【発明の属する技術分野】
本発明は、走行機能を有し自走しながら清掃等の作業を行なう移動作業ロボットに関するものである。
【0002】
【従来の技術】
従来、作業機器に走行操舵手段やセンサ類および移動制御手段を付加して、2次電池を搭載してコードレスで自動的に作業を行う各種の移動作業ロボットが開発されている。自走式掃除機を例にとると、作業機器である清掃部分の機能として本体底部に吸込みノズルやブラシなどを備え、移動機能として走行および操舵手段と、移動時に障害物を検知する障害物検知手段とを備え、領域内を障害物を回避しながら自律移動して領域全体を清掃するものである。
【0003】
具体例として、ゴミ検知手段と音響手段、および設定ゴミ量以上を検知すると回転掃除走行を行う機能を設け、回転掃除中に音響手段からメロディ等の音を鳴らすことにより、使用者に、ゴミの多い場所を報知するとともに、故障等による回転動作ではないかとの誤解を与えないようにしているものがある(例えば、特許文献1参照)。また、本体情報を無線通信可能な情報携帯端末に発信するものもある(例えば、特許文献2参照)。

【発明が解決しようとする課題】
しかしながら、前記従来の構成では、移動作業の開始から終了まで自動で行うが、途中、種々の異常状態が発生すれば、所定の移動経路をたどれない、あるいは、移動作業を中断しなければならないことになり、自動作業機器としての役割を果たすことができなくなる可能性があるという課題を有していた。当然ながら、上記の異常が発生しないよう開発、設計、製造されるものであるが、機器が使用される環境は多種多様であり、仮に環境を限定しても完全に異常を無くすことは不可能なので、異常が発生した場合の対応が望まれる。そこで例えば、異常状態を本体に視覚表示させたとすると、使用者は本体に近づいて確認しなければならない。
【0006】
また、前記従来例(特許文献1参照)の音響手段から発するメッセージは、ゴミの多い場所で回転動作を行いその間メロディ等の音を鳴らすというパターンに限られ、自動作業機器として支障をきたす可能性がある異常時に、音響手段を活用して使用者に異常を知らせることには言及していない。さらに、前記従来例(特許文献2参照)の情報携帯端末にて本体情報を確認できる場合、使用者が作業現場から遠く離れた別の場所に居れば、異常発生を知るのに有効な手段であるが、現場近辺にいる場合、かえって機器操作が必要となるものである。
【0007】
本発明は、前記従来の課題を解決するもので、移動作業ロボットが自律走行しながらの作業中に、使用者は音声の届く比較的遠くまでの範囲において、本体に近づいたり情報携帯端末等の別途の機器操作をすることなしに、他の活動をしながらでも音声により本体の異常を把握することができ、かつ、この情報を記録しておいて、使用者が後に自在に確認でき、保守管理でき得る移動作業ロボットを提供することを目的としている。

【0018】
【実施例】
(実施例1)
以下、本発明の実施例を自走式掃除機に応用した場合を例にとって、図1〜5に基づいて説明する。
【0019】
まず図1にて本体構成を説明する。図1は、本発明の第1の実施例における移動作業ロボット(自走式掃除機)全体構成の内部透視斜視図である。1は清掃領域内を移動しながら清掃を行なう自走式掃除機の本体で、床面上を矢印2の方向に前進して移動する。
【0020】
3、4は本体1の左右に配した駆動モータで、それぞれの出力軸は左右の減速機5、6を介して本体1の両側部に配した左右の走行輪7、8を回転駆動する。走行輪7、8と方向自在なフリーキャスターからなる従輪(図示せず)により、本体1の重量を支持している。3‘、4‘はロータリーエンコーダ等からなる回転検出手段で、各々、左駆動モータ3と右駆動モータ4の軸回転数を検出し、減速機5、6の減速比を乗じることにより走行輪7、8の回転数とできる。左駆動モータ3と右駆動モータ4を、所望の回転数になるよう、回転検出手段3‘、4‘の出力を検出しながら制御するが、これらを独立に回転駆動制御することにより、本体1を矢印2の方向に移動させることはもとより、左駆動モータ3と右駆動モータ4の回転数を異ならせることにより本体を右旋回あるいは左旋回させることができ、走行手段および操舵手段の機能を有している。9は各種入力に応じて左右の駆動モータ3,4を回転制御し、本体1の移動制御を行なう移動制御手段で、マイクロコンピュータおよびその他制御回路からなる。
【0021】
