  • Patent number: 8800695
    Abstract: A robotic vehicle (10,100,150A,150B150C,160,1000,1000A,1000B,1000C) includes a chassis (20,106,152,162) having front and rear ends (20A,152A,20B,152B) and supported on right and left driven tracks (34,44,108,165). Right and left elongated flippers (50,60,102,154,164) are disposed on corresponding sides of the chassis and operable to pivot. A linkage (70,156,166) connects a payload deck assembly (D1,D2,D3,80,158,168,806), configured to support a removable functional payload, to the chassis. The linkage has a first end (70A) rotatably connected to the chassis at a first pivot (71), and a second end (70B) rotatably connected to the deck at a second pivot (73). Both of the first and second pivots include independently controllable pivot drivers (72,74) operable to rotatably position their corresponding pivots (71,73) to control both fore-aft position and pitch orientation of the payload deck (D1,D2,D3,80,158,168,806) with respect to the chassis (20,106,152,162).

  • Publication number: 20140215735
    Abstract: A surface treatment robot includes a chassis having forward and rear ends and a drive system carried by the chassis. The drive system includes right and left driven wheels and is configured to maneuver the robot over a cleaning surface. The robot includes a vacuum assembly, a collection volume, a supply volume, an applicator, and a wetting element, each carried by the chassis. The wetting element engages the cleaning surface to distribute a cleaning liquid applied to the surface by the applicator. The wetting element distributes the cleaning liquid along at least a portion of the cleaning surface when the robot is driven in a forward direction. The wetting element is arranged substantially forward of a transverse axis defined by the right and left driven wheels, and the wetting element slidably supports at least about ten percent of the mass of the robot above the cleaning surface.

  • Publication number: 20140222251
    Abstract: A method of confining a robot in a work space includes providing a portable barrier signal transmitting device including a primary emitter emitting a confinement beam primarily along an axis defining a directed barrier. A mobile robot including a detector, a drive motor and a control unit controlling the drive motor is caused to avoid the directed barrier upon detection by the detector on the robot. The detector on the robot has an omnidirectional field of view parallel to the plane of movement of the robot. The detector receives confinement light beams substantially in a plane at the height of the field of view while blocking or rejecting confinement light beams substantially above or substantially below the plane at the height of the field of view.

  • Patent number: 8798840
    Abstract: A system and method for mapping parameter data acquired by a robot mapping system is disclosed. Parameter data characterizing the environment is collected while the robot localizes itself within the environment using landmarks. Parameter data is recorded in a plurality of local grids, i.e., sub-maps associated with the robot position and orientation when the data was collected. The robot is configured to generate new grids or reuse existing grids depending on the robot's current pose, the pose associated with other grids, and the uncertainty of these relative pose estimates. The pose estimates associated with the grids are updated over time as the robot refines its estimates of the locations of landmarks from which determines its pose in the environment. Occupancy maps or other global parameter maps may be generated by rendering local grids into a comprehensive map indicating the parameter data in a global reference frame extending the dimensions of the environment.

    Abstract: A robot obstacle detection system including a robot housing which navigates with respect to a surface and a sensor subsystem aimed at the surface for detecting the surface. The sensor subsystem includes an emitter which emits a signal having a field of emission and a photon detector having a field of view which intersects the field of emission at a region. The subsystem detects the presence of an object proximate the mobile robot and determines a value of a signal corresponding to the object. It compares the value to a predetermined value, moves the mobile robot in response to the comparison, and updates the predetermined value upon the occurrence of an event.
