Abstract
A method for autonomous map generation by a robot comprising: instructing the robot to traverse a route within an environment in which the robot is deployed; while following the route, causing the robot to collect sensor data to identify features in the environment and to generate an initial map of areas in environment that have been traversed; upon completion of the route, autonomously generating a map of valid areas of the environment by moving throughout the environment while collecting sensor data; while autonomously generating the map, determining that a particular area is potentially invalid by detecting features that are previously unknown to the robot; generating and providing an electronic message to an operator of the robot comprising sensor data of the particular area and a prompt requesting information indicating whether the particular area is valid or invalid; upon receiving a response from the operator, continuing autonomously generating the map according to the response wherein if the particular area is valid, collecting sensor data from the particular area and, if the particular area is invalid, proceeding to an unmapped, valid area of the environment; determining t…