10,11は本体1の外周に沿って設けた測距手段で、本体1の前方、側方および後方の壁および障害物までの距離を測定する。本実施例では10を相対的に視野角が広い超音波センサと、11を相対的に安価で小型軽量の光センサで構成している。29は接触検出手段で、本体1の周囲に内側への可動自在に配備され外側表面を緩衝材で構成した可動体(可動バンパー)の、壁や障害物への接触を、マイクロスイッチあるいは圧力センサで検出する。21は本体1の方向および位置を計測する位置認識手段で、回転検出手段3‘、4‘から移動軌跡を演算する軌跡計測手段からなるが、本体の方向を計測するジャイロなどの方向計測手段を組み合わせてもよい。31はスピーカーからなる音声表示手段で、音声信号発生部32(後述)が発信する予め入力されているあるいは都度合成された音声信号を音声に変換して外界に発声する。28は入力部であり、詳細は後述する。
【0022】
12は本体1の前方下部に配され、床面を掃除する清掃ノズルで、清掃ノズル12の下面にはごみを吸引する吸込口が設けられ、この吸込口に臨むように回転ブラシなどからなるアジテータ13が清掃ノズル12内に設けられ、ファンモータで構成する電動送風機14を駆動することで真空圧を発生させ、清掃ノズル12にその真空圧を作用させて吸込口よりゴミを吸引する。
【0023】
前記アジテータ13はノズルモータ15により伝動ベルト16を介して回転駆動される。17は上記清掃ノズル12とファンモータ14の連通路途中に設けた吸引量検出手段で、透過型あるいは反射型の光学式センサにより、通過するゴミの有無を検出してゴミ数をカウントすると同時に、センサ受信信号の形によりゴミ種類を判別する。18は上記連通路の電動送風機14前に設けた集塵室で、サイクロン式分級タンクあるいは紙パック等のフィルタで構成され、吸引したゴミはここに貯められる。19は集塵室18に設けられた集塵量検出手段19で、集塵室18内部のゴミ嵩あるいは吸引動作中の圧力により集塵量を検出する。
【0024】
以上、清掃ノズル12、アジテータ13、電動送風機14、ノズルモータ15、伝動ベルト16、吸引量検出手段17、集塵室18、集塵量検出手段19により清掃手段を構成している。なお、センサである吸引量検出手段17、集塵量検出手段19や、アジテータ13およびこれに付随するノズルモータ15、伝動ベルト16は必要に応じて設ければよい。
【0025】
20は鉛、ニッケル水素あるいはニッケルカドミウム蓄電池などからなる2次電池で、移動制御手段9を介して、本体1内の駆動モータ3,4、電動送風機14、ノズルモータ15、音声表示手段31等、必要部分に電力を供給する。
【0026】
次に、図2、図3はそれぞれ、異常発生時の、異常履歴表示時の入力部28詳細図である。37は電源スイッチで、2次電池20から移動制御手段9および入力部28自体への電力供給をON/OFFする。36は表示部であり液晶画面で構成され、所定箇所を指先等で触れることにより各種入力が行えるタッチパネル様式となっている。33は日付と時刻を刻む時計であり、電源スイッチ37をOFFすると表示は消えるが、2次電池20とは別途設けた電池(例えばボタン電池:図示せず)により、時を刻む機能は常時継続する。30、30‘は点検済入力手段であり、本体に異常が発生した場合、使用者が点検作業を終えた後にこの入力を行うことにより、記憶手段38(詳細は後述)に点検済であることが入力日時をもって記録される。34は記録再生手段で、電源スイッチ37がONの間は図2の異常発生時に限らず常時入力可能状態となっており、入力すると図3の異常履歴表示画面になる。35は音声再生手段で、入力すると、異常履歴表示画面にて選択(例:図3の網掛け。方法詳細割愛)されている異常内容、発生日時、および対応する点検すべき内容(点検済の場合は点検済入力日時)が音声でも再生表示される。なお、電源ON待機時や正常運転時に表示部36に表示されるべきスタート、ストップ、運転モード選択等の各種入力については、本発明の請求範囲と直接関係ないので、詳細な説明は割愛する。
【0027】
次に、図4は本実施例のシステム構成を示す制御ブロック図である。移動制御手段9は、2次電池20からの電源をもとに、測距手段10、11、位置認識手段21、吸引量検出手段17、集塵量検出手段19、回転検出手段3‘、4‘、接触検出手段29、入力部28からの入力に応じて、左駆動モータ3および右駆動モータ4と、電動送風機14およびノズルモータ15、音声表示手段31への出力を制御する。
【0028】
また、移動制御手段9は、次述の各手段、各モード等を有する。測距手段10、11からの入力に基づいて、壁から一定距離(距離0も含む)で本体1を移動させる壁沿い移動手段22、清掃領域の内側部分を塗りつぶすように移動させる内部移動手段23、清掃手段を稼動しながら本体1を移動させる清掃モード24、清掃手段を停止して本体1を移動させる移動モード25を有する。
