Support / Re: Rhino 6 Advisory
« Last post by Johannes @ Robots in Architecture on November 23, 2020, 12:06:11 PM »
Hello Victor,

It seems to be working fine for me at the moment, though I haven't thoroughly tested it. In a few months we will probably cease support for Rhino 5 and move to Rhino 6 as a minimum requirement. We won't require Rhino 7 in the foreseeable future.

Best,
Johannes

Hi Johannes

Sorry for my late reply, Friday we needed to do some stuff and I was not able to work on the programming part of the project. Any how here I am and  I will download the file, scan another part and test it.

I believe we can also reduce the mesh when scanning, I will look at our options in order to have a native file from the 3D scanner, any how I will also test the ReduceMesh in Rhino.

I'll start to work in the scans today and get to you, I appreciate your help.

I'll keep you posted.

Kind Regards
Syed

Hello Syed,

That was a bit tricky, the challenge is that when you calculate an angle, you get some value in degrees, let's say 355 degrees and 5 degrees. When the turntable moves from 355 to 5 it will go 350 degrees in negative direction. What you want it to do is to move from 355 to 365, i.e. just 10 degrees.
I made a quick C# script for that, but treat it carefully as I'm pretty sure that there are border-case where it does not work. I only tested that with your current setup.
The rest was pretty straightforward. Just note that there are some positions where the robot runs into A5 limits. Probably some normals of faces are a bit off in the 3D scan, smoothing the scan might help for that.
Also, I would strongly suggest to use ReduceMesh to reduce the complexity of mesh geometry you import into Grasshopper.

Best,
Johannes

Hi Johannes

I've been working in the code and got better results but my toolpath seems to be wrong aligned, I assume that the transformation done ( rotate, orient, rotate) in the code has to be coherent to my turn table and process directions right? how do I evaluate this. I'm trying to understand the whole set of operations.

I put a green rectangle on the part of the code I am talking about, They yellow rectangles represent the code I changed in order to get what seems a better orientation of my whole process. (turntable, piece).

I hope this is a clear explanation.


If not please let me know.

Thanks

Syed

Hi Johannes
I'm still working on the code you sent me trying to understand each part of it, I'm not sure if I understand everything correctly but also I am configuring the tool, the positioner and everything according to our setup.

I attached our old code which has almost everything already configured according to the post you shared here https://forum.robotsinarchitecture.org/index.php/topic,115.0.html , anyway we cant make that one work. I also attached a draft of how we want the process to run. Which is basically leave the positioner first axis always at 90 degrees, then rotate continuously rotate the second axis and let the kuka robot almost all the time at 90 degrees form the surface of the working piece.

Taking a look at the code you sent me I believe that I might have to change the orientation planes according to the object, process direction and robot tool, right? anyway I will dig more into it .

We are completely new to rhino and Grasshopper, so that is why we are taking sometime in not just making it work but actually understanding the workflow, sorry if that is a but annoying. For sure we Will share with you guys the link of the article.

Kind regards

Syed

Hello Syed,

I think the linked code should work well for that, please give it a try and if it doesn't work as expected let me know and I'll look at it in detail, OK?
And it would be great if you could post a link to the article you mentioned once it's online!

Best,
Johannes
