Robotic Infiltration

Solved by : thewhiteh4t

  • We got a capture.bag file in this one
  • The challenge mentions ROS which leads to a utility called rosbag
  • rosbag can be used to play this bag file
  • Installation and tutorials are given in ros wiki : http://wiki.ros.org/Documentation
  • The challenge mentions rebuild plan for facility
  • after some poking around we saw rosbag comes with another utility known as rviz
  • rviz can be used for 3d visualization of bag files

Step 1 : Start roscore

Step 2 : Play bag file

$ rosbag play capture.bag

Step 3 : Launch rviz

$ rosrun rviz rviz
  • Now all we had to do was tweak things in rviz a little to improve visibility and eventually we spotted the flag

  • After some play and pause action we got the full flag
