Subject: [ros-users] [Discourse.ros.org] [MoveIt!] MoveIt! Maintainer Meeting Recap - July 25th, 2018




**Agenda**

-    Status of ROS Melodic


-    Building Melodic on Kinetic


-    Progress with GSoC students


-    World MoveIt! Day Planning


-    New OMPL interfaces


-    Potential Intel collaborations


-    Switching to reoccurring monthly meeting of shorter length




**Attendance**

- Michael v4hn Grner

- Robert Haschke

- Isaac IY Saito

- Jorge Nicho

- Dave Coleman

- Ian McMahon

- Bence Magyar

- Gijs van der Hoorn

- Mike Lautman

- Levi H. Armstrong

- Akiyoshi Ochiai

- Zack Kingston

- Will Baker

- Nathan Brooks

- Matthew K Hansen

- Mark Moll

- Andy McEvoy

- Sharron Liu



**Summary**



1 - Introductions

-    Matthew K Hansen from Intel


-    Zack Kingston from RICE's Kavraki robotics lab


    - Works in MoveIt!, Robonaut 2.0


-    Will Baker from Houson Mechatronics


    - Worked on MoveIt! with Robonaut


-    Nathan Brooks from Picknik






2 - ROS Melodic

-    MoveIt! migration PR still un-reviewed


-    Most users still on kinetic


-    No robot drivers, many packages still behind 


-    API changes in Melodic, pluginlib, TF2(ABI changes) , etc., make it incompatible with ROS- Kinetic. These changes bring ROS Melodic closer to ROS 2.0.




3 GsOC

-    Michael Grner update:  


     - Pull Request on grasping, grasp generation and tutorial.


     - Fixes to MoveIt Grasp Package


     - Detect Object button in Rviz being examined for possible fixes;  it currently does nothing.


-    Andy McEvoy update:


     - Mentoring student Mohamed.


     - Working on new features for the Setup Assistant that work with Gazebo and add improved visualization


     - ROS Control Integration in progress.


     - Grasping screen, not much progress.


-    Mark Moll update:


     - Working on improving CHOMP and STOMP 


     - CHOMP's original implementation is very brittle.


     - MoveiIt! Website now has tutorials on how to setup those planners.


     - CHOMP Author claims that planner has lots of downsides, especially when dealing with obstacles.


     - STOMP optimization framework is very promising, needs repository maintainers to be more responsive.


     - Collision refactoring issue is being addressed, a PR has been created.


     - More participation from industrial_move maintainers, add new admins to keep development from stagnating.




4 New OMPL interfaces

-    OMPL planner plugin refactoring allows new and existing planner implementation to load their own configuration, allows selecting planner types (joint planner, Cartesian planner) and reuse of configuration spaces.


-    Big internal API change, for external user it should look the same; behavior effectively remains unchanged.


-    Perhaps integrate into melodic?


-    Pull Request is being broken down into smaller PRs.


-    State Space discontinuity has been a long standing issue.




5 Intel

-    Matthew K Hansen and Sharron Liu


-    Focus in enabling ROS 2.0 for industrial applications.  Looking into enabling MoveIt in ROS 2.0


-    ROS2 Grasp Library Presentation:


     - MoveIt Plugin


     - Prototyped GQCNN (originally trained with Tensorflow) grasp method with Interl OpenVINO, 93% success rate was achieved.  Original implementation has UCB license (not-for-profit) so it cannot be used for commercial purposes.


     - Grasp Library Proposal, trained with caffe and RGBD image data.


     - Alternatives to TensorFlow or Caffe Can is OpenVINO which provides hardware acceleration benefits.


     - Goal is to create a ROS 2.0 Grasp Library with the option to enable OpenVIN.  A demo with the UR5 robot that works with MoveIt! will be created and documented




6 World MoveIt! Day

-    Planned for October 25th


-    Lessons learned document from last year is available.


-    Not very well advertised.  Official announcement soon to come.




7 Monthly Meetings

-    Will start scheduling monthly meetings.
