PROBLEM TO BE SOLVED: To provide a fabricator reducing the need for human labor during manufacture and more fully automating the manufacture and assembly processes.SOLUTION: A fabrication system includes a tool-head 706 for manufacturing, a first manipulator 702 and a second manipulator 704. The first manipulator supports and manipulates an item 710, and is configured to provide six-axes of movement for positioning of the item relative the tool-head. The second manipulator carries a component 712 and orients the component at a select orientation relative to the item supported on the first manipulator. The tool-head is configured to add material to at least one of the item and the component. The first and second manipulators provide at least six axes of fabrication for the tool-head.

PROBLEM TO BE SOLVED: To provide an autonomous cleaning device capable of optimizing the cleaning capacity and efficiency of a cleaning mechanism. SOLUTION: The autonomous cleaning robot includes a chassis, a driving system mounted to the chassis to move the autonomous cleaning robot, and a cleaning head mounted to the chassis to clean a floor surface. The cleaning head includes a deck mounted to the chassis so as to be vertically pivotable with respect to the floor surface; a brush assembly mounted to the deck; and a deck adjusting assembly for pivoting the deck according to the torque change of the brush assembly. The deck adjusting assembly includes a pulley mounted to the deck side, and a pulley cord with one end fixed to the chassis side and with the other end fixed to the pulley.

Abstract:
PROBLEM TO BE SOLVED: To provide an autonomous cleaning device which instantly detects collision of debris to be cleaned on a floor and can control its operation mode in response to the detected debris, moving pattern and actions, so that the device is operated toward a dirtier area. SOLUTION: By a piezoelectric debris sensor responding to the collision of the debris and a related signal processor, an autonomous or nonautonomous cleaning device detects presence of the debris, responds and allows selections of action modes like spot coverage, action conditions and moving patterns. Two or more sensor channels can be used to enable detection or generation of a difference in right/left debris signals and, therefore, the autonomous device can be guided in the direction of the debris. In addition, by locating the debris sensor at a position where the debris swept up by a brush assembly collides, the collision of the debris becomes more properly detected.

Abstract:
PROBLEM TO BE SOLVED: To solve a problem of prior art which depends on a complicated system such as a marker or a beacon, and in which cleaning coverage is limited to a simple rectangle room, and using pseudo deterministic control algorithm leaves some space areas uncleaned. SOLUTION: A control system for a mobile robot is provided to effectively cover a given area by operating in a plurality of modes, including an obstacle following mode and a random bounce mode.
