there's room enough for the ultratronics pro V1.0 board, if you want a empty holes box, just ask!

    If you want some dimensions, no problem :-)

    Hope you like it! (for some personal modifications just sent me a comment!)

    To fit the roof of the 3 parted art1top part you have to cute a piece away from the left and right side, I will change it in the drawings so you don't have to wurry of it anymore. For those who have printed it already this is the solutions.

    By making the gape it will fit perfectly.

    Also a little drill out for the ventilation screws (I have to make them a little bit bigger.

    Now it's perfect :-)

Hello:) can I use arduino due + ramps-fd instead of  Ultratronics Pro V1.0 ?

Will it fit in the bottom of the arm ?

  Are you sure? yes | no

dannyvandenheuvel wrote 05/18/2017 at 19:19 point

Hi Rurikovich,

You can, but you lose some extra's like ethernet, SD card. It all depends what you want to reach. If you want to connect with the graphical interface you need ethernet and SD card. If you make your own controller or someone else you don't. It's up to you :-) Will it fit in the bottom, no way, to near inside of the base. You could use the addon case, there is plenty of room in it. If you want some modified piece you can ask, if I have the time I will do the modifications for you.

  Are you sure? yes | no

  Are you sure? yes | no

dannyvandenheuvel wrote 05/10/2017 at 15:26 point

Hi Alessandro,
I know the board isn't cheap but everything except the drivers are on this board. If you take a arduino mega with ethernet shield and a driver shield you will pay allmost the same prize. The ethernet will be needed when you want to command it with my graphical Thor GUI controller in the near future. You need 7 additional stepper drivers.
You find the drivers at Pololu site. and the main board at

The PCB has a compatible arduino DUE on board and has the advantage that it is 3 times faster than arduino Mega board.
It has a lot of extra's on board ! I've added a bluetooth host to command it with a PS4 controller for manual movements.

Hopefully you understand why I chose this solution.

  Are you sure? yes | no

dannyvandenheuvel wrote 05/10/2017 at 16:19 point

This is the latest electronic sheet from my project.
There are some addons around the main board but not needed, all depends what you wanted to achieve.
There will be a more detailed drawing comming soon.

Olaf Baeyens wrote 05/10/2017 at 18:51 point

Hello Guiucci, I want to point out that this Ultratronics board v1.0 is an Arduino Due. which operate at 3.3V.  Be careful when you want to hook up 5V sensors, you need a way to convert it to 3.3V

The other thing you must know is that this board can handle 12V or 24V. IF you choose to connect 24V to it then realize that every 12V mark on that board is actually 24V. So you must use 24V fans instead.

dannyvandenheuvel wrote 04/11/2017 at 13:17 point

People are asking me a lot of questions how to build my version of Thor and the electronic parts.

For the moment there are 2 versions I have made upon the original Thor robot from AngelLM.

Version V2.01 has all the 3D printed parts without angle feedback sensors buildin.

Version V2.02 has all the 3D printed parts with angle feedback sensors buildin, these files are not ready online. I'm testing this pieces and at the end of this week they will be public.

The software has a total makeover and I try to finishing it in the next comming weeks.

The basic software can move the robot manualy into all directions with or without a PS3/PS4 controller. It's open source so you can decide to make your own controller or the one I have developed. This project hasn't finished yet, it's still in development! but you can start printing if you wish, if you want angle feedback, just wait for a few days when version V2.02 has been uploaded to my page. You can find all the electronic parts at one of my pages, look for electronic sheet! . There's also a video in the making how to assemble everything and how to build the electronics.

Building the robot is near the same as the original from AngelLM, except a few modified pieces.
If you want angle feedback and did not started printing V2.01 wait until V2.02 has been uploaded, for the people that have printed V2.01 you will see that in version V2.02 some parts have to be re-printed again, sorry for that but like a said, it is still in development.
Version V2.02 will be having all the electronics that I wanted so far, electronics software will be arriving very soon to the public.

  Are you sure? yes | no

Towi wrote 05/02/2017 at 14:39 point

Hey Danny.

Thanks for all your hard work you are doing and the time spent/you are spending.

