I am trying to read in messages from the turtlebot's lidar in the form of LaserScan messages and use those to stop the turtlebot from moving forwards when there is an obstacle. However, when I read the data in what I understand to be the forward direction it doesn't come back with a result I expect i.e. the the range distance is large even when the turtlebot is directly next to an obstacle.
