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.
can you please send us the output of the terminal where you started
Code:
/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?
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?
