Hi Triumph,
You are completly right, I fixed the Component list just wight now.
Thanks for noticing!
Good question!
Currently, the sensors PCB I have are the ones that I made using a CNC, which is not the best replicable option I think.
If you want I can disassembly part of my robot to do a photo, but I don’t know if it will help you. I’m curious about how other Thor Builders did with the position sensors, any of you can share their experience?
I also remember that someone told me that there are commercial sensors (like this one) that could fit inside Thor… I think that the 3D model can be modified easily to hold that sensors instead of the DIY ones. What do you think?Best regards!
A photo of an Assembled ControlPCB?
I attached one to this message 😉
I
have bought most of the electronic components from Aliexpress and
others like fuses from electronic online shops from my country.Hope it helps!
EDIT: I deleted the previous message because I didn’t attach the image 🙁
Welcome to the Thor community!
Yes, as you say it would be nice to have a way to program the motion in a easier way (probably just giving the XYZ cordinates and the rotation matrix elements). If I’m not wrong I think that Danny is developing a visual tool that makes that, but I don’t really know the state of it. Check his hackaday projects 😉
Also, the Inverse Kinematic equations are available and ready to implement in a program. (It is in my buffer of thing to do, but I don’t know when I’ll have the time…)Hope it helps… at least a bit 😛
Hi Antonio, I can send you PCB+Mats for 30€+Shipping or the already assembled and tested PCB for 60€+Shipping.
Note: I’m not a professional solder, it takes me about 2 hours of work and the results are not like wave soldering (industrial).In both cases the mats include:
- PCB
- All male pins
- All female pins
- All resistors
- All leds
- All capacitors
- All terminal blocks
- The diode
- The fuse
And it does not include:
- Arduino Mega
- Drivers
- Wires
- Motors
- Fans
- Sensors
I prefeer the first option, just because I don’t have much spare time but the assembled is offered anyway! 😉
FAQ has been moved to FAQ Wiki Page.
Hi Thomas,
In this right moment I’m not sure if anyone did a software for Thor that could perform a task like that one.
In the other hand, I’m afraid of the accuracy and precision that those pieces could need. In my Thor (which has no feedback sensors) I have at least 0.5 degrees of error in each articulation…
I use to be optimist with Thor, but I think that maybe this kind of task is too much for the current state of Thor.
Anyway, maybe with the feedback sensors and a nice control software it could be done!Hope it helps!
Hi again!
I just did a clearer electronic schematic that you can see here.
The references can be checked in the Component List wiki page.Hope it helps!
Hi Triumph! You can check the KiCad files uploaded to the repository. But you are right, I’ll make and upload a clearer diagram as soon as possible!
Best regards!
Hi Antonio, I have several ControlPCB V1.0 and mats for assembly them.
What are you looking for? Only the PCB? The PCB+Mats or an already assembled PCB? I’m from Spain, and I think that the shipping cost to Italy is about 5€ (not really sure about this).Hi guys!
After several of days thinking about this and evaluating many possibilities, I think I have a conclusion.
I made a wiki inside the GitHub repository, and it can be edit by anyone. I have migrated the “Component list”, “Thor Builders” & “FAQ” info to the wiki.
In this way, everyone can access to the wiki and edit it. Also, there is a register of changes, so it can be restored in case of “vandalism” or something like that.
This wiki is very easy to edit, enter to the wiki clicking in the “wiki” tab in the repository and edit the page you want just clicking in the “edit” button inside that page. Easy.
If you want to create a new page click on “New Page” button. That’s it. The only thing you have to know is the Markdown format, I suggest you to visit this page where it is explained very well.What do you think?
Best regards,
ÁngelNo problem 😉
BTW, I have enhanced the Wiring Diagram of the Control PCB, now is easier to see how the Arduino is connected with the Control PCB 😉
Best regards!
Hi guys! I just finished the wire diagram of the ControlPCB v1.0: https://raw.githubusercontent.com/AngelLM/Thor/developer/electronics/ControlPCB/WireDiagram-v1_0.png
Tell me if you see any error or you have any questions about the connections.
Hope it helps!
