Abstract: A controlling method for an autonomous vehicle includes identifying a line track by the computing device via the camera set, and traveling the autonomous vehicle on a floor along the line track. When the autonomous vehicle is traveled relative to a wall, the line track is the wall-floor intersection, and the autonomous vehicle travels along the line track and parallel to the wall in a first predetermined distance determined by the computing device via the rangefinder and/or the camera set. When the autonomous vehicle travels where no walls are measured by the rangefinder and the camera set, the line track is a marking line on the floor, and the autonomous vehicle travels along the marking line in a second predetermined distance determined by the computing device via the camera set, and determining the travel path of the autonomous vehicle according to a preset map installed in the computing device.

Abstract: A motorized foldable bicycle assembly is foldably collapsible from a ridable elongated, segmented four sectioned frame arrangement. The frame consisting of a front wheel support frame, a front frame, a mid frame and a rear wheel support frame, with a set of electronically controlled motorized front and rear wheels spaced longitudinal alignment, apart one on each end of the four-sectioned elongated frame arrangement. The frame sections are foldable into an unridable configuration wherein the front wheel and a displaced rear wheel are arranged in an aligned, side-by-side adjacent, tandem configuration controllably guided by a steering column supported handlebar motor speed and direction control arrangement. A bicycle-supported tilt sensor actuator is in communication with a control computer and a circuit electronically connected to a bicycle handlebar switch, to permit operator controlled non-riding, self-powered, electric-motor-engaged movement of the tilted, partially foldably collapsed bicycle.

Abstract: A motorized foldable bicycle assembly arranged to be collapsible from an elongated four-sectioned segmented frame arrangement with a set of electronically controlled motorized front and rear wheels spaced longitudinally apart on the elongated frame arrangement. The front wheel and the rear wheel are arranged in an aligned, side-by-side adjacent configuration with a steering column supported handlebar arrangement correspondingly collapsed in a skewed or misaligned orientation in a space between the side-by-side wheels when folded up in an unridable configuration. The segmented frame arrangement generally forms a “M” configuration in the bicycle's folded and collapsed configuration.
