Re: [dumbQuestion] launching v-rep from launchr bar in Ubunt

The problem is that the unity launcher will not spawn a login shell, so it will not source your .bashrc (which is the shell initialization file where you usually load ros stuff, like sourcing /opt/ros/DISTRO/setup.bash). Since I need ROS, as a workaround for this, I created a launcher (put this in v...

Re: problem with depth sensor when running Linux in VM

Nope, also the Mesa SR4000 sensor gives me a black depth image (but RGB image is OK) when running in a virtual machine. Note: I think I erroneously assumed it was a 3.1.0->3.1.2 regression, because it worked on my lab pc with ubuntu 13.04 and vrep 3.1.0, but the same scene running on virtual machine...

Re: problem with depth sensor when running Linux in VM

Nope, I didn't solve it.

I tried all six combinations of {offscreen surface, invisible window, visible window} x {Qt, non Qt}, but none of them fixed the issue.

Re: problem with depth sensor when running Linux in VM

It seems a problem with the graphics driver when running ubuntu in a virtual machine (I updated topic title accordingly).

Re: 3.1.2 possible regression for SICK S300 sensor

It seems the RGB information of a vision sensor is there, but the depth information is not.
(note: I'm running in a virtual machine, Ubuntu 14.04)

As a double check can you suggest me a scene where the depth sensor is demoed so that I'm sure to be testing it properly?

problem with depth sensor when running Linux in VM

I'm using V-REP 3.1.2 linux 64-bit, and I'm unable to get correct readings from the provided SICK S300 sensor. It used to work in 3.1.0, but in 3.1.2, if you set script parameter showLaserSegments=true, you'll see that laser segments look like if they are "inside" the sensor mesh. Screenshot: http:/...

Re: ros: restarting simulation... useless api StartSimulatio

Here is what I do: simulation now is running: $ rosservice list | grep simRosSt.*Simulation /vrep/simRosStartSimulation /vrep/simRosStopSimulation $ services are there... let's stop the simulation: $ rosservice call /vrep/simRosStopSimulation "{}" result: 1 $ now I wait until the /vrep/info effectiv...

ros: restarting simulation... useless api StartSimulation

I'm running V-REP headless for simulating my robot in ROS. I sometimes need to restart the simulation (e.g. the robot falls off the simulation scene :D) but once I stop the simulation with /vrep/simRosStopSimulation, no ros services for controlling V-REP are available anymore, so it is not possible ...

Re: how to avoid deformable or bending links

Also, lowering the masses (I've changed them to 0.1, 0.15, and 0.2 respectivelly) seems to help a bit.
However the effect never goes away (both in Bullet and ODE).

Re: how to avoid deformable or bending links

Is it relevant that joints do not physically touch the link object?

To me the link object for the bogie and the two flippers it was not relevant (I could have used a dummy if only it allowed maintaining dynamically enabled joints), so I created a 5cm x 5cm pure plane with mass 0.3 Kg.
