Is it possible to change the light rendering settings ?
I have a setup that is hard to display because of the light shading in the application.

I would like to turn off or tune the light settings so the part faces are more visibles.
Do you know how i could do it ?

Thank you.

We are going to run a milling program on an old Fanuc controller. The program will have to be split into smaller pieces in order to fit into the controller. I know that RoboDk can do this splitting - we have done it on previous projects.

Here is the twist... I need to split the program during a retraction so that the cutter does not sit on the material and leave a mark. My first plan (which is my only plan) is to insert some special comment instructions where I want to split the program and then have Python go through and chop it up. Probably making a copy of the initial program, deleting the extra movement instructions, then repeating for how many pieces it needs.

Have you had to do this before? Is there an easier way? I have a habit of just doing everything with Python, but if there is a better way I would certainly give it a try.

Thank you for your suggestions.]]>

I hope this message finds you well.
My name is Naoki Nakajima from Uchihama Kasei Co., Ltd.

We are currently experiencing an issue when transferring a program created with RoboDK to a FAIRINO collaborative robot. Although the program data was transferred successfully, we are unable to run the program properly on the actual robot.

We have already tried restarting the FAIRINO robot and converting the program into Lua format again several times; however, these steps did not resolve the issue.

To help you investigate, we have attached the program data used during the actual data transfer. We would appreciate it if you could review it and let us know your feedback.

Thank you very much for your support.

Kind regards,
Naoki Nakajima

I've been thinking about how differently people approach the physical prototyping side before deploying a robot cell, and I'm curious what the community is actually using.

RoboDK handles the simulation side brilliantly, but once you're ready to test I/O signals, sensor triggers, or controller logic on real hardware, the choice of components can make a big difference in how quickly you iterate.

A few questions to get discussion going:

1. What microcontroller/SBC do you use for testing signal logic before wiring to the actual robot controller?

Arduino? Raspberry Pi? Something industrial like a CLICK PLC? Each has tradeoffs in cost, GPIO availability, and how easily it maps to the real controller environment.

2. How do you handle sensor validation?

Do you test proximity sensors, encoders, or vision triggers on a benchtop first, or go straight to the simulation + real robot combo?

3. Any tips for bridging the gap between RoboDK's simulated I/O and physical test rigs?

I've seen some clever setups using Python API calls to trigger GPIO on a Pi in sync with the simulation would love to hear what others have done.

Not looking for a specific product recommendation , more interested in the workflow people follow and the lessons learned the hard way.

Happy to share what I've tried too. What's working for you?]]>

I am trying to simulate sanding path with UR20 robot. The path motion is accurate, and I set speed and acceleration parameters similar to actual path. However, I am getting big differences between the cycle time. Simulation time is 33.1 seconds, and real time is 64 seconds. I do have some wait commands, but it is less than 3 seconds. This robot has some safety constraint which cannot be added in Robodk for example, elbow speed 350mm/s, tool speed 350mm/sec, but my speed is not even set to that high. Please see the attached Robodk study. I am not sure why there is a big discrepancy between two cycle time.

Thank you.

We have an upcoming project that requires the use of a precession stepping robot, which adopts a hybrid serial-parallel mechanical structure.

At present, we have not yet obtained the 3D CAD model of this robot. We will coordinate with our client promptly and provide the model as soon as it becomes available.

We are writing to inquire whether the RoboDK software supports this type of hybrid serial-parallel precession stepping robot. If supported, kindly advise us on the detailed configuration procedure and the required documentation and materials.

Thank you for your support and prompt reply.

Best regards,

Scene extraction from RoboDK to Python is already working (robot model, obstacles, joint limits, start/goal configurations).
My current challenge is collision checking:
OMPL runs, but some generated paths are not feasible. I suspect the issue is with the synchronization between OMPL(Python script) and RoboDK’s collision checker (currently using

Code:
return self.RDK.Collisions() == 0

).
A few questions:

Has anyone successfully integrated OMPL directly with RoboDK?
How is collision checking handled in RoboDK’s internal PRM implementation?
Is there a way to query the minimum distance between the robot and obstacles, rather than only checking for collisions?
