Re: V-REP gradually slows down in Docker

Hi Copellia,

I tried this and got the same result. Both the CPU usage and memory usage keeps increasing.
Note that this only happens when running in a docker container. Any ideas for what to test next?

Best Regards,
Mathias Thor

Re: V-REP gradually slows down in Docker

On closer inspection, it looks like vrep is using more and more memory+CPU after each reset.
What could that be?

Re: sim.launchExecutable does not work in true headless mode

I was not able to spot the problem.

However, a temporary fix is to use the following (on Linux):

Code: Select all

     os.execute("Program PATH" .. " "Program PARAMETERS" ".."&")

Re: V-REP gradually slows down in Docker

Dear Coppelia, Thank you for answers. I do not use simx_opmode_streaming and the simulation is also getting slower when using ROS to start and stop the simulation (where I also check that the simulation, in fact, is stopped and started). Is there anything else that I should be aware of when resettin...

V-REP gradually slows down in Docker

Dear Coppelia and fellow programmers, I am planning to use V-REP for Reinforcement Learning and I would, therefore, like to run several v-rep instances in parallel. For that, I use Docker to create v-rep containers. However, my simulation is gradually getting slower as it is being stopped and starte...

sim.launchExecutable does not work in true headless mode

Dear Coppelia and fellow V-"REPPERS", I have successfully recompiled V-REP in headless mode. However, sim.launchExecutable now fails to start executables (in my case a controller written in C++). Does anyone know why this is? It seems like the rest of the LUA script is executed as expected. Best Reg...

V-REP Update

Hi,

I enjoy working with V-REP on a daily basis, but it seems like a long time without any updates.
When will we see a V-REP 3.5.1 or 3.6.0? And what is it expected to include?

Best Regards,
Thor

Re: Prismatic joint in spring damper mode gets stuck

So here are my findings if anyone is facing a similar problem. The normal way of modelling a spring in V-REP is to use a prismatic joint set to spring-damper mode. However, this method turned out to be unstable and imprecise. The spring can instead be modeled as a revolute joint with the z-axis perp...

Re: Prismatic joint in spring damper mode gets stuck

Hi Coppelia,
I am using Vortex, so that is unfortunately not an option.
I tried to play with the target velocity, which helps. However, it makes the joint very shaky and unstable.

Best,
Mathias

Prismatic joint in spring damper mode gets stuck

Hi everyone, I have a problem with the prismatic joint in spring damper mode. I am using it in the feet of a hexapod robot. When it presses down on the joint (i.e. stepping with the foot), then it is compliant as expected. But when it lifts the foot again then the joint is stuck and does not return ...
