Patents by Inventor David L. Gollaher

David L. Gollaher has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6925679
    Abstract: An autonomous canister vacuum cleaner has a cleaning head module, a vacuum fan module separated from the cleaning module, and a hose assembly connecting the cleaning head module with the vacuum fan module. The vacuum fan module includes a controller that performs navigation and control functions for both the vacuum fan module and the cleaning head module. Alternatively, the controller may be separated from the vacuum fan module and the cleaning head module, and can be mobile. The vacuum fan module and the cleaning head module each include a drive mechanism for propulsion. The cleaning head module includes a cleaning brush assembly that can be motorized or air driven. The cleaning head module may also include a microcontroller that communicates with the controller.

  • Patent number: 6496755
    Abstract: An autonomous mobile robot system allocates mapping, localization, planning and control functions to at least one navigator robot and allocates task performance functions to one or more functional robots. The at least one navigator robot maps the work environment, localizes itself and the functional robots within the map, plans the tasks to be performed by the at least one functional robot, and controls and tracks the functional robot during task performance. The navigator robot performs substantially all calculations for mapping, localization, planning and control for both itself and the functional robots. In one implementation, the navigator robot remains stationary while controlling and moving the functional robot in order to simplify localization calculations. In one embodiment, the navigator robot is equipped with sensors and sensor processing hardware required for these tasks, while the functional robot is not equipped with sensors or hardware employed for these purposes.