【0029】
また、2次電池20の電圧より電池の残量を検出する電池残量検出手段26、音声表示手段31から発生する音声信号の発信元である音声信号発生部32、本体1に生じた異常内容や点検済入力手段30からの入力と時計33から所定のタイミングで出力される日付や時刻等を記録する記憶手段38である。
【0030】
なお、記憶手段38に記録された内容は、電源スイッチをOFF(移動制御手段9への電力供給を停止)しても、2次電池20とは別途設けた電池(例えばボタン電池:図示せず)により、消去されない。
【0031】
以上の構成による動作を、作業領域での一連動作例を示す図、図5を用いて説明する。まず、入力部28で(電源ONおよび)スタート入力が手動あるいは自動(タイマー設定等)で行われる。そして本体1は、清掃対象の床面A(清掃領域)上のスタート点Sから運転(清掃しながらの移動)を開始する。
【0032】
まず、破線矢印で示すように、壁沿い移動手段22により、壁および障害物40から所定距離(距離0を含む)でこれに沿って清掃領域A外周の移動を開始する。この間、清掃手段により壁際の清掃を行う。壁沿いに一周して再びスタート点Sに戻ってくると、位置認識手段21により壁沿いを一周したことおよび清掃領域Aを検知、認識し、測距手段10、11で壁面を確認しながら、位置認識手段21の認識に基づいて、次の移動に備えて本体1の位置および方向を修正したあと一旦停止する。
【0033】
次に、内部移動手段23により、外周より内側部分の清掃移動を開始する。内部領域の清掃移動は、実線矢印で示すように、直進とターンを繰り返してほぼ清掃ノズル12幅ずつ領域を塗りつぶすように移動を進め、中央の障害物41を測距手段10、11で検出して回避しながら領域の清掃を進める移動である。回避動作は、所定の内部領域移動経路に戻るまで障害物41に沿って移動するものとし、障害物41との距離は、前記壁沿い移動と同様であるとする。移動制御手段9は、位置認識手段21および測距手段10、11により、清掃領域Aのスタート点Sとは反対側の壁面まで清掃が到達したと認識すると、清掃手段の稼動を停止する。最後に本体1は、移動モード25で壁沿い移動22にて外周壁沿いにスタート点Sまで戻る。このあと自動的にスタート入力の待機状態となる。待機状態では、2次電池20の残量を少しでも節約するため、2次電池20の移動制御手段9への電力供給を遮断する。
【0034】
次に、本件の特長である異常検出と異常内容・点検内容の音声表示、異常履歴の記録、点検済入力等の動作について、再び図2および図3と、図6〜図8に基づいて説明する。
【0035】
図6は異常検出時の音声表示のフローチャート、図7は記憶手段に保存されていく異常履歴のイメージ図、図8は予め所定箇所に記録されている検出した異常内容とメッセージ等の対応を示す図である。以下、異常内容として、2次電池20の残量が少なくなった、すなわち所定量を下回ったことを電池残量検出手段26が検出した場合を例にとり、図6のフローに沿って説明する。
【0036】
異常を検出(STEP1)すると、異常内容が時計33で計時している発生日時とともに、記憶手段38に書き込まれれる(a)。そして、図8で示す対応に従い、移動は継続しながら、清掃手段を停止(b)する。次に、音声表示手段31が異常内容を示すメッセージとして「電池の残りが少ないです」と表示(STEP2)し、さらに、点検内容を示すメッセージとして「充電して下さいあるいは電池を交換して下さい」と表示(STEP3)する。使用者がこれらのメッセージに従い、この後すぐ、点検作業として、図2で示す一旦停止入力を行って本体1の移動を一旦停止した上で電池交換を行い(STEP4)、点検作業終了後に点検済入力(STEP5)、すなわち点検完了ボタン30あるいは30‘に触れたとする。このとき記憶手段38には点検済入力がなされた日時が入力されることで点検済となったことが記録(c)される(図7左上)。点検済入力がされたことで清掃手段停止は解除(d)され、移動の一旦停止も解除すると、ほぼ異常発生前の本体1の状態、作業状況に戻すことができる。
【0037】
なお、後に発生する他の異常や点検入力についても上記同様、図7に示すようなイメージで履歴として保存されていく。ちなみに音声表示中およびその後の所定時間中、あるいは点検済入力がなされるまで、図2で示すように音声メッセージと同一の文言が表示部36に表示される。
【0038】
