Hi!

I am currently working on a pick and place application, using move_group interface. After bringing the gripper around the collision object, i attach it to the end effector:

group.attachObject(collision_object.id);

Then picking it another place, i detach it:

group.detachObject(collision_object.id);

When i detach it, the box stays with one edge on the groud, one in the air. How could i fix this? Please help me, Thanks

the box stays exactly where you put it, ie there is no physics simulation in rviz. If you need that, have a look at gazebo

I'd put it even stronger: RViz is not a simulator. It's purely visualisation.

To be even more clear: Detach in moveit only states: "When the manipulator moves again the object won't be moved with it", attach is the opposite. Objects never move on their own.
