    • Provided are: an automotive movable body capable of moving to an entire area surrounded by a wall excluding an area where an obstacle exists no matter what shape an obstacle existing within the area has; a movable body control method; and a recording medium storing a computer program. An automotive movable body for which moving algorithm is specified moves toward an object detected at the time of start of moving and judges whether the distance to the object is shorter than a predetermined value or not. When it is judged that the distance is shorter than a predetermined value, the body moves a first distance along the object, then moves a second distance in a direction intersecting the segment connecting the position before moving with the position after moving, and then moves toward the position where moving of the second distance is started after turning around at approximately 180°.
    • 提供:一种汽车移动体,其能够移动到除了障碍物存在的区域之外的围墙围绕的整个区域,无论存在于该区域内的障碍物的形状如何; 一种移动体控制方法; 以及存储计算机程序的记录介质。 指定运动算法的汽车移动体朝着在移动开始时检测到的物体移动,并且判断到物体的距离是否短于预定值。 当判断出距离短于预定值时,身体沿着物体移动第一距离,然后在移动之后的位置与移动之后的位置相交的方向上移动第二距离,然后向着 第二距离移动的位置在大约180°转动之后开始。

    • A driving circuit of a transmitting apparatus drives a piezoelectric element in a frequency band different from a resonance frequency at which a vibration system including the piezoelectric element resonates the most strongly. A driving circuit of a sound sensor drives the piezoelectric element for transmitting or receiving an acoustic wave in a frequency band different from a resonance frequency at which a vibration system including the piezoelectric element resonates the most strongly. Such a transmitting apparatus is mounted as a transmitting apparatus of a sound sensor to thereby realize the sound sensor with a small measurement error. The sound sensor is adopted for traveling control and steering control of an autonomous traveling vehicle to thereby enable an autonomous traveling vehicle capable of stopping in the vicinity of an obstacle to be realized.