履歴を確認する方法は前述のとおりであるが、図3の状態で音声再生手段35を入力すると、音声表示手段31が次のようにメッセージを流す。「2002年9月30日に電池の残りが少ない異常が検出されました。2002年10月2日に異常が解消されました」。仮にこの案件が未点検であるとすると、メッセージの後半は「充電して下さいあるいは電池を交換して下さい」と表示する。
【0039】
上記については、異常内容の一例を示したものでありこれに限定するものではない。かつ、表示部36の文字表示、音声表示手段31の音声表示の、内容および方法についてもこれに限定するものではない。
【0040】
なお、音声表示あるいは表示部36の画面表示で、異常内容と点検内容(あるいは点検済入力)を両方表示するのが、丁寧で望ましいが、短文で簡潔に表示したい等、望まれる仕様に応じて、異常内容あるいは点検内容のどちらか一方の表示のみでもかまわない。
【0041】
また、音声発生部31の位置および個数は、図1に限定するものではなく、むしろ全方向に音声を発生させるほうが好ましい。
【0042】
また、内部移動手段23による移動パターンは図5に限定するものでなく、例えば、直進とランダム角度ターンの繰り返しでもよい。
【0043】
また、2次電池20の充電方法については特に限定するものではないが、大きくは2次電池20を取り出すか、本体1に内蔵したまま行うかで区別できる。いずれにしても、別途、充電器は必要である。自動充電を行うには、スタート点Sにランドマークとなるステーションを設置し、これに自動充電機能を設けることが考えられる。
【0044】
以上により、音声の届く範囲にいる使用者が、本体に近づいたり別途機器を操作することなしに、異常が生じたこと、そして異常の内容を音声により確認することができる。そして、音声表示の指示に従って使用者が点検作業を行い異常を解消でき得ることができる。さらに、点検済入力を行って、本体の移動制御を異常発生前に戻し得ることとできる。また、異常履歴を記憶手段に記録蓄積していき必要に応じて後に自在に確認できることで、保守管理が可能となる。
【0045】
【発明の効果】
以上のように、請求項1〜8記載の発明によれば、移動作業ロボットの運転中に、音声を聴くことのできる範囲にいる使用者が、本体に近づいたり別途機器を操作することなしに、他の活動をしながらでも音声により本体の異常を把握することができる。そして、音声表示の指示に従って使用者が点検作業を行い異常を解消でき得ることができる。さらに、点検済入力を行って、本体の移動制御を異常発生前に戻し得ることとできる。また、異常履歴を記憶手段に記録蓄積していき必要に応じて後に自在に確認できることで、保守管理を可能とすることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mobile work robot having a traveling function and performing work such as cleaning while traveling by itself.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, various types of mobile work robots have been developed in which a travel steering unit, sensors, and a movement control unit are added to work equipment, and a secondary battery is mounted to automatically perform work without cords. Taking a self-propelled vacuum cleaner as an example, a suction nozzle and a brush are provided at the bottom of the main unit as a function of the cleaning part, which is a working device, and traveling and steering means as a movement function, and obstacle detection that detects obstacles when moving And autonomously moving while avoiding obstacles in the area to clean the entire area.
