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 ...

Problems with using rosinterface - synchronous mode

Hi all, I am currently trying to sync my v-rep simulation with a ros-node written in C++. From the C++ ros-node, using the RosInterfaceHelper tool, I am enabling the sync mode and triggering the simulation every time I loop through my controller program in the node. So the C++ node loops the followi...

How to add graph to page view

Hi,
Is there a way to dock a graph into a page in VREP 3.5.0 (see https://i.imgur.com/yQvNS9k.jpg)?
I remember that this was possible in the earlier versions, but it does not seem to be the case with 3.5.0?

Best,
Mathias Thor

Re: Flexible joints

I just wanted to add that it is also possible to add "relaxation" to a joint by editing its engine specific properties. I, for instance, added relaxation to a joint using the vortex engine such that it is allowed to move a bit in the z-direction (i.e. some compliance in the z-direction). Best, Mathi...

Problems with resetting robot back to initial position

Hi CoppeliaRobotics, I'm currently working on a project where I to repeat an experiment multiple times. I'm controlling my simulated robot through ROS, so I thought that the smartest thing would be to just reset to robot back to its initial position and orientation (that way I do not have to stop an...
