Simulation of URDF, Gazebo and Rviz | ROS Noetic Tutorial 8

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

Recompiling Linux Kernel

How to add a new kernel to linux OS and compile it and use it, the following points discusses that.
Step 1: Download a new kernel from kernel.org (recent version is 2.6.33)
Step 2: you may get the file either as a .tar.bz2 file  or .tar.gz file
Step 3: untar the file in the /usr/src directory (for installing you need to be a root user)
if it is a bz2 file, then execute tar jxvf filename.tar.bz2 –C /usr/src
if it is a gz file, then execute tar zxvf filename.tar.gz –C /usr/src
Step 4: go to the folder /usr/src using the command cd /usr/src

Step 5: Execute the following 
    Execute any one of the following command
  • make config (for text mode)
  • make menuconfig
  • make xconfig (for X window)
  • make gconfig (this command is preferred)
Step 6: make  (will take atleast 30 minutes to complete, be patient)
Step 7: make modules
Step 8: make modules_install
Step 9: make install
Once done, reboot the system, your grub loader is updated with one more kernel.
(NB: in the previous flavors of linux, the following are the set of commands
  • make xconfig
  • make dep
  • make
  • make bzImage
  • make modules
  • make modules_install
  • make install    )
