Design a User-defined robot of your choice (or you can use the URDF file) and enable the LIDAR Scanner so that any obstacle placed on the path of the light scan will cut the light rays. Visualize the robot in the Gazebo workspace, and also show the demonstration in RViz. (NB: Gain knowledge on wiring URDF file and .launch file for enabling any user-defined robot to get launched in the gazebo platform.) SLAM : One of the most popular applications of ROS is SLAM(Simultaneous Localization and Mapping). The objective of the SLAM in mobile robotics is to construct and update the map of an unexplored environment with the help of the available sensors attached to the robot which will be used for exploring. URDF: Unified Robotics Description Format, URDF, is an XML specification used in academia and industry to model multibody systems such as robotic manipulator arms for manufacturing assembly lines and animatronic robots for amusement parks. URDF is especially popular with users of the Robo
IF you have a website that runs with an IP address and you decide to move it to a domain, then here is the clear step. Also this post will be helpful to you if you are running a same website by two different IP Address (One in campus and another outside the campus)
Prerequisites:
Your IP Address (Example): 172.16.1.10/site (Internal IP)
Your IP Address (Example): 28.45.34.101/site (External IP)
You want to move it to: example.com (instead of example.com/site)
Step 1:
Open the file /opt/lampstack-5.5.31-0/apache/conf/bitnami/bitnami.conf
In the above file, Change these lines (The bold lines are the changed ones)
<VirtualHost _default_:80>
DocumentRoot “/opt/lampstack-5.5.31-0/apache2/htdocs/site”
<Directory “/opt/lampstack-5.5.31-0/apache2/htdocs”>
Options Indexes FollowSymLinks
AllowOverride All
<IfVersion < 2.3 >
Order allow,deny
Allow from all
</IfVersion>
<IfVersion >= 2.3 >
Require all granted
</IfVersion>
</Directory>
to
<VirtualHost _default_:80>
DocumentRoot “/opt/lampstack-5.5.31-0/apache2/htdocs/site”
ServerName example.com
<Directory “/opt/lampstack-5.5.31-0/apache2/htdocs”>
Options Indexes FollowSymLinks
AllowOverride All
<IfVersion < 2.3 >
Order allow,deny
Allow from all
</IfVersion>
<IfVersion >= 2.3 >
Require all granted
</IfVersion>
</Directory>
Step 2: (Optional)
Open the file using sudo, /etc/hosts and include your IP with the domain name
GNU nano 2.2.6 File: /etc/hosts
127.0.0.1 localhost
127.0.1.1 administrator
172.16.1.10 example.com
28.45.34.101 example.com
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
Once done, restart apache server or the bitnami server by issuing this command
$/opt/lampstack-5.5.31-0] ./ctlscript restart
And now check example.com in the browser, you have done…..
If you manage apache server manually (Other than using bitnami lampstack), then you can edit the httpd-vhosts.conf file with the above steps.
