aero on melodic

[sasabot]

I'd like to know if anyone has succeeded or encountered similar issues. It seems that the functions around MoveIt crashes with melodic (cannot proceed the setLifter test in fullbody_test). Probably has something to do with the Affine to Isometry update.

Below is a temporary not so splendid solution that avoids the problem but does not solve the problem. Thanks.

$ git clone https://github.com/ros-planning/moveit
$ cd moveit; git fetch origin 0.10.8
$ git checkout -b 0.10.8 refs/tags/0.10.8
$ catkin build

[update] seems it was not the problem of using Isometry, but something due to moveit above version 1.0 (not sure what though)

Tests were passed at that time (March 13?) https://travis-ci.org/seed-solutions/aero-ros-pkg/builds/505707425

[YoheiKakiuchi]

~~This PR https://github.com/ros-planning/moveit/pull/1382 is the cause of this. (If this PR is removed, all tests pass)~~ It's wrong

tests do not pass at 1.0.0, test pass at 0.10.8

[rhaschke]

Did you try MoveIt release 1.0.1? This includes https://github.com/ros-planning/moveit/pull/1382.

If you still have issues with MoveIt > 0.10.8, please perform a git bisect to narrow down the offending commit.

[YoheiKakiuchi]

@rhaschke This is the first commit that causes the error. https://github.com/ros-planning/moveit/commit/5bedb7a31db8ab4ac7e474de762e5dfc42ad4d13

The error is something like 'double free' This commit just does refactoring, I think. I have no idea what's wrong.

@sasabot, I tried to replicate your issue locally, but you need to provide more information: What are the exact steps to reproduce the problem? Just calling rosrun aero_samples fullbody_test_node, does nothing...

[YoheiKakiuchi]

@rhaschke Thanks for testing

We tested it by git bisect with https://gist.github.com/YoheiKakiuchi/ec0220af9305e90a65ec67d4e2cf6115 https://gist.github.com/YoheiKakiuchi/941d2eff594249da4950e1a2f7f45c1f

The difficult point for building aero-ros-pkg are,

at first you should build aero_description

catkin build aero_description

https://gist.github.com/YoheiKakiuchi/941d2eff594249da4950e1a2f7f45c1f#file-dockerfile-melodic-L34

after that, you should ./setup.sh typeF in aero_desctiption https://gist.github.com/YoheiKakiuchi/941d2eff594249da4950e1a2f7f45c1f#file-dockerfile-melodic-L36-L38 (it is for building indicated(typeF) robot model file, etc. )

then you build aero_samples and run rosrun aero_samples fullbody_test_node

[rhaschke]

@YoheiKakiuchi, these steps I already managed. However, running rosrun aero_samples fullbody_test_node, just outputs the following debug message: [INFO] ros.aero_std: start creating robot_interface

Other than this, I don't get any output or CPU activity. Is this intended?

[sasabot]

@YoheiKakiuchi @rhaschke Thank you for investigating. To run the samples, you also need to run a dummy robot controller. roslaunch aero_startup aero_bringup.launch after running the dummy controller (keep this launched), and then running rosrun aero_samples fullbody_test_node the sample should proceed.

[rhaschke]

Thanks for this hint. Now I the following are reported on the command line:

You should fix your .srdf file(s) to handle them. Finally, there is a free(): invalid next size (fast) Interestingly, I don't see this issue when running with a memory sanitizer. Looks like a timing/synchronization issue in the fullbody_test_node code.

[rhaschke]

I was able to track down the issue: it's related to the two mimic joints in your "leg". I will file a PR for MoveIt to fix it.

[rhaschke]

@YoheiKakiuchi, can you confirm that https://github.com/ros-planning/moveit/pull/1490 resolves your issue?

[hi-kondo]

I checked moveit demo.launch , so error and segfault on melodic. I tried to control lifter on move_group.

Didn't it fix yet?
