Robotic Infiltration Writeup

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
