Hi!
First of, sorry for all the questions.
I´m trying to create a “roller table”, similar to a conveyor belt but I can´t get the movement of the rollers working. I´ve been looking through the guides and tutorials and I did not find anything.
The part where (at least I think) I´m getting lost is around joint-link and how to do this.
What I want to create is a cylinder (from a mesh) that rotates and moves objects that “lands” upon it forward when told so.
I´ve been looking in the existing conveyor belts but there is really not that much info about how they work.
Best,
Martin
Hello!
To create the rotating cylinder, start with adding a joint + link and add the cylinder both in the visual and as a collision element in that link.
Then add a joint_motor element in the joint. Now make sure that both the axis of the joint itself and the joint_motor axis are set to the correct value, if you want the cylinder to rotate around the y axis they should both be set to ‘ry’.
The next step is to give the joint_motor a value. This will make the cylinder rotate. To control this from the behavior, add an output variable and connect it to the joint_motor value. Note that the value should be set to 0.0 when initializing, and then set to the proper value when the emulation starts.

Hi Martin!
Thank you for your reply! I finally found what i was doing wrong, I did not have any value on the joint_motor and i had to much margin.
I hope you go to bed with a feeling that you made someone’s day today, because you sure did!
I have a feeling that once I learn Simumatik it will be indispensable and so far it has proven to be very addictive!
Thanks again!
Happy to hear everything worked out!
It can be addictive for sure

Hi!
Could someone elaborate a bit in general around how to get something moving without giving it a Value in the joint_motor. I have tried using a AC motor now for a while, connecting it the same way as in the Basic tutorial 2 but a just can´t seem to get it going.
Earlier Martin mentioned behavior, but thats not used in the basic 2 to get i moving with a motor, do i need it?
I also have a problem with objects “loosing” its movement when you have not edited the object for a while. As soon as I go in to the editor, without changing anything and then save and reload it moves again. Does anyone else recognize this?
Best,
Martin
Try looking in the xml editor. There you should find a connection connection ‘motor_axis.value’ → 'j1.j1_motor.value.
I’ll look into this some more.
