Abstract

An autonomous robot is maneuvered around a feature in an environment along a first trajectory. Data characterizing the first trajectory is stored as a trajectory landmark. The autonomous cleaning robot is maneuvered along a second trajectory. Data characterizing the second trajectory is compared to the trajectory landmark. Based on comparing the data characterizing the second trajectory to the trajectory landmark, it is determined that the first trajectory matches the second trajectory. A transform that aligns the first trajectory with the second trajectory is determined. The transform is applied to an estimate of a position of the autonomous cleaning robot as a correction of the estimate.
