    摘要： A wheeled platform 100 is disclosed, which is characterized by high mobility and reliability, and which can be used in a wide range of applications including transport and robotic devices. The wheeled platform 100 has fore and aft body portions 130, 132, each body portion 130, 132 having first and second sides 106, 108. Overlapping wheels 112, 114, 116, 118 are rotatably attached to the first side 106 and overlapping wheels 120, 122, 124, 126 are rotatably attached to the second side 108. The fore body portion 130 can be connected to the aft body portion 132 via an articulation element 133.

    摘要： Method and apparatus for controlling the position of a sheet member (e.g., fabric) slidingly supported on a work surface, utilizing a drive train consisting of one or more drive wheels frictionally engaging a spherical ball captively supported within a housing. The drive wheels are preferrably located in spaced, mutually orthogonal relation proximate the great circle of the spherical ball. The spherical ball rests on and frictionally engages the fabric-to-be-positioned. Rotation of one of the drive wheels causes the spherical ball to rotate which, in turn, moves the fabric in a direction dependent on the location and orientation of said one drive wheel. The inventor can be implemented as an active feedback system utilizing the above-described apparatus together with position detectors and a controller.

    摘要： A propulsion system for use in a fluid, the system utilizing at least one foil which is both oscillated at a frequency f with an amplitude a in a direction substantially transverse to the propulsion direction and flapped or pitched about a pivot point to change the foil pitch angle to the selected direction of motion with a smooth periodic motion. Parameters of the system including Strouhal number, angle of attack, ratio of the distance to the foil pivot point from the leading edge of the foil to the chord length, the ratio of the amplitude of oscillation to the foil chord width and the phase angle between heave and pitch are all selected so as to optimize the drive efficiency of the foil system.
