Abstract: Systems and methods for detecting floor from noisy depth measurements for robots are disclosed herein. According to at least one non-limiting exemplary embodiment, a height map may be produced based on one or more depth measurements from a sensor of a robot. The height map may be utilized to determine surface normal vectors which may be further utilized by the robot to determine if regions of the height map are floor.

Abstract: Systems and methods for robotic detection of escalators are disclosed herein. According to at least one non-limiting exemplary embodiment, a robot may navigate a learned route and utilize one or more methods of detecting an escalator using data from its sensors. The robot may subsequently avoid the area comprising the escalator.

Abstract: Systems, apparatuses, and methods for calibrating LiDAR sensors of a robot using intersecting LiDAR sensors are disclosed herein. According to at least one non-limiting exemplary embodiment, a robot may calibrate a calibration LiDAR based on a determined pose of the calibration LiDAR, wherein the pose is determined based on a measurement error between the calibration LiDAR and an intersecting reference LiDAR.
