We talked about the latest MoveIt! update to 0.7.1. That change introduced several important/convenient new features, one of which is that you can now set the default planning algorithm (relevant ticket on github).
Before this change, LBKPIECE was set as a default planner and it wasn’t clear for the users how to make a change for it. The algorithm has reportedly not been finding solutions when working with MoveIt!, e.g. in our ROS introductory workshop we have to ask participants to go through counter-intuitive steps to change the algorithms for DENSO robot.
The new feature allows you to choose algorithm of your choice, e.g. RRTConnect.
If your robot already comes with moveit_config package but has not utilized this feature, you might as well do so.
