Abstract: A multi-plane scanner support system includes a bracket and a mirror block. The bracket is configured to be secured in a fixed orientation with respect to a scanner. And the mirror block is arranged to receive a scanning signal from the scanner and to reflect the scanning signal into a plurality of directions to create multiple scanning planes. The scanner can be a laser scanner. The scanner and multi-plane scanner support system can be attached to a material transport vehicle, for example, to provide safety functions. The vehicle can be manned or unmanned.

Abstract: Provided is a tugger attachment apparatus configured for use with a pallet transport. The pallet transport has a front drive portion and a rear load portion having a pair of forks. The tugger attachment includes a body, a fork coupling member at a bottom side of the body that is configured to secure the body to the forks, and a hitch supported by the body. A linkage can be provided that opens and closes the hitch in response to raising and lowering of the forks of the pallet transport.

Abstract: A low-profile signal device is provided having a plurality of light emitters disposed on at least one support member, the plurality of light emitters configured to emit light in a plurality of colors that indicate one or more predefined conditions; a housing substantially enclosing the at least one support member; a signal interface coupled to the plurality of light emitters and configured to selectively activate light emitters from the plurality of light emitters in response to a received control signal.

Abstract: In accordance with aspects of the present invention, a service robot and methods for controlling such a robot are provided. In particular, the robot is configured to sense the presence of a person and to take a next action in response to sensing the presence of the person. As examples, the robot could leave the area, await commands from the person, or enter an idle or sleep state or mode until the person leaves.

Abstract: A system is provided that includes at least one manager and one or more robots configured to communicate wirelessly. The manager can include certain functions that generate data, instructions, or both used by one or more robots. The manager can also facilitate communications among several robots, or robots could also be configured to communicate directly.

Abstract: In accordance with aspects of the present invention, a service robot, such as a robotic cleaner, can be configured to more effectively service an environment. The service robot can include one or more sensors that sense its location, the location of objects, or both, and can also include noise reduction elements. The service robot can determine that it is under a “furnishing” and implement a different servicing pattern.

Abstract: Robots and methods implemented therein implement an active repurposing of temporal-spatial information. A robot can be configured to analyze the information to improve the effectiveness and efficiency of the primary service function that generated the information originally. A robot can be configured to use the information to create a three dimensional (3D) model of the facility, which can be used for a number of functions such as creating virtual tours of the environment, or porting the environment into video games. A robot can be configured to use the information to recognize and classify objects in the facility so that the ensuing catalog can be used to locate selected objects later, or to provide a global catalog of all items, such as is needed for insurance documentation of facility effects.

Abstract: Mapping, localization, and navigation systems for use with a mobile unit are provided that use a sensor model with adjustable parameters. The system includes range sensors configured to collect range data and a data storage system having stored therein an evidence grid representing an environment and a sensor model comprising adjustable parameters representing inaccuracies of the range sensors. A grid engine adjusts the adjustable parameters based on received range data from the range sensors. A navigation module can direct the mobile unit though the environment using the evidence grid, received range data, and adjustable parameters. The grid engine can also locate the mobile unit within the environment by using the adjusted sensor model parameters to compare the received range data against the evidence grid.

Abstract: A method of generating an evidence grid representing an environment comprises the steps of collecting a set of stereo images at multiple locations within the environment using stereo sensors, and processing the set of stereo images to determine occupancy and distance data associated with each point in space represented in the set of stereo images; applying a sensor model to each point in space to determine a probability of occupancy of each voxel representing each point in space; and generating an evidence grid of the environment by combining the probabilities for each voxel.
