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

By
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

Image
By
  1. Download NS2.35 from this link. http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.35/ns-allinone-2.35.tar.gz/download
  2. Copy the file to /home/yourhome (in my case it is, /home/pradeep/)
  3. Untar it using “tar zxvf ns-allione-2.35.tar.gz” (without quotes)
  4. “cd ns-allione-2.35/” (without quotes)
  5. “./install” (see the dot in the beginning)
  6. During the installation there may be a error in linkstate/ls.h, the location of ls.h is  “/home/pradeep/ns-allinone-2.35/ns-2.35/linkstate/ls.h”
  7. Open the file using gedit “gedit /home/pradeep/ns-allinone-2.35/ns-2.35/linkstate/ls.h”
  8. in line number 127, there will be a erase function, change it to this->erase and go to step 5.
  9. Once installation over, set the PATH and that’s it.
