Re: ros_control / vrep connection model
Hello Coppelia, Thanks for your answer. For mode 3, I was actually thinking about running vrep in real-time as well - because my aim is to make the full setup look like reality as much as possible. Does that change anything to your statement: " 3. is not appropriate at all, since the time will ...

ros_control / vrep connection model
Hi, I am currently setting up a system where vrep is used as the simulator for a robot which will be built in real in a few months. I'd like to use the same control architecture for my real and my simulated robots. The control is performed using ros_control and the connection between the control mod...

Re: Unexpected behavior of simRosSetJointTargetVelocity
Interesting, I did not know there was such a synchronous mode for ROS. Thanks.
PS: I'll probably ask some more about it in the future, but this will be another topic.

Re: Unexpected behavior of simRosSetJointTargetVelocity
Hello coppelia, The first part of your message (on service calls being blocking) is clear to me. Now for the second part, I am not sure I understand what you call the synchronous mode within the ROS context, from reading http://www.coppeliarobotics.com/helpFiles/en/externalControllerTutorial.htm it ...

Unexpected behavior of simRosSetJointTargetVelocity
Dear all, I have written a service call to update the target velocities of some vrep velocity controllers and it turns out not to behave as expected. I call it 4 times (once for each controller) and I was expecting the target velocities to be updated simultaneously. Though I observe a slight time of...

Re: ros_control with v-rep
Hello coppelia, I am indeed looking for a synchronous trigger of my ros_control controllers. I was expecting something like a callback (subscriber) on vrep update... so is the info topic published synchronously with the physics udpate steps? If not, do you know at which rate the info topic is publis...

ros_control with v-rep
Hi, I am currently trying to put in place v-rep together with ros_control. I would like to update the controller_manager at each simulation step (you confirm this is the best practise, no?). Now my question is, how can I let my node know that v-rep has finished computed a new simulation step? Is the...

Re: Range selections in hierarchy
This is not a very conventional way to implement range selections but it works fine. Thanks.

Disable parts of the hierarchy
Hi, Sometimes it is useful to temporarily remove some parts of the scene, so the simulation does not include a joint or a link and their children. i.e. you have a mobile manipulator, that is a mobile platform carrying an arm and you only want to simulate the mobile for a few session to concentrate o...
