    Abstract: An autonomous mobile device (AMD) uses sensors to explore a physical space and determine the locations of obstacles. Simultaneous localization and mapping (SLAM) techniques are used to process images from cameras to determine location and trajectory of the device. As the AMD moves and explores to generate an occupancy map, errors in the localization accrue. The occupancy map is processed to determine a graph that is based on, for a given point in physical space, a distance, relative direction, and a characteristic of a closest obstacle. A first graph based on a global occupancy map may be compared to a second graph based on a local occupancy map to determine a displacement between the local occupancy map and the global occupancy map. To facilitate loop closure, the AMD may navigate to a point along the first graph, where a loop closure process may be performed.

    Abstract: A service vehicle can have a service vehicle battery that can provide energy to, and/or receive energy from, a separate machine that is normally configured to operate based on energy provided by a battery of the machine. If a machine becomes unable to operate using the battery of the machine, the service vehicle can travel to the machine and use an energy transfer arm to transfer energy to the machine. In some situations, the service vehicle and the machine can travel together in a convoy formation, for instance to a maintenance station, while the service vehicle provides the machine with energy for driving operations of the machine.

    Abstract: A method and a system to present samples of products to customers by transporting the samples to the customer's location with an autonomous vehicle. The sample can be a product, a component of a product, a material or a device to gather information in defining the product. The autonomous vehicle is adapted for off road travel and may enter buildings, it can be carried to a nearby location by a street adapted vehicle. Information may be transmitted electronically but physical presence is essential. The customer or the customer's agent receives a presentation of the product definer and a selection of a final product is made. In other cases the autonomous vehicle delivery separate or installed technical equipment to examine the presentation location and assist in the final product selection. For example, photographs from multiple locations can measure a room for installation of carpets or draperies, etc.
