Hello,

In the Analysis tab of the Settings window you can switch the display to relative values!

General Discussion / maximum value

« Last post by Foster96 on August 16, 2019, 11:18:37 AM »

Hello,

I am new user here and i have to learn one thing that When i try to simulate the robot motion with the KUKA|PRC free version, i like to view how far are the joint's angle from their maximum value.

Thanks for help if someone knows about My KFC Experience.

Regards,
Foster

Hello,

Sorry for the delay. In the eMail you mentioned that you wanted to do this for multiple surfaces, or did I misunderstand the issue?
Attached would be my variant.
If you want to work on multiple geometries, you need to avoid Flatten and take care that the data paths match. That is why there are several Trim Tree or Simplify Tree components.

Hello,

Just in case I would temporarily disable the firewall. But it shouldn't cause the null pointer exception.
The line numbers from your file probably don't match up with mine due to modifications, so I would just place a few breakpoints and step through the program.
Probably culprits are that there is a typo with the tool or base - do they both exist?
Also, start with a simple program with just a few axis movements and see if they work.

Best,
Johannes

Hi Johannes,

I think I was finally able to sort things out, I didn't notice the "Custom Tool: Plane" component automatically turns the tool by B=90 degrees
(it's also clearly explained in the component help window, I just missed it)

if I was a good mathematician I would be able to extrapolate ABC values from the rotation matrix... but I'm not
so the best solution I found is to use your Custom Tool: Plane component together with Putterfish's Rotate Euler component

hopefully this might be of help for other non-mathematicians like me:)

given a tool with correct ABC values, but where XYZ axis need to be rearranged while keeping the very same reference system orientation:



this way the ABC values listed in the tooltip of "Custom Tool: Plane" are recalculated by your component, and can be used to re-define the very same tool with rearranged axis (both in KUKAprc and in the KUKA itself )

Hi Johannes,

Thanks for the tutorial, just wondering how do I setup the UDP program?
I''m connected to the iiwa, ip properly configured
i'm connecting the command to the sunrise communicator (some firewall stuff popped up, I pressed allow), and run the UDP program on the iiwa.
but I'm getting a NullPointerException error on the HMI.

Code: [Select]

Stopping task due to the following error:
java.lang.NullPointerException
 at prc_core.PRC_UDP.dispose(PRC_UDP.java:334)
 at application.PRC_RunUDP.run(PRC_RunUDP.java:83)

Something wen wrong. Killing Threads and comms.

Subsequent error while disposing task:
java.lang.NullPointerException
 at prc_core.PRC_UDP.dispose(PRC_UDP.java:334)
 at application.PRC_RunUDP.dispose(PRC_RunUDP.java:91)

Hello,

I'll have to look into that, unfortunately this week is rather packed and there are many people on holiday. I may have time tomorrow, but cannot promise anything.
If you can send me a simple file that shows your problem (or one with X and one with Z) that would make the troubleshooting easier, in case the issue is not generic, but specific to your usecase.
One more comment regarding XYZABC: There are multiple ways to express the same position. So if the number is not a perfect 90 degree, it doesn't necessarily mean that it's wrong.

Best,
Johannes

General Discussion / Re: Milled Timber Joints

« Last post by Johannes @ Robots in Architecture on August 12, 2019, 07:37:13 AM »

Hello,

There was just a post about this a few minutes ago: https://forum.robotsinarchitecture.org/index.php/topic,1011.msg2838.html#msg2838
And I've attached a simple timber connection below as well.
The strength of Grasshopper is mass customization, so if you do many connections it makes sense to program it. If you have individual pieces that you mill out of big blocks of material, it makes sense to use a CAM software. From KUKA|prc you can e.g. import data from Fusion 360.

Johannes

General Discussion / Milled Timber Joints

« Last post by Stennis999 on August 12, 2019, 06:53:39 AM »

Hello all, I'm new to the forum and i'm wondering if one of you would be able to point me in the right direction.

I'm a 6th year March student from the welsh school of architecture, we have just invested in a KR 600 FORTEC and I would like to use rhino and the Kuka Prc to mill Unique joints in timber. I have looked through the tutorials and have been unable to find one that shows how to mill from a solid block of material. What is the best way to do tellthebell?

Thank you for your help in advance.
