Contour following guidance
Contour following guidance, also called contour navigation, is an AGV navigation method that steers by matching LiDAR scans against a stored map instead of floor-installed guide paths.
Contour matching navigation
Contour matching navigation is a natural navigation method for automated guided vehicles that localizes by matching scanned wall, rack, and machinery profiles against a map.
Factor graphs
A factor graph is a bipartite probabilistic graphical model whose variable nodes and factor nodes define a global function, serving as the standard back end for robot SLAM.
Painted line guidance
Painted line guidance is a navigation method in which a mobile robot or AGV steers by tracking a painted line on the floor, detected by onboard optical or camera sensors.
Polarized light guidance
Polarized light guidance uses light's polarization rather than its intensity as a navigation cue, from desert ants' skylight compass to polarized beacons guiding industrial driverless vehicles.
QR code navigation
QR code navigation is a robot navigation method where floor QR codes serve as fixed references, letting a camera-equipped robot correct dead-reckoning errors between codes.
Wi-Fi fingerprinting
Wi-Fi fingerprinting is an indoor positioning technique that estimates a device's location by matching measured Wi-Fi signal strengths against a pre-built database collected at known positions.
