Abstract

Provided is a robot, including: a chassis; a set of wheels coupled to the chassis; at least one motor; at least one motor controller; a range finding system; a plurality of sensors; a processor; and a medium storing instructions that when executed by the processor effectuates operations including: measuring, with the range finding system, distances to surfaces opposite the range finding system as the robot moves relative to the surfaces; monitoring, with the processor, the distance measurements taken by the range finding system; discarding, with the processor, outlier distance measurements that reflect an interruption in otherwise steadily fitting distance measurements taken as the robot moves towards and away from surrounding obstacles; and determining, with the processor, a position of an obstacle by identifying a position of the range finding system immediately before and after encountering the obstacle, signified by the interruption detected in the distance measurements.
