  • Blower and rotary rake for debris herding
    Patent number: 8151410
    Abstract: A debris herding method and apparatus is described comprising a low power air blower and a tilted rotary rake. The air blower acts together with a tilted rotary rake to dislodge and impel the debris. A motor driven chassis transports the blower and the rotary rake across the lawn. The blower and rotary rake can be energetically powered, such as by a solar cell array mounted to the chassis. The present invention is directed to an energetically efficient device for moving debris on a surface, such as leaves on a lawn.

  • Autonomous blower for debris herding
    Patent number: 8074320
    Abstract: An autonomous blower is described that utilizes GPS signals for blowing ground debris from a clearable area to a target area. A controller coordinates motors that propel and steer the autonomous blower. A database created in a teaching mode defines clearable, target, and no-trespassing areas with respect to GPS coordinates. An algorithm in the controller computes a serpentine trajectory for the autonomous blower so that it traverses the clearable area while transporting ground debris to the target area.
