ethzasl_icp_mapping not moving forward while registering.

edit

Initially map moves forward a little bit but after that it just keep on adding points standing still at the same place. Is there problem with the launch file? I am using velodyne-32-E and configuration file from artor.

this is the launch file I am using:

    <launch> 
<node pkg="velodyne_driver" type="velodyne_node" name="velodyne_driver">
    <param name="model" value="32E"/>
    <param name="pcap" value="/home/administrator/Desktop/data/tunnel.pcap"/>
    <param name="read_once" value="true"/>
    <param name="frame_id" value="velodyne"/>
</node>

<node pkg="velodyne_pointcloud" type="cloud_node" name="cloud_node">
    <param name="calibration" value="$(find velodyne_pointcloud)/params/32db.yaml"/>
    <param name="min_range" value="3.0"/>
    <param name="max_range" value="130.0"/>
</node>
