Problems with laser scan
I'm running hokuyo node and move_base on my robot, and found 2 issues in the operation:
(1) Obstacles seen when there are none around: Laser scan showed a long line comprising an obstacle when there was clearly none.
(2) Despite seeing obstacles close by, move_base collides with them. I'm sending scans in the /odom reference frame and using an identity transform for localization. I'm guessing this is an issue with robot base footprint?