[0003]
As a specific example, a dust detection unit and a sound unit, and a function of performing a rotary cleaning run when the amount of dust detected is equal to or more than a set dust amount is provided. There is a device that notifies a location where there is a large number of locations and does not give a misunderstanding that the operation is a rotation operation due to a failure or the like (for example, see Patent Document 1). There is also a device that transmits main body information to an information portable terminal capable of wireless communication (for example, see Patent Document 2).
[0004]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 2000-37333 [Patent Document 2]
JP 2000-342496 A
[Problems to be solved by the invention]
However, in the above-described conventional configuration, the moving operation is automatically performed from the start to the end of the moving operation. However, if various abnormal states occur on the way, the moving operation must not be followed or the moving operation must be interrupted. As a result, there is a problem that there is a possibility that it may not be possible to play a role as an automatic working device. Naturally, it is developed, designed, and manufactured so that the above abnormalities do not occur.However, the environment in which the equipment is used is diverse, and it is impossible to completely eliminate the abnormalities even if the environment is limited. Therefore, it is desired to take a countermeasure when an abnormality occurs. Thus, for example, if an abnormal state is visually displayed on the main body, the user must approach the main body to check.
[0006]
Further, the message issued from the acoustic means of the conventional example (see Patent Document 1) is limited to a pattern in which a rotating operation is performed in a place with a lot of dust and a sound such as a melody is sounded during the rotation operation, which may hinder an automatic working device. It does not mention using an acoustic means to notify the user of an abnormality in the event of an abnormality. Furthermore, when the information on the main body can be confirmed with the information portable terminal of the conventional example (see Patent Document 2), if the user is at another place far away from the work site, it is an effective means for knowing the occurrence of abnormality. However, if you are near the site, you need to operate the equipment.
[0007]
The present invention is to solve the above-mentioned conventional problems, and while the mobile work robot is working while autonomously traveling, the user can approach the main body or a portable information terminal or the like within a relatively far range where voice can reach. Without having to operate the equipment separately, it is possible to recognize abnormalities of the main unit by voice while performing other activities, and record this information so that the user can freely check it later for maintenance. The purpose is to provide a mobile work robot that can be managed.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned conventional problems, a mobile work robot according to the present invention includes: a traveling unit that moves a main body; a steering unit that changes a moving direction of the main body; a working unit that performs operations such as cleaning; Means for controlling the movement of the main body by controlling the steering means and the steering means; voice display means for displaying the details of the abnormality by voice when the body is abnormal; and storage means for recording the details of the abnormality.
[0009]
As a result, a user who can hear the sound can recognize the abnormality of the body by voice while performing other activities without approaching the mobile work robot body or operating the separate equipment. In addition, this information can be recorded and used later.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
The invention according to claim 1 controls traveling means for moving the main body, steering means for changing the moving direction of the main body, working means for performing work such as cleaning, and controlling the traveling means and the steering means. Movement control means for controlling the movement of the main body, voice display means for displaying the content of the abnormality by voice when the main body is abnormal, and storage means for recording the content of the abnormality, the user within the reach of the voice, It is possible to confirm the occurrence of the abnormality and the details of the abnormality by voice without approaching the main body or operating the device separately. Then, the contents of the abnormality can be recorded in the main body and can be used later.

[0030]
Note that the content recorded in the storage means 38 is a battery provided separately from the secondary battery 20 (for example, a button battery: not shown) even when the power switch is turned off (power supply to the movement control means 9 is stopped). ), It is not erased.
[0031]
The operation according to the above configuration will be described with reference to FIG. 5 showing a series of operation examples in the work area. First, a start input (power ON and) is input manually or automatically (such as setting a timer) in the input unit 28. Then, the main body 1 starts operation (moving while cleaning) from a start point S on the floor A (cleaning area) to be cleaned.
[0032]
First, as shown by the dashed arrow, the movement of the outer periphery of the cleaning area A is started along the wall and the obstacle 40 at a predetermined distance (including the distance 0) by the wall moving means 22. During this time, the wall is cleaned by the cleaning means. After making a round along the wall and returning to the start point S again, the position recognition unit 21 detects and recognizes that the vehicle has made a round along the wall and the cleaning area A, and confirms the wall surface with the distance measuring units 10 and 11, Based on the recognition by the position recognizing means 21, the position and the direction of the main body 1 are corrected in preparation for the next movement, and the operation is temporarily stopped.
