RoboDK-Video-2025-03-10-16-47-44.mp4

I have 2 JAKA Cobots in the RoboDK simulation, cobot1 to pick a cylinder and take the cylinder to ring assembling position, and finally feed the cylinder with the ring to the welding station. cobot2 to pick the finished product and place it in the box.

The 2 Cobots have to run independently and synchronously while they communicate with each other and the welding machine by I/O signals.

I found it difficult to make the simulation using robodk. It's easy to achieve in roboguide or robotstudio for the reason that each robot has its own controller, while robots of robodk share the same main program.

I gave it a try using thread function which is Not satisfactory, as we can see in the video: cobot1 has to wait for cobot2 before feeding, because of the call instruction.

anybody know how to simulate 2 robots in robodk smoothly as we can do using roboguide or robotstudio?

Reinstalling the robot system with irpicktool option and the tracking deviation issue solved.

I have a Fanuc M-10iA/7L used for Circular Tracking Painting, Automatic robot movement deviation has been reported by engineer from taught trajectory: Robot moves differently in automatic mode compared with the same trajectory in teach mode. We took a test in the roboguide cell built by on site all files backup.

and it's interesting that the nominal tracking frame changed after an automatic run.

left picture show the location of nominal tracking frame and trajectory when the $enc_count is "1"；

after a cycle start of PNS0115 using $ENC_SIM_ON, the trajectory and tracking frame rotated around the origin.

and the right picture show the location of the nominal tracking frame is far away from the previous location.

Anybody happen to know

1、the case of Automatic robot movement deviation has been reported by engineer from taught trajectory: Robot moves differently in automatic mode compared with the same trajectory in teach mode.

2、the difference of tracking frames shown in the two pictures.

many thanks.

use a mouse which can be connected to USB port on TP to close the windows?

I want to test robot interface module, but got nothing when I googled "Fanuc Robot Interface download" or searched in the fanuc website. there was no useful download linkage or any demo Tutorials.

Could anybody know where to get the latest Fanuc Robot Interface files?

GO Config is ok, so it's your karel program issue.

1. guess that .pc is background running? so condition will force the GO value...

2. replace POS_TOL 0.1 to a bigger value , e.g 1 and try again

Thanks for your response.

The point is the configured Digital Output Signals do not respond with corresponding Group Out Signal.

when robot is at home position, Group Out #2 signal Ought to be number 1 which means the robot is Home.

I have no idea about PaintTool, sorry... It seems that the GO is controlled by a KAREL program. Is your IO configuration a default PaintTool setting or did you do this by your own?

I took the test with a virtual robot created using onsite backup files, I also test with a default PaintTool setting, and neigher way works.

But, it works as the instructional video of youtube when I tested with a default handtool setting.

All the tests are done in the roboguide.

I check the Group Output signals configuration which is correct.

Group Output[2] Signal shows number 1 after moving robot to "Home" Position while the corresponding digital output signals take no change.

I take the test with painting tool, and everything works all right with handing tool.

So....

Has anybody happen to know the cause of this Group output signals problem?

Hi Guys:

As you can see from the left picture above, I turn the do[91]/do[93] on, and the GO[2] should be number 5 while it responds with nothing. It's shown in the right picture that I group out number 2, and the corresponding digital out signals don't change.

A Plan of Robotic Press Assembly is provided by mechanical engineer to evaluate whether it is possible or reasonable.

Fanuc M-20id/35 is used to press a screw into the steering object 50 mm with the robotic downward force.

The Slide of Press Tool can not move in the process, and the pressing force is required to be 300 N.

So, 1、 does anybody happen to involve in this kind of robotic application,

2、what kind of risks are behind this plan?

3、From which aspects should we start the evaluation?: payload inertia / moment of J4 J5 J6?

Thanks in advance.

The GO(16)[paint totals] configuration is shown as in pictures.

Hello to Everybody who sees this thread.

We are having a bus painting project which has 2 P-250ib Robots on rails. The bus is a huge object to paint and Paint consumption per vehicle body is way more than small car and that is the most likely cause of Paint Totals Data Anomaly we find in TP or from Paintwork Interface.

We want some help in solving the issue and what steps should we take to resolve this issue?

Do you have a backup of your programs (+ the line number of this trajectory) + the log file.

At home, thyssenkrupp integrated 2 UR, I had the same phenomena + emergency stops for overload or bad payload or collision. All my problems came from poor programming of my trajectories (acceleration, speed, choice of movement)

could you please send me your email, I can deliver the UR backup files to you.

for the oversize, I cann't attach the files here.

For the time being, I am asked to do the regional robot manufacturer study. and I happened to find that one of estun robot models( Chinese top robot brand) can rival its targeted Fanuc robot model except that 3/4 axis motion range of domestic products obviously worse than that of Fanuc when the load and arm span are almost similar.

what confused me is that: why estun robot manufacturer missed these obvious weaknesses while it can rival fanuc robot from the technical data view. Is there anything behind the gap: software/hardware for example.

There are Two Grippers for the Application: Gripper #1 and Gripper #2. The Robot has to switch to Gripper #1 after transferring work piece to Secondary positioning table using Gripper #2.

It's not a big deal in real world, but Is it possible to complete the simulation with roboguide, and what's worse is that each of these 2 grippers has fingers. I have searched a blogger showed a way of tool quick change simulation with "Part", but how to simulate the fingers motion with parts?
