Re: Workspace visualization
Yes, it outputs the error, the same as above. Here is my minimalistic scene: https://www.dropbox.com/s/mauego992i3s6gy/torsoWorkspace.ttt?dl=0 I was using CoppeliaSim Edu v.4.1.0. As you can see, the point cloud is calculated for one UR5 robot, which is dynamic, but the arm then falls down. The scri...

Re: Workspace visualization
Hello, I figured out what the problem was. I have a tree-structured kinematic chain, a sort of torso with 2 UR5 arms mounted at the top. The arms were connected via force sensors and were dynamic. As soon as I made each arm orphan the codes did work. However, I now have another problem. If I make th...

Update scene examples with new functions
Hello Coppelia! This is not precisely a feature request, more of a suggestion. I find your examples in scenes folder very useful. I just have a small remark. You often fix many bugs in new versions of Coppelia and add new functions or deprecate old ones. However, the code in the example scenes still...

Workspace visualization
Hello Coppelia, I'm working on a scene with several UR5 robots, and I wanted to visualize their workspaces. Your scenes/workspace.ttt example proved very useful, but I do have 2 questions. In that example you use a deprecated function to create a point cloud: if usePointCloud then sim.addPointCloud(...

Re: Problems with force sensor
Hi
Thanks for the advice. When I make the upper part of the body non-respondable, I get a bit better results. I'm very interested to know what method the dynamic engines use to calculate/estimate contact forces? Is that something you could share?
Cheers

Re: Problems with force sensor
Hi
Here is the link:
https://www.dropbox.com/s/c0n8dsscm3t6x ... l.ttt?dl=0
I read the sensor in the targetMovements#0 script at line 231

Re: Problems with force sensor
Hi, The difference is quite large. For instance, with one engine forces would be around 4-6N, and with another, it would be around 20-30N. The movement of my robot is in a threaded script, similar to how you did it in the scenes/ik_fk_simple_examples/10-applyingIkToDynamicallyEnabledModels.ttt with ...

Problems with force sensor
Hello Coppelia, I see that there were some recent posts dealing with tool force control, force sensors, etc. I also have a problem with the results from the force sensor. The results that I get from it are very different depending on the dynamics module that I use. I expected them to differ a bit, b...

Re: forceVector a nil value
Just one more tiny question. I have a force sensor connecting 2 objects, and I want to measure the force with which one component is pressing the other. If I want to measure the z component of the force what is the direction of that force? If the sensor returns a negative Fz value, is it negative re...
