2016-10-23 12:20:16 -0500 | asked a question | ROS move_base costmap not connected error I'm using ROS indigo running on 64bit Ubuntu 14.04 LTS. In the project, the nodes and visualisation (Rviz) seems to be functional when I launch the launch file I written. Here are the sensors used in the the project, which is a modified electric scooter:
When I start moving the scooter using the joystick, the scooter will move physically, but in Rviz, the object detected by the lidar moves to the scooter, instead of the scooter moving in the map. When I did roswtf, it shows that the robot footprint is disconnected, though the rqt graph shows otherwise. Please advise on the possible ways that I can undertake to debug this issue. Here are the node connections. For the navigation stack, I'm using the Teb local planner instead of the default planner. A screenshot of the tf tree: |
