Universal Robot in Robotexpert


We are looking into using universal robots in manufacturing to assembly parts together.  How well does Siemens NX robotexpert work with Universal robots? 


Any one care to share their experience with this robot using robotexpert? 


We do not use robotexpert at this time.  I have found the 30 day trial. 


What is the typical learning curve of this software?

You will be able to simulate URs using the default controller in Process Simulate/Robot Expert.

However, UR controller is available, but license and setup are not included in the RE-trial-version.

You may ask your SPLM-sales for a full trial.

Regarding the robot-model you may ask the GTAC helpdesk.


Learning curve: usually one week training and after a few more weeks you are at 90%.

But you never stop learning ;-)

Hint: there are also self-paced webcast trainings available ("Learning Advantage Membership"), but a personal training is always better.


Btw: it's not based on "NX", just Robot Expert


Re: Universal Robot in Robotexpert


Great feedback.  thanks.


Is it possible to import objects into Robot expert?  VIA step NX native or parasolid?  Can you move these around easily into position? 


Also does this write the code to export to the robot to be able to run it?


I am new to this stuff.  Sorry for the simple questions. 


We have a gold learning advantage I will look into this.  Thanks for this tip.


thanks again.

Of course RE can import geometry from different sources.

The base of all is JT. An open and ISO-certified standard viewing format.

There are bidirectional native translators for all relevant CAD-systems in addition to several standard formats like STEP.

And yes: you have full control of your layout. You can even open components for modelling and add kinematics or geometry. (RE is no CAD-competitor, but allows basic CAD-modelling features like drafting, extrude, boolean operations, ect).


"Write the code to the robot" is what we call "Offline progamming" (OLP).

This is the core competence of RE/PS and the previous product Robcad since the 80's.

Almost all industry relevant robot-controllers and -models are available.

About CAD conversion:

From RobotExpert release notes:


RobotExpert supports the following CAD formats:

• NX8, NX8.5, NX9.0 (64bit only)
• CATIA V5: R8 to V5-6R2014
• ProE: WildFire5, Creo Parametric 1.0, Creo Parametric 2.0
• IGES: 5.3
• STEP: AP203/214
• SolidEdge ST7
• Solid Works 2014
• Parasolid x_t files, up to version 26
• JT: up to 10
Prior versions may also be supported.

Support for newer versions of these formats are added gradually along time.

All is available in the trial version. For NX conversion, license and NX installation is required, for others, only RobotExpert.



Re: Universal Robot in Robotexpert


Thanks for the feedback.  This is exactly what I was looking for.  I went through the Learning advantage and we will have to take a look at this software.  Only thing we are on NX10 and it only supports NX9.  Nothing but a step file or JT file will not solve.

FYI: models for UR3/5/10 are already made, but some modification are still going on.

It's a matter of a few days/weeks, to have them available on GTAC.

Re: Universal Robot in Robotexpert


that is great.  We are looking at the ur10 robot for doing most of our major assembling.  Thanks again.

Re: Universal Robot in Robotexpert


How accurate are Cycle times vs real world applications?  Can RE optimize cycle times? 


Thanks for the feedback

You are welcome Smiley Happy


Regarding NX version:

I'm sure this is only due to a not uptodate text in the release notes.

We definitly do support our own product's new versions ;-)


Regarding accuracy:

Robot time-behavior and motion-planning is very much related to the controller.

Usually you will you an RCS-module, that can be purchased at the robot-vendor.

It runs as a plug-in in the background and is aligned with the correct manipulator and firmware-version of the controller.

As the RCS (Robot Controller Simulator) comes e.g. from Kuka, it calculates it's time and motion using the Kuka algorithms. So this is very exact.


Regarding optimization:

This is unfortunately a domain of Process Simulate's APP (Automatic Path Planner).

PS is the same platform as RE, but allows many more processes.

E.g. logic behavior, sensors/actors, PLC-connection (virtual commissioing)

PS is positioned as our high-end-product.
