can the ros navigation stack be used without laser scanner
Hello, I have a simple ros robot, which has odometry, an imu, and robot_pose_ekf, and I am getting almost correct trajectories in rviz. I also wrote a simple python program that gets the current heading and makes the robot move in desired direction for a given distance.
Instead of laser scanner I would like to use a top to down looking camera, and with an aruco marker on the robot, I think I will be able to determine its exact position.
Is there any way I can use the navigation stack, so I can navigate the robot into a desired goalpoint, (like within a constrained environment like a 2x2m box, with no obstacles, and the aruco system giving x,y of the robot visually)
Best Regards. C.A.
