So, reading your link (https://github.com/husarion/rosbot_webui), i realized i did not do the following. so, after these steps,
sudo apt install nginx
Then edit configuration file:
sudo nano /etc/nginx/sites-enabled/default
and change line:
sudo systemctl restart nginx
Then, i went to browser with device name address, the lidar makes noise but nothing is visible on the webgui but a dial for running robot (robot does not move), and nothing on the rviz window either)
After running, webui launch file, it prints this repeatidly,
astra_wrapper::AstraDriver::resolveDeviceURI(const string&) @ /tmp/binarydeb/ros-kinetic-astra-camera-0.2.2/src/astra_driver.cpp @ 741 : Invalid device number 1, there are 0 devices connected.
I must have installed the wrong drivers. How do i correct to the astra?
