slam_toolbox::SlamToolboxPlugin' failed to load

[thomasco...@gmail.com]

Hi Chris,

SBC: Rpi 4B/4GB
OS: Ubuntu 20.04.3

ROS Noetic

Slam ToolBox version: (1.5.6-1focal.20210922.203113)

rviz version: 1.14.10

When running the roslaunch commands in "Basic TeleOp with 3D sensor use" I received this error when running "roslaunch arlobot_ros view_navigation.launch" from the Ubuntu Desktop:

rviz (rviz/rviz)

ROS_MASTER_URI=http://localhost:11311

all processes on machine have died, roslaunch will exit

Rviz did open, but there was no RPLidar scan displayed on the grid.

Suggestions on how to troubleshoot this issue with the Slam Toolbox?

Regards,
