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
XGRAPH in Ubuntu 20.04
There are two options to use either 32 bit or 64 bit OS, to find what OS instruction set your OS is Using, use the following command
$] uname -a
Linux pradeepkumar-Latitude-3410 5.8.0-36-generic #40~20.04.1-Ubuntu SMP Wed Jan 6 10:15:55 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
In the above output x86_64 indicates its 64 bit, else it may show i686 which indicates its a 32 bit OS
You can watch the complete instruction here on how to do?
$] gedit ~/.bashrc
include the following line in the .bashrc file (Copy the PAT H of xgraph and paste it in .bashrc)
include the following line in the .bashrc file (Copy the PAT H of xgraph and paste it in .bashrc)
alias xgraph=/home/pradeepkumar/XGraph4.38_linux64/bin/xgraph
After the above change is made, restart the computer and its set.
$] xgraph
A window will be popping up as shown below

How to plot a data file
#data.xg
1 3.2 4.3
#data.xg
1 3.2 4.3
2 4.5 6.9
3 9.8 11.9
4 10.2 17.6
5 7.8 22.2
To plot the above two curves, the following command can be used
$] xgraph data.xg
But only one curve will be printed, to print two curves use the following command
$] xgraph -c data.xg data.xg
You have selected to read column-oriented data in file 'data.xg'.
Please select the column numbers for x and y (first column = 1) ? 1 2
Using column 1 against 2.
You have selected to read column-oriented data in file 'data.xg'.
Please select the column numbers for x and y (first column = 1) ? 1 3
Using column 1 against 3.
10 points read.
Supply the values of two curves, 1 2 means X axis - 1 st column and Y axis - 2nd column
The output of the above command will be looking like this
