Questions tagged [slam]

This tag is for code related to SLAM (Simultaneous Localization and Mapping (SLAM) which is the computational problem, often related to robotics and/or drones, of constructing or updating a map of an unknown environment while simultaneously keeping track of an agent's location within it.

The following definition from Wikipedia:

In robotic mapping, simultaneous localization and mapping (SLAM) is the computational problem of constructing or updating a map of an unknown environment while simultaneously keeping track of an agent's location within it. While this initially appears to be a chicken-and-egg problem there are several algorithms known for solving it, at least approximately, in tractable time for certain environments. Popular approximate solution methods include the particle filter and extended Kalman filter.

ROS: Gmapping & Lidar (YDLIDAR) - seeing through walls and obstacles?

Lidar is working well, by which I mean that LaserScan looks very good in Rviz, but when trying to map with GMapping, the map is drawing walls, but it's also marking free space beyond the walls and other obstacles. I have tweaked the maxRange and…
