Use Gmapping without a laser
I'm using ROS Melodic, Gazebo 9.7.0 on an Ubuntu 18.04.2 LTS.
I have to make a map with odometry only. I'm going to teleop the robot to move it around a closed room to make the map. After I have the map, I have to order the robot to move to a goal (the robot will move autonomously).
To make the map I will move the robot from wall to wall using a "snake" pattern but without hitting anything.
I had thought to use gmapping to store the map but it seems that it needs a laser and I can't use it. Any suggestion about how to store the map and where? Thanks.
What sensors do you have to work with?
I'm not going to use any sensor. I only have odometry data.
Ok, in that case talking about mapping isn't really a meaningful thing if you have no way to view your environment (camera, lidar, depth camera, sonar, radar, bump sensor)
I have to do a map using only odometry. I think I'm talking about mapping.
