moveit collision avoidance

I am using default IK planner (KDLplugin) for planning the path for ABB_IRB4600 robot using moveIt RViz plugin. When i import an object and make the robot movement to avoid that object by publishing current scene in RViz . The movements of the robot becomes very weired. Is there a way to refine the movements of the robot during collision avoidance of the object in the planning scene. I tried to incease the planning attempts and the planning time but haven't acheived any good result.

In the RViz Motion Planning panel, under the Context tab, try picking a different OMPL algorithm. I find that RRTConnectkConfigDefault works well out of the box.

RRTConnectkConfigDefault looks good. thanks but still movements of the robot are not so refined as i want to have. It should go around the obstacle but it moves a bit far from the obstacle. any suggestion how to get linear movements around the obstacle

You could also have a look at ROS-I's stomp implementation: https://github.com/ros-industrial/ind... . This uses a whole different planning approach and should yield "nicer" trajectories.

I switched to stomp planner. The trajectories are really nice when i plan and execute using RVIZ plugin even around the obstacle. but now i am having problem with sending pose values since i think its only works with joint values.
