When I opened the project next time, I noticed that the frames cannot be found in the machining settings. It only showed the new-created frame.

Is it a bug or I did something wrong?

If I generate the robot program and copy and paste the code from VSCodium into Ufactory Studio and run it, the program works (gripper opens and closes). Why does it not work when running the program from RoboDK with the Run on Robot selected? This is a major detriment to debugging as I can't use my gripper at all.

Also, and much less important... when I select Send Program to Robot, it does not get put on my robot... where does it go and how do I get it to the robot?

The problem I am having is that no file is created, and I am at a complete loss. I have tried 100+ variants and looked at every doc and example I can find.

Manual program generation and MakeProgram() both work, but I need the stream recorded instead.

ProgramStart returns 0 errors, but no robot program file is generated after RDK.Finish().

I reproduced the same issue with a clean ABB station using ABB_RAPID_IRC5 and separately with FANUC using Fanuc_R30i.

Is there an additional step required when using RUNMODE_MAKE_ROBOTPROG and ProgramStart, , or am I misunderstanding the intended use of this run mode?

First of all thank you so much for the RoboDK software it's the best OLP software I have ever tried !

I am working on a project for bicycle frame welding. I am extracting geometries from Rhino Grasshopper to RoboDK either as targets or as curves. I wanted to use CFP in order to smooth have curves with IJK to permit a 180 deg around the tool but I have some issues using the avoid collision option.

You will find attached the RDK file with the cell.

The first CFP creates very smooth motion without big joint jumps but with a collision on the tool (photo : Collision_welding_torch.png)

The second CFP on the file has the avoid collision tickbox checked but doesnt converge to a solution (stops before the collision).

The third is a manual program I did using joints target from the first CFP program and manually adjusting the orientation of the torch on the last points to avoid collision. (photo : No_Collision_welding_torch.png)

Is there something I have done wrong in the parameters of the curve follow project ? Is there a better way to achieve the result from the 3rd program using CFP ?
Thank you so much

I'm currently working on a JAKA Zu7 robot with an OnRobot RG6 gripper and an OnRobot Eyes camera.

At the moment, I'm controlling the robot movements and the RG6 gripper successfully using Python scripts both in RoboDK and actual. My next goal is to integrate the OnRobot Eyes camera into my Python workflow.

I would like to know:

Is it possible to control the OnRobot Eyes camera directly from a Python script?
Is there a Python API or SDK available for the camera?
How can I trigger an image capture or object detection from Python?
Once an object is detected, how can I retrieve its pick coordinates (X, Y, Z and orientation) so that I can send them to RoboDK and move the robot to pick the object?
Has anyone integrated the OnRobot Eyes camera with RoboDK while controlling everything through Python?

If anyone has experience with this setup or can point me to relevant documentation, example code, or a recommended workflow, I would really appreciate your help.

I know that I can simulate them in RoboDK as normal, but there are a lot of steps in our process that happen between authoring the paths and simulating them later.

When I use the Python API to import the mod files, it pops up a couple dialog boxes that get in the way and require user input. I need to suppress those dialog boxes and work around them somehow. Here are the two dialogs:

Import Summary.png (Size: 10.79 KB / Downloads: 47)
The program seems to import perfectly. However, the API says that the program is not valid. If I double click the program in the tree it will run as expected. If I select the program and press F5 it will update the program and the icon returns to "valid". But if the script tries to use the Update() method on the program it fails.

If you open the station, there is a "Import Robot Program" script that goes through all of these steps. I hope that you see the same results that I see :)

Does anyone have some suggestions of what I should try? Or what I am doing wrong - which is more likely.

Thanks,
Henry

I have noticed that none of the robot models in the RoboDK library match our KR 210 R3100-2 DH parameters.
I have followed the instructions to model it ourself but we cannot find a way to save the robot itself as a .robot to a local library to be used in other stations

Also, It might be better to simplify the robot geometry further to ease the collision checking computation or, as it is done on the Gazebo simulator, add an additional fully simplified mesh just for collision checking

I am attaching my robot station for you to compare

I am using a FANUC CRX-10iA with RoboDK 5.6.7.

I found the existing forum threads explaining that multiple configurations are
not currently supported for FANUC CRX robots.

I would like to know whether there is any alternative way to obtain all valid
inverse-kinematics solutions for a given Cartesian pose.

In my test, SolveIK_All() returns only one solution.

However, I confirmed that another valid joint posture exists for exactly the
same Cartesian pose. I verified this using SolveFK(), and the pose difference
was effectively zero.

I also tried SolveIK() with the other valid joint posture provided as
joints_approx, but RoboDK still returned the same single solution.

Is there any alternative API, solver, robot model setting, or recommended
method to obtain all valid IK solutions for the CRX-10iA?