Since a while I am printing V2.01 parts.

When you release V2.02 would it be possible for you to provide a list containing all parts that would need to be re-printed? Would be awesome.

I am totally new at this (robots) and the only thing I am doing so far is printing, printing, printing.

I am wondering if I can make this actually work.

When do you think the assembly video will be available?

  Are you sure? yes | no

dannyvandenheuvel wrote 05/02/2017 at 15:21 point

Hay Towi,

Version 2.02 will only have effect on the feedback at all axis, I printed them all (about 2 days printing, I know printing is very slow :-( . I used one spool (1kg) on printing the new pieces) . I hope to release it next week. (will have a upgrade list)
For the video, I have to disassemble my robot because I wanted to make the video from the beginning to the end. After that video there will be one for the electronics. I have to do it in spare time and sometimes it's very frustrating to have less time after a heavy bussiness day :-( . I try to do my best to finnish the robot asap. I'm also working on the graphical GUI controller, this will be part of this project and will have a big impact. This will be the big difference between all the robot projects on the web.

I wish you good luck in printing all the parts, be very patient and hope that every
part will be successively printed! I use a very proffesional printer because I use it for bussiness to. Some hobby printers have troubles with overhangs etc... . All my parts are perfectly printed. :-)

See ya!

Did some testing to use the SDA SCL at the right side on the unitronics board, a little bit tricky but it works now for 100%.
pullup resistors 1.5Kohm between SDA,SLC lines to VCC. Edit the
'ps4_i2c.h' source and changed all the words 'Wire' into 'Wire1'. Added
Wire1.begin() in setup function.
Now everything is working like I wanted it! Got a spare serial port for connection on my arduino nano.

Hi Wilmer,

Art1Body was a hard piece to print in one run, that's the reason I splited it into 3 parts, Part 3 is the roof and it will be attached on Part 2 with self-tapping screws. It's also a better solution bringing in the 3th motor from above.

I will be uploading the compleet source in the next comming weeks, The main reason, I don't work in freecad, I exported the origenal files from AngelM to step files and imported it into Spaceclaim, this is what I use in my bussiness days, It will be ported back to freecad so that it will become the sources back into freecad. Spaceclaim can be downloaded as Designspark Mecanical, the free version of this powerfull software package.  Take a look at it! Try it yourself.

Hi Danny.

First let me thank YOU and AngleLM for all your hard work. Looks pretty amazing.

AngelLM's original Thor is suppose to cost about 350 Euros. With all your add-ons do you know what the improved Thor cost?

I haven't looked through all posts and stuff but do you have all files listed to make this robot or do I have to look through yours and AngelLM's files?

Every 3D STL part of the robot arm has been online, take V2.01 if your starting it from the beginning. You can make a choice what kind of controller you want to use, you've got a controller box or a connector box when you are planning to build your controller outside of the robot. I've made a seperate controller box for the one that will make a seperate electronic controller.
I'm just working on the feedback sensors, this will be in the next release be added, I'll try to build it as a addon upon the allready made 3D parts.

Hi Danny, I'm playing around with the Linux-compiled GUI, and it's pretty good so far. One thing I would add in though for us that dislike sliders and want faster accuracy, would be to allow typing in the degrees for each axis instead on sliding a slider bar around.

Hello Martin,

The motors needed to be working at 12-24V (there are a lot of motors with different power solutions, if you order from somewhere else keep in mind to get the right power connection supply!)
I've ordered mine from stepperonline. Good service, good quality! Be aware of import costs involved by ordering out of the europian union. I had to pay a extra 17% at the total amount to dhl.

All specs can be found at these links.

Hi Danny!! Thank you very much for this greats instructions. I started building the robot arm and I was having some problems with the assembly and the electronics.  Your pictures looks amazing and are helping me to go forwards with the assembly.  I printed all the parts at school using five Ultimakers that we have at school. I started  doing Angels versions because I didn´t know about your project.

