Circular conveyor belt

yangkang vor 2 Jahren aktualisiert von Support vor 2 Jahren 1

Hi

I wanted to achieve a circular conveyordemo effect (Fig1), a reference to radialConveyordemo (Fig2), but the MU transported in a circular conveyordemo is skewed in position, and I froze the XYZ rotation of the MU

Questions about the use of s7 PLC

ZhangFengMing vor 1 vor einem Tag aktualisiert von Support gestern um 03:07 1

When using S7Interface, some S7Interface can connect to many points, and some S7Interface will be disconnected if the number of connections is too large, please see the picture, as if: Negotiated Pdu Lenght is related to this value. May I ask how Negotiated Pdu Lenght is set? Why is it 480 or 240? If Negotiated Pdu Lenght is 240, too many signals cannot be connected.
There is also a question about: how to use the Area Read Write Mode, if I need to read 56 points from the PLC's DB block and write 12 points, how should I fill in the configuration.

Looking forward to your reply very much!

Hi, I can't tell you in detail why the negotiated Pdu lenght is like that. We use Sharp7 as a basis library for the S7 communication. I think this defines the length of the telegrams but it does not defines the number of the signals. If needed multiple telegrams are send for covering all signals. On AreaReadWrite Mode you sould enter min and max adress - so if your DB is 100.X to 140.X you should enter 100 and 140.

Bag is not moving with RGV

Kantale vor 3 Wochen aktualisiert von Support vor 2 Tagen 1

A693 - Windows, Mac, Linux - Unity 2022.3.3....mp4

I want to move the bag which is shown in project with RGV. But unable to do it. When i am giving forward command to RGV, RGV is moving forward but the bag is not moving with RGV. Last time you had shared a link for reference (https://doc.realvirtual.io/components-and-scripts/motion/transportsurface#transport-surfaces-and-unity-physics).

But i couldn't get it. Please suggest the solution step by step.

Problem with Drive with AGX

Miel Pieters vor 1 Monat aktualisiert von Support vor 2 Wochen 7

Using Realvirtual Release 2022.18 Build 5747

I'm trying to enable a drive while using AGX Physics for collisions.

This is the scene I'm using for testing. I'm trying to move the beam on top of the platform and have made colliders in AGX for both. Then I configured a prismatic constraint on the beam through AGX.

Then I followed the instructions of https://doc.realvirtual.io/extensions/agx-physics

Image 1250

I set the lock on of the constraint of the Rigid Body.

Image 1251

Then I configured the Drive. I put direction on Virtual. Then I added an Erratic Driver.

But when I run the beam doesn't move. Only when I disable the Rigid Body and put the Direction not on virtual the beam moves, but that means disabling AGX Physics. How can I make the beam move while still using AGX?

Taking too much time to import the step file.The size of step file is only 401 MB.

Hi, how long took it in total? Yes our Step file is not always very fast and it could happen that you need to wait more than 15mins for bigger files.

IK problem

hjl vor 1 Monat aktualisiert vor 1 Monat 2

1When using the trigonometric solution, was the DH parameter table used to unify and simplify the relative pose relationships between the joints and links of the robotic arm, serving as an auxiliary tool? Or was it purely a trigonometric solution without the DH parameter table?


2:Can I understand it as using a geometric solution, specifically applying trigonometric methods to calculate and handle the relationships between joints and determine the joint angles?

3:I'm using version 2021.05, and I'd like to achieve real-time IK motion for the robotic arm by directly dragging the TCP in play mode, just like in edit mode, where dragging the TCP instantly moves the entire robotic arm via IK. I don't want to drag the TCP to a position and then click "Drive to Target" to initiate the movement


4:Could you share the source code of the IKCalculator.dll file?

What method of IK is used here? DH method or something?

We are using a trigonometric solution which is able to calculate all possible solutions.
