Hector Slam with Raspberry Pi 3, RPLIDAR A1 and Laptop

edit

Hello to everyone :)

I want to build up a little car and on its top there should be a RPLIDAR A1 which is connected to a Raspberry Pi 3. After scanning the room I want to visualize everything with Rviz on my Laptop. So my plan is to start Rplidar on my raspberry pi and than I want to start hector slam on my laptop. Im using ROS kinetic and ubiquity on my raspberry pi. On my laptop im using ubuntu 16.04.

I have correctly networked the laptop and the raspberry pi 3. The laptop (MASTER) is for viewing and processing the Scan and also receiving the data from the Raspberry/Rplidar. I'm able to view the data on my MASTER laptop, using Rviz. I'm then running the hector_slam package on my MASTER, with the following mapping_default.launch file---

(the actual launch file)

<launch> <arg name="tf_map_scanmatch_transform_frame_name" default="scanmatcher_frame"/> <arg name="base_frame" default="base_link"/> <arg name="odom_frame" default="base_link"/> <arg name="pub_map_odom_transform" default="true"/> <arg name="scan_subscriber_queue_size" default="5"/> <arg name="scan_topic" default="scan"/> <arg name="map_size" default="2048"/>

<node pkg="hector_mapping" type="hector_mapping" name="hector_mapping" output="screen">

</node>

   <node pkg="tf" type="static_transform_publisher" name="base_to_laser_broadcaster" args="0 0 0 0 0 0 base_link         laser 100" />

     </launch>

When i launch rplidar, Rviz opens and i can see the Scan on the map. Than than i type "rosrun tf static_transform_publisher 0 0 0 0 0 0 map scanmatcher_frame 10". I did this because I was getting the warning "No transform between frames /map and scanmatcher_frame available after 20.002338 seconds of waiting. This warning only prints once.". Then i launch hector slam and another Rviz opens with an empty map and the terminal shows the following message:

[ INFO] [1576537404.723676302]: lookupTransform base_frame to laser timed out. Could not ...
