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

Recording the screen in Linux OS is always a tedious task, as either the video/audio malfunctions or support may not be there. There is a tools called simple screen recorder for Linux.
Its a very simple tool that is recorded and processed in no time. For example, if you record an 1 hour video, the processing may take another 20 to 50 minutes. But this software does the “On the fly recording and processing”
This software has a straight forward interface and its incomparable to other softwares in the market.
  • Its faster than VLC
  • It never takes more amount of RAM like VLC do.
  • Its multithreaded, if you have more than one core, then the processing happens at all the cores.
  • it can do live streaming also, but it is under experimental setting.
  • it supports many different codecs.
Here is the simple screenshot.

A 42 minute video is recorded using this software and it takes just 42minute only. no extra time for processing. Please see the youtube video attached below.
