Ivan,

For each of those setups, what are the results of 'rosrun tf tf_echo
<frame1> <frame2>' , where frame1 and frame2 are the pair of frames
that you are using the static_transform_publisher for? If the
static_transform_publisher is not responsible for the entire transform
from /laser to /odom, you may have an issue elsewhere in your tf tree.
