Fetch doesn't pick up objects off of the ground

We are trying to use the code in the Fetch pick up demo, and trying to pick up objects off of the ground. However, it doesn't seem to detect objects on the ground. Does this have something to do with the object segmentation; does it need a table as a support plane?

I presume you're using the demo that uses the simple_grasping package, in which case you might need to set the voxel_limit_min to a negative value (or the ground plane may be getting chopped off). See

If that doesn't work, I'd suggest posting more details of exactly what you are running, and some RVIZ screen shots of what the point cloud looks like.
