Hello,
First things first: If you want to use Asgard with the Flysuper8 board, you have to use the files from the “FlySuper8” branch of the Github repository: https://github.com/AngelLM/Asgard/tree/FlySuper8
I think that will solve the communication problem. I’ll edit the documentation ASAP to clarify that.Regarding the board being too big… Which BaseBoxBody file did you use? Is it possible that you printed the BaseBoxBody.stl and not the mod called BaseBoxBody-FlySuper8Pro.stl (https://github.com/AngelLM/Thor/blob/main/mods/stl/BaseBoxBody-FlySuper8Pro.stl)?
I feel like the latter may be my fault, and I apologize. I may not have made it clear that if you are going to use that board instead of the Control PCB, you have to print that modification instead of the one recommended by default. Sorry again.
Hi Adamson, I’m very sorry I didn’t see your message until now. Sorry for the delay in responding.
From the photo, I can see that the Art2BodyA part is positioned further out than it should be (looking at the photo, the Art2BodyA part should be about 2-3mm further to the right).If you don’t mind, please check the following points:
– Check that the gears on the joint 2 motors mesh perfectly with the gear crown on the Art2BodyA part.
– Check that those same gears are correctly inserted into the motor shaft and that they are not pushing the Art2BodyA part outward.
– Check the length of the smooth rod that acts as the shaft on that side of the joint. If it is longer than it should be, it will push the Art2BodyA part outward.Best regards, and apologies again for the delay in replying.
Hello MrKnight, I apologize for the delay in seeing this message. We have already spoken on Discord and are resolving the issues with the AliExpress links.
In any case, since the question of whether this project is recommended for someone without previous experience in robotics and electronics comes up often, I will respond here as well, in case it helps other users.
It makes a lot of sense to ask it, since embarking on a project like this requires investing a lot of time and some money.
I would say that it depends a little on what you’re looking for. If you’re looking for a precise robotic arm to do ‘real’ tasks, I would say that there are better options if you can invest more money.
In my opinion, this project strikes a balance between ease of construction, a low budget, and decent robot capabilities (and a community that can answer questions).As for whether it is possible to complete the project as a beginner, my answer is that if you are enthusiastic and willing to learn, then yes, without a doubt.
There is documentation on how to carry out the project and we can help you and answer questions, but there will probably be times when you have to learn new things to build the robot and that will depend entirely on you.That said, I will tell you the same thing I tell everyone else. It is a long project to complete, probably taking months. You will learn a lot along the way that will surely be useful for other projects, and the result will certainly not disappoint you. Think it over carefully, and if you are sure, go for it! 🔥
Welcome to the Thor community, Marcelo 😉
I’m so glad you like the project! We’ll be waiting for your updates if you decide to build your own Thor!Best regards!
Hello and welcome to the community 🙂
I’m glad you like the project, I hope that, if you finally decide to build a Thor, you’ll keep us updated on your progress!Best regards!
Hello!
Sorry for the delay in responding. Which version of Asgard are you using? The one from this repository?Did you use the “master” branch or the “FlySuper8” branch?
Best regards!
Hello Hasan!
First of all, thank you very much for your words and sorry for the delay in answering!
Let’s go in parts to try to solve the problems you are experiencing, and for that I need you to give me a little more information:
– For the electronics, are you using ThorPCB and an Arduino Mega?
If yes:
– Have you jumpered the ThorPCB connector that would normally go to pin 41 of the Arduino Mega to pin 7 instead as the diagram in the electronics documentation indicates?
– Have you flashed the GRBL firmware modified to work with Thor?
– Have you configured the $$ parameters as explained in the firmware documentation?On the other hand:
– What do you mean by the temperature detection system?
– What alarm does the application give you when you press the home button?Let’s see if with more information we can solve the problem 😉
The connection of the On/Off button is indicated in the diagrams of the electronics documentation. The other button, serves a little for the function you want to perform, in my case I have it connected to one of the IO pins of the board and I have assigned the Homing command, so when I press it the robot is placed in the Home position.
Sorry for the delay in answering, I have added your robot to the Worldwide section with the number 37! Congratulations and welcome to the Thor family 🙂
Hello finlay!
Welcome to the Thor community!
I love to see new motivated members around here 🙂
About the ROS2 repository, currently the status is functional (not counting the docker part, which I have not yet been able to check if it is still working). At the moment I’m dedicating some time a week to it, let’s see if I can start documenting soon!
Hi Sebastian!
Thank you very much for sharing your work, I’ve been taking a look at it and it’s very interesting! 🙂
I have registered your Thor in the section Worldwide with the 35th record and the first one in Argentina! Also, I have included in the Academic presence section a link to your work, so that people can access it 😉
Congratulations for your work and thanks again for sharing it!—
Hola Sebastián!
Muchas gracias por compartir vuestro trabajo, le he estado echando un vistazo y es muy interesante! 🙂
He dado de alta vuestro Thor en el apartado Worldwide con el registro 35 y el primero de Argentina! Además, he incluido en el apartado Academic presence un link a vuestro trabajo, para que la gente pueda acceder a él 😉
Enhorabuena por vuestro trabajo y de nuevo gracias por compartirlo!Hi!
First of all, sorry for the delay in replying, I’ve been a bit disconnected for a few months and I haven’t seen the message until today.
What you are commenting about using larger motors in joints 2 and 3, may be a bit of a problem. The Art1Body part is designed for 34mm geared motors to fit tight. In fact, the walls are narrower than I would like to allow the motor to fit in that part.
If your geared motors are larger they may not fit in the space where the motors should go.
My recommendation, if you can’t/want to use the recommended motors, is to print the Art1Body part first and test to see if your motors will fit.
In the event that they don’t fit, you would have to redesign the part, enlarging it to make room for the motors. It’s not impossible, but it involves a considerable amount of work, as you would have to redesign some of the other robot parts accordingly.Regarding the firmware configuration, if the motors without the gearbox are 200steps/rev (which is usually standard) and the gearbox is 5:1 you would not have to make any changes to the firmware because the parameters would be the same as with the recommended motors.
Finally, regarding the power supply, I always recommend a 12V and no less than 8A, ideally 10A.
Hope it helps!
Hi!
Sorry for the delay in replying, I’ve been a bit disconnected for a few months.
I have just checked the BOM links and I can assure you that the motors to which these links redirect are the correct ones at this right moment.
It draws my attention the case of geared motors, that apparently the manufacturer has replaced the total torque value given by the set of gearbox and motor by the torque value of the motor without gearbox. However, the gearbox being a 5:1, multiplies approximately by 5 the 25Ncm of the motor without gearbox, obtaining approximately the old 121Ncm.
About what you say about the specification of the supply voltage. Stepper motors generate torque by controlling the current in their coils, not directly with the voltage. Drivers are responsible for regulating this current, using a supply voltage (within their range) to be able to “push” the desired current to the motor. Therefore, the supply voltage is more of a driver specification than an inherent limitation of the motor itself.
Hope it helps!
Hello,
First of all, welcome to the Thor community! Thank you for your interest in the project and for wanting to carry it out for your students 🙂Regarding the modification, I’m sorry I can’t help with this. I currently don’t have the free time to do any particular modifications.
I encourage you to do the modification on your own, after a few minutes you will see that using FreeCAD is quite simple and you will be able to do what you are looking for.
If you are not comfortable with FreeCAD, you can always use the STEP models, import them into Solidworks and modify them from there.Best regards!
For the assembly details you can check this post: http://thor.angel-lm.com/forums/topic/is-that-pcb-true/
About the MPNs, unfortunately I don’t know them, they would have to be the ones to look for them
Best regards!
