    摘要: A navigation and control system including one or more position sensors configured to generate position signals indicative of the location and heading of a vehicle. The system includes one or more operation control mechanisms having inputs and producing outputs which control an operation of the vehicle and includes a self-contained autonomous controller disposed remote from the operation control mechanisms. The autonomous controller includes a processor configured to receive the position signals from the position sensors and to generate operation control signals defining an updated travel path for the vehicle, and a programmable interface providing communication among the position sensors, the operation control mechanisms, and the processor. The programmable interface is configured to normalize inputs to the processor from the position sensors and to generate compatible operation control signals applied as the inputs to the operation control mechanisms, whereby the self-contained autonomous controller is configurable for operation with a variety of different sensors and different operation control mechanisms.

    摘要: A cleaning system includes a chassis supporting a propulsion system for propelling the cleaning system across a surface. At least one sensor of a first type is coupled to the chassis, and a surface engagement mechanism is configured to maintain the cleaning system coupled to the surface as the propulsion system propels the cleaning system across the surface. A cleaning device is coupled to the chassis and configured to abrade the fouling from the surface, and a controller coupled to the chassis and in signal communication with the propulsion system and the first sensor. The controller is configured to receive a signal from the at least one sensor of the first type and control the propulsion system in response to the signal.

    摘要: The invention is related to methods and apparatus that use a visual sensor and dead reckoning sensors to process Simultaneous Localization and Mapping (SLAM). These techniques can be used in robot navigation. Advantageously, such visual techniques can be used to autonomously generate and update a map. Unlike with laser rangefinders, the visual techniques are economically practical in a wide range of applications and can be used in relatively dynamic environments, such as environments in which people move. One embodiment further advantageously uses multiple particles to maintain multiple hypotheses with respect to localization and mapping. Further advantageously, one embodiment maintains the particles in a relatively computationally-efficient manner, thereby permitting the SLAM processes to be performed in software using relatively inexpensive microprocessor-based computer systems.
