Abstract: Systems and methods for robotic mapping are disclosed. In some exemplary implementations, a robot can travel in an environment. From travelling in the environment, the robot can create a graph comprising a plurality of nodes, wherein each node corresponds to a scan taken by a sensor of the robot at a location in the environment. In some exemplary implementations, the robot can generate a map of the environment from the graph. In some cases, to facilitate map generation, the robot can constrain the graph to start and end at a substantially similar location. The robot can also perform scan matching on extended scan groups, determined from identifying overlap between scans, to further determine the location of features in a map.

Plain-Language Overview of Independent Claims:

• Claim 1 (Method Claim): This claim describes a method for a robot to generate a map. It involves the robot traveling in an environment and creating a graph where each point (node) in the graph represents a sensor scan taken at a specific location. The method includes a step where the graph is adjusted so that its starting and ending points are essentially the same. It then performs "scan matching" on groups of scans (extended scan groups) to better understand the relationships between them. Based on this scan matching, the robot associates a possible range of locations with each point in the graph and determines how confident it is about these ranges. Finally, it optimizes the graph, using these confidence levels, to find the most likely location for each point and then uses this optimized graph to create the map.
• Claim 9 (System/Robot Claim): This claim describes a robot system designed for mapping. The robot includes a sensor that takes scans of an environment at various locations, creating nodes associated with these locations. It also has a "mapping and localization unit" which is configured to build a graph from these scans, identify groups of scans for extended scan matching, and then perform that scan matching.
• Claim 16 (Non-Transitory Computer-Readable Storage Apparatus Claim): This claim describes a non-transitory computer-readable storage apparatus (like a memory device) that contains instructions. When a processing unit executes these instructions, they cause a robot's sensor to generate scans at multiple locations (nodes), create a graph from these scans, identify extended scan groups from these scans, and then perform scan matching on those extended scan groups.
