  以降、同様に検査パスと移動パスを繰り返して、移動式検査装置本体３０によって前半の分割領域Ａ１の検査が完了する。

[0026] Then, when the inspection in the divided region A 1 of the front half is completed, the moving inspection device body 30 is turned 180° (pivotal turn) by rotating the right and left wheels 32 forward and backward,
そして、前半の分割領域Ａ１の検査が完了したところで、左右の２つの車輪３２を正逆回転させて移動式検査装置本体３０を１８０°旋回（超信地旋回）させ、

so that the flaw detection heads 44 are directed to a side edge A 2 a (opposite side to the side edge Ala) of the divided region A 2 facing the above-described center line (straight line).
探傷ヘッド４４を前述の中心線（直線）と対向する分割領域Ａ２の側縁Ａ２ａ（側縁Ａ１ａと反対側）側に向かせる。

[0020] Three wheels 16 to 18 are each provided on the left and right sides on the lower side of foot placing table 12 .
【００１２】
  足載置台１２の下側には、左右に３個ずつの車輪１６－１８が設けられる。

Each of wheels 16 to 18 has a steering function for changing the movement direction. Foremost wheel 16 has a locking function for restricting movement.
各車輪１６－１８は、移動方向を転換する転舵機能を有する。最前の車輪１６は、移動を規制するロック機能を備える。

Caring device 1 is capable of not only moving and changing the direction in the front-rear direction, but also laterally moving (moving in the true lateral direction) and spin turn (revolving on the spot) by the steering function of six wheels 16 to 18 .
介助装置１は、６個の車輪１６－１８の転舵機能により、前後方向の移動および方向転換だけでなく、横移動（真横への移動）や超信地旋回（その場旋回）が可能となっている。

Accordingly, the excavator 100 can perform neutral turn (i.e., a spin turn) by the lower traveling body 1 and change the orientation of the upper turning body 3 in the left direction so that the excavator 100 can front-face the target work surface.
これにより、ショベル１００は、下部走行体１による超信地旋回（即ち、スピンターン）を行い、上部旋回体３の向きを左方向に変化させて、目標施工面に正対させることができる。

US2021339993(PANASONIC IP MAN CO LTD [JP])
Thus, the carrier 1 according to this embodiment may travel forward and backward and turn to the right and to the left (e.g., may make a pivot turn and a spin turn).
したがって、本実施形態に係る搬送装置１は、前進、後進、左右方向への旋回（信地旋回及び超信地旋回を含む）を行うことができる。

 

Pivot turn, Wikipedia

In dance, a pivot turn (or simply pivot) is a general classification for dance turns in which the performer's body rotates about its vertical axis without traveling. The performer may be supported by one or both feet, which swivel in place during the pivot turn.[1] In some dance genres, a pivot on both feet is called a twist turn. Pivot turns are commonly named as such in ballroom dancing, folk dancing and ethnic dances. In many other dance genres, pivot turns are known by specific names and typically are not referred to as pivots. For example, in ballet, a pirouette is a type of pivot turn on one foot.
