'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

  • THOR+ V2.02 WITH FEEDBACK SENSORS!

    dannyvandenheuvel08/05/2017 at 21:07 11 comments

    Finally! It's here, Thor+ V2.02 with integrated feedback sensors :-)

    STL files all online.
    For users how have printed V2.01 all files marked with a leading underscore are new or changed in V2.02.

    Happy printing!
    Thor+ V2.02 is based from the original idea & design of AngelLM

    The difficult part in assembling the robot parts will be the feedback sensor joints, be carefully how they have to rotate around there axis. I will make a manual later on. All the rest is very clear the same as AngelLM his version.

    dannyvandenheuvel04/30/2017 at 12:54 3 comments

    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!

  • 'ADDING SLIPRING TO THOR+'

    dannyvandenheuvel02/19/2017 at 14:47 1 comment

    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!

  • 'ELECTRONIC SHEET THOR+'

    dannyvandenheuvel02/11/2017 at 16:49 2 comments

    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...

    UPDATE!!!

    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.

    UPDATE LIST

    1x Fan 24V 40x40x10mm
    1x Fan 5V 40x40x10mm
    1x Potentiometer 10 Turns 10Kohm
    1x Opto board (init base) https://reprapworld.com/products/electronics/endstops/opto_endstop/

    5x Makeblock angular sensor V1 http://www.makeblock.com/me-angular-sensor

    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!)

Hi Danny!

Great work! Waiting for the updates on your latest robot.

Can you point me to the STL of a gear used in your gripper for the servo? STL_V2.02.zip doesn't seem to contain it.

Thanks,

Andrew

Dear Danny,

First I would like to thank you for your work. You, Angel and Sapio did a really interesting arm.

I am currently trying to build it and I also saw a few things I would like to slightly modify. It would be nice if you could upload the Freecad files so I can access the sketches.

Thanks in advance for your help!

Hello

Some Rar files are corrupt and I have several error reports.
I managed to download STL_V2.04 files but I need a guide for assembling your improved parts. There are some things I do not understand how to mount like the small conical gear bars on the art56
Do you have a guide or a video?

Thank you

Hi! I'm new to this project so excuse me if I ask any silly questions ;) All files looks bit messy to me so I appreciate if you suggest a full list of required files (latest 2.04 version) to download. For the electronic components everything is clear but can I use MKS gen L 1.0 board instead? Thank you!

  Are you sure? yes | no

dannyvandenheuvel wrote 10/06/2018 at 06:54 point

Hi Taras,
You need at least 6 stepper drivers, so MKS gen board isn't good enough. All STL files has to be print, only a few very small parts you need two of them. I know there isn't a real BOM list at the moment, will try to make some if I got a little spare time.

You can follow sepio's page, his build is based on my version at it has good instructions.
See Ya!

  Are you sure? yes | no

Taras Vakulich wrote 10/06/2018 at 07:12 point

Thank you for the reply, yes I did find Sepio's project and following it. Yes, my MKS board has only 5 ports for stepper drivers. But can I also add an additional driver connected to MKS? Such as ramps, just to extend the existing board. If that works, does it require any changes to the firmware?

Hello,

I've been wondering if you guys did some kind of instruction guide for this project.
We're are currently having some issues with the grbl and gcode. Normally we send some simple coordinates and the serial monitor returns either error 20 or error 2 (both are related to unavailable commands or irregular values). We even tried sending G0 A0 B0 C0 D0 X0 Y0 Z0, but it returned error 20.
Is this because we are not working with the micro end stop connected to the pcb or is this because another issue?

With best regards,
Thalles Machado

drew wrote 11/22/2017 at 17:30 point

Danny, if you're going to modify the BASE.stl file could you add a bit of sideways adjustment to the screw holes that mount the stepper motor? This would allow for setting the engagement of INNER_GEAR.stl to the drive gear. If you're not reworking the base I'll make the changes myself.

Sorry for the delay, I will make a update soon, if you will change it earlier you can do the modification by yourself and put the step file on your page. I will collect everything together for the new release :-)

  Are you sure? yes | no

drew wrote 10/13/2017 at 23:04 point

Danny,  Are you interested in a slightly modified ART1BODY_P2? I added a bit of material back onto the side of the part that had been removed to make sliding in the steppers easier. Since you changed the part so the upper stepper can be installed from the top there's no need for clearance below the upper stepper. I feel this makes for a stronger part. I have an stl and Fusion 360 file if you want it although I'm sure you could make the same change quicker.

  Are you sure? yes | no

dannyvandenheuvel wrote 10/13/2017 at 23:46 point

Hello,

I am looking into building a 6DOF robot, but I am still pretty new to it (bought my 3D printer today). As you seem to be much involved into these 3D printed robots, besides the Thor robot arm you probably already have seen BCN3D's Moveo robotic arm, and its 6DOF remix.(https://www.thingiverse.com/thing:1693444)

Is there a reason why you would recommend to build the Thor robot instead of Moveo?

Anyone having some experience with both designs?

  Are you sure? yes | no

Hi, sorry for the late reaction, to answer your question, I think both robots are almost equal to each other. The community around Thor will be more alive I think.