Hi, nice to see another Thor robot builder :-) My version has been build upon Angels version with some addons and some improvements, the electronics is very different. I'm also writing a software GUI controller on pc win/mac/linux to what the words stand for 'control and simulate' it. I'm not finnished at he moment, you can extend yours with all the tools I'm adding to it. If you have any ideas to improve or extend the project, give me a sign! See ya...

Hello Danny, if you ever get bored and does not know what to create next. One thing that would be nice is a holder to put the Ultrasonics v1.0 board in but in an upwards position with no UI displace sticking out. It would be nice if the robot could rotate 360 degrees without obstacles.

The design I am developing probably will not have an UI near the robot. But I may need a reset button to press as an emergency reset and maybe a LED to indicate the robot is operational.

I am toying with wireless communication, so the UI may be off the robot. 

I volunteer as guinea pig to 3D print it, so you don't have to :-)

Hay Olaf,

I will see if I can make the time for it, it would be a nice extra add-on, and that's what I deliver to the project ... add-ons :-)

I love your add-ons :-) 

But take your time, tthe robot is not yet going to run away here :-)

They asked me to split ART1BODY, I have gone a little bit further,
made 3 pieces of it with a roof that can be opened, you can bring the
middle motor into it on the other way, the structure has been a lot
stronger that way.The two other parts can be screwed togetter and be
glued. I think it will reduce a lot of time printing it and little
structures to use.
Also a fan has been forseen and the roof has some ventilation holes.

Hope you like it!

Made ARTTOP_01 into two parts for all the people how struggle with supports. This solution will definitely help you out. After print them without supports you can glue then together, it will be strong because the screws goes to both parts!
You can download them from my page!

Olaf Baeyens wrote 01/12/2017 at 18:26 point

Downloaded. :-)
I will see if I can test it this weekend.

The original one had a 8.5 hour print job (0.3 mm layers). These 2 will take both each 3.5 hours. It shaves off 1.5 printing.

Hey Danny! Thanks for your work there :)
I have a question, what's the point of adding the cylinder at the top of the piece? I guess that can it could be used for house the screw heads or maybe for structural purpose but I'm not sure.

dannyvandenheuvel wrote 01/14/2017 at 18:07 point

Because the upper half was 2.5mm tick and the screws! So stability and screws sinked into the material. :-) Maybe a little bit of overkill, but I don't want to losen anything of the original strength.

That makes sense. Thanks for the explanation ;)

Hi great mod! Will you be posting this on GitHub? I want to print your model, but not sure where to get all the parts like screws and bars. Also, where did you get your LCD screen? 

  Are you sure? yes | no

dannyvandenheuvel wrote 01/03/2017 at 22:18 point

Hi, Everything will be posted on github by the end of this week, I'm just modifying some small parts of the robot. All electronic parts are from except the display, this comes from nextion All motor parts come from, all other parts can be find by local dealers, most of them are 3D printer parts. I will add a full list of parts. I'm still in development with the electronics and the pc software GUI, so you will have to be patient before erverything has been finnished. 

  Are you sure? yes | no

brett.schenck wrote 01/04/2017 at 11:36 point

That's awesome! I love the the EEPROM Nextion display. It seems easy and fast to make GUIs with. I can't wait to start printing your mod this weekend. Keep up the awesome work!

It took me a longer while to finish everything, I'm almost done, the first part (base) of thor+ version 1.0 has been placed on this project place. The next comming days I'll try to upload every other part of the robot.

I have a complete positioning system that works,
this function I added to the stepper library and saved it to a new
library, you just have to give a position in degrees and it runs to that
point. I added a lot of things like positioning to homing sensor,
emergency stop, stop with or without holding the motor on current,
speed. It's working fine! To stay in sync and let all the motors having
the same speed when one or more motors stop I virtual keep the same time
needed to move the motor 1 step to behold the same timing if it is
running or not. I will mean, by saying it runs to that point, it moves 1
step and gets out of the routine, the next time if it isn't at position
it moves again 1 step so that there will be free idle time to do the
rest of the program. If you don't do it that way you've got different
speeds while moving more than one motor. I'm finalising this routine, it
is working, just the motors are a little bit noisy because I had to put
them on halfstep to have the fastest speed possible. I put a snippet on
my page or you can download the library.
