I am having the same problem, could you elaborate on what you mean? Here's my post on the question: https://answers.ros.

I am trying to do obstacle avoidance with 2d laserscan from scratch. So I use urg_node for a laserscan sensor. In the float32[] ranges array in the laserscan.msg, it contains distance information. I am wondering how does it determine the size of the array. Also for each ray what angle would it be?

I found that if I set max and minx angle to + and - 2.09234976768, the size would be 683 (I did it by just printing ranges[i] until I get a ranges[i] = 0 because for some reason when I tried sizeof(msg->range), it gave 24 which is definitely not the size).

I don't get how in rviz they are able to figure the angle and the where the laser dot would be. Anyone know?

Edit: I found answer: #q198843.

ROS Kinetic:

I am using 2 robot and I am not sure how to display in in rviz with amcl. What I have is each robot has its own tf. I would do

<remap from="tf" to="tf1"/>

is that wrong? I think it is wrong because rviz can only take in one tf. I did some reading and it said instead to do.

<node name="robot_state_publisher" pkg="robot_state_publisher" type="state_publisher" >
<param name="tf_prefix" value="robot_0"/>
</node>

and

<node name="robot_state_publisher" pkg="robot_state_publisher" type="state_publisher" >
<param name="tf_prefix" value="robot_1"/>
</node>

Is one of these method right? Or is there another solution. Any help is appreciated! Thank you!
