So, I'm trying to measure the feasibility of a simulation, and since I didn't find an example like this, I will ask.

There is a way to simulate a conveyor tracking inside RoboDK?

I'm assuming there should be a way to achieve this with some Python black magic, but I'm wondering if there is some trick to facilitate the process.

The idea is that robot will drop a part on a jig, that is mounted over a moving conveyor, and since conveyor will not stop, the robot must down to drop the part synchronized with the jig movement.

Hi massula,

There is a trick to simulate the pick and place on a moving conveyor without the use of python.

You can place the target inside a referential in the moving mechanism and add a offset to deal with the refresh rate.
You might need to adjust the offset, depending on the speed of the conveyor & simulation to make it look accurate.

If you want the object on the conveyor to be on a very precise spot, you can hide the object you just placed & show an object that was already on the conveyor when you drop it.

I hope this help,

Olivier.

Nice to know, Olivier.

I will check this in the next days

Thanks!

Hi massula,

here is a small example concept on how it would work.

Thanks, Olivier!

I opened the simulation here and it is exactly what I need.

Nice job @Olivier.

Hi Everyone! How can i make something same but with painting part on conveyor?

[Olivier]

Do you mean a curve follow project on a moving conveyor?

Hi, please I am trying to achieve vision - guided conveyor tracking of moving parts in RoboDk. I am using Ur5e, Onrobot Eyes, Onrobot RG2/SoftGripper and I intend placing the product in a package and arranged. 
my biggest challenge is with the vision-guided aspect. Please I will be so happy to get any help to be able to achieve this in RoboDK. 

I have done the physical setup of the station but the one in RoboDk will be like a digital twin of the real thing. Thanks

You can find vision-based examples in your Python examples, such as hand-eye calibration, object detection in 2D, depth camera simulation. You can then use the API for visual servoing.

I suggest starting with conveyor tracking using our examples, without vision, and adding vision afterwards.
