No motion plan found #47

In the pick_up_item.py the bot is not able to find any plan for the motion. Can you please suggest anything.

Hi Sachin,

Unfortunately that is a generic message of planning failure that can be caused in many ways. I usually debug this by launching rviz and looking at the planning scene. Often then you can see if (for example) the robot is too far away from the object, or various other things have gone awry.

Motion planning is a complex topic. I'd suggest diving into the documentation of MoveIt, such as this page, and experimenting with simple standalone systems to get a feel for what is going on behind the scenes: http://docs.ros.org/kinetic/api/moveit_tutorials/html/doc/quickstart_in_rviz/quickstart_in_rviz_tutorial.html

Cheers
