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
Printing the routing table for any protocol is quite a easier task if the data structure is known. You may read the post on "printing the routing table for AODV protocol" Now this post will let you know how to print the routing table when using DSDV protocol. As you know, the DSDV protocol is a table driven protocol in which each node maintains a Routing table for a given source to destination and the table gets updated periodically to maintain the routes. But AODV protocol is a on demand routing protocol that deals with Route Request, Route Reply for forming the routes. So printing the routing table takes a minor tweak. But the DSDV protocol handles the routing table as a data structure, here is the steps to do it. OS Used : Linux Mint 17 - 64 bit NS2 Used : ns-2.35 Files to be modified: dsdv.cc and dsdv.h Step 1: The folder where ns2 installed on my machine /home/pradeepkumar/ns-allinone-2.35/ns-2.35 Execute these commands to access the DSDV protocol $promp
