Dear Eurocers,

i recently updated to the newest scene deb package and i'am now encountering a problem when grasping a cylinder.
Shortly after grasping a cylinder (in task1v1, task1v2 ...) the gazebo sim time stands still (< 2 sec sim time after the grasp).
Gazebo is then completely unusable.
As soon as i change the material "aluminium2" to "aluminium" in the task yaml files, i can grasp the cylinders again.
I don't have any problems with grasping the other objects, so i think this is only related to the new material introduced in the 1.0.19 scene file.

Greetings

can you please send us which euroc-c2s1-simulator your simserv is using?

simply ask dpkg (within the simservVM or your native setup):

Code: Select all

$ dpkg -s euroc-c2s1-simulator

i will then try to reproduce this.

Depends: libboost-program-options1.46.1 (>= 1.46.1-1), libboost-system1.46.1 (>= 1.46.1-1), libboost-thread1.46.1 (>= 1.46.1-1), libc6 (>= 2.4), libgcc1 (>= 1:4.1.1), libprotobuf7, libstdc++6 (>= 4.6), libtbb2 (>= 2.1~), python-yaml, python-numpy, python-lxml, libboost-python1.46.1, libtinyxml2.6.2, libavcodec53, libavformat53, libswscale2, libtar0, libgts-0.7-5, libogre-1.7.4, libcegui-mk2-0.7.5, ros-hydro-desktop, euroc-c2s1-scenes
Description: this is the European Robotics Challenge 2 stage 1 gazebo-based simulator
it includes binaries of a sligthly modified gazebo-2.2.1 as well as
a gazebo world-plugin to implement the different challenge tasks.

Btw: This is a setup on a native machine, not a simserv VM.
We are able to reproduce this error on another machine in our lab.

can you please send us the output of the terminal where you started

Code: Select all

/opt/euroc_c2s1/start_euroc_task_selector

in? (copy & paste)

in case the gzserver is still running a core dump of that prozess would be helpfull. you can create & upload a core dump with the upload_core script.
so in case the gzserver just seems to hang (no further output on the console and sim time in viewer stopped...) please create a core dump like this:
$ sudo /opt/euroc_c2s1/bin/upload_core YOUR_TEAMNAME gzserver

this might take some time to generate and then upload the coredump. please notify us here or via the mailinglist support-challenge02@robotics-challenges.eu when you've uploaded a coredump. the coredump will not be public readable.

can you please try to install the new scenes & simulator package on your simulator host: euroc-c2s1-scenes_1.0.25_i386.deb and euroc-c2s1-simulator_1.0.24_i386.deb and test whether it still happens?

i was not able to reproduce the problem you described and without further debugging information a can't do more. i hope those package versions happend to fix you problem as it might be related to this: http://euroc.iphpbb3.com/forum/viewtopic.php?nxu=20112706nx57588&f=4&p=456#p456

thanks for the new releases. It seemed to fix the problem for me.
Thanks alot!

Btw: If i upload a logfile created with the new scenes/sim package to the intermediate evaluation, it will be rejected with a "unknown scene" error.
Do you know when it's possible to upload the log files again?

[fschmidt]

i uploaded all new scene hashes to the web-evaluation. your logs from unmodified scenes should get accepted.

[eurocer]

Works great. Thanks alot!
