To enable autonomous navigation, you have to allow the robots to sense the environment around to create its map and enable collision avoidance, In other words, sensor data input to any algorithm is important.
Now there are various sensor solutions serving for this purpose, for example, Sonar, Lidar, MMW, Vision and so on they serves different preference and it’s possible to sensor fusion with them in the real autonomous navigation. Free to think ROS2 navigation can consider more:
- general flexibility to smoothly use their output in different phase of autonomous navigation
- how to adapt their combination or sensor fusion well while engaging with ros2 navigation stack
- consideration to certain solution with upcoming trend or innovation to extend, for example, for vision based, it may not require to create map firstly to navigation in the future.