[0033]
Next, cleaning movement of the inner part from the outer periphery is started by the inner moving means 23. As shown by the solid line arrow, the cleaning movement of the internal area is repeated by going straight and turning to advance the movement so as to substantially fill the area by the width of the cleaning nozzle 12, and the center obstacle 41 is detected by the distance measuring means 10, 11. This is a movement for cleaning the area while avoiding it. It is assumed that the avoidance operation moves along the obstacle 41 until returning to the predetermined internal area movement path, and the distance from the obstacle 41 is the same as the movement along the wall. The movement control means 9 stops the operation of the cleaning means when the position recognition means 21 and the distance measuring means 10 and 11 recognize that cleaning has reached the wall surface opposite to the start point S of the cleaning area A. Finally, the main body 1 returns to the start point S along the outer peripheral wall in the movement mode 25 along the wall 22 in the movement mode 25. After this, the system automatically enters the standby state for the start input. In the standby state, the power supply of the secondary battery 20 to the movement control means 9 is cut off in order to save the remaining amount of the secondary battery 20 as much as possible.
[0034]
Next, the operation of the features of the present invention, such as abnormality detection, audio display of abnormality contents / inspection contents, recording of abnormality history, and input after inspection, will be described again with reference to FIGS. 2 and 3 and FIGS. 6 to 8. I do.
[0035]
FIG. 6 is a flowchart of voice display when an abnormality is detected, FIG. 7 is an image diagram of an abnormality history stored in a storage unit, and FIG. 8 is a diagram showing correspondence between detected abnormality contents and messages and the like recorded in a predetermined location in advance. It is. Hereinafter, a description will be given along the flow of FIG. 6 as an example of a case where the remaining battery level of the secondary battery 20 is low, that is, when the remaining battery level of the secondary battery 20 is lower than a predetermined level.
[0036]
When an abnormality is detected (STEP 1), the content of the abnormality is written into the storage means 38 together with the date and time of occurrence measured by the clock 33 (a). Then, according to the measures shown in FIG. 8, the cleaning means is stopped (b) while the movement is continued. Next, the voice display means 31 displays "Battery is low" as a message indicating the content of the abnormality (STEP 2), and furthermore, "Charge the battery or replace the battery" as a message indicating the content of the inspection. Is displayed (STEP 3). The user follows these messages, and immediately thereafter, as an inspection work, performs a temporary stop input shown in FIG. 2 to temporarily stop the movement of the main body 1 and replace the battery (STEP 4). It is assumed that the input (STEP 5), that is, the check completion button 30 or 30 'is touched. At this time, it is recorded (c) that the inspection has been completed by inputting the date and time of the input of the inspection completion into the storage means 38 (upper left of FIG. 7). The cleaning means stop is released (d) by the input of the inspection completion, and once the stop of the movement is also released, the state of the main body 1 and the work state before the occurrence of the abnormality can be almost returned.
[0037]
Note that other abnormalities and inspection inputs that occur later are also stored as histories in an image as shown in FIG. Incidentally, the same wording as the voice message is displayed on the display unit 36 as shown in FIG. 2 during the voice display and during a predetermined time thereafter, or until a checked input is performed.
[0038]
The method of confirming the history is as described above. However, when the voice reproducing means 35 is input in the state of FIG. 3, the voice displaying means 31 plays a message as follows. "An abnormality with a low remaining battery was detected on September 30, 2002. The abnormality was resolved on October 2, 2002." If this case has not been checked, the second half of the message will display "Charge or replace battery".
[0039]
The above is an example of the content of the abnormality, and the present invention is not limited to this. Further, the contents and method of the character display on the display unit 36 and the voice display on the voice display unit 31 are not limited to the above.
[0040]
In addition, it is desirable to display both the content of the abnormality and the content of the inspection (or the input of the inspection already completed) on the audio display or the screen display of the display unit 36 in a polite but desirable manner. It is also possible to display only one of the content of the abnormality or the content of the inspection.
[0041]
Further, the position and the number of the sound generators 31 are not limited to those shown in FIG. 1, but it is more preferable to generate sound in all directions.
[0042]
Further, the movement pattern by the internal movement means 23 is not limited to that shown in FIG. 5, and may be, for example, repetition of straight traveling and random angle turns.
[0043]
The method of charging the secondary battery 20 is not particularly limited. However, it can be roughly distinguished depending on whether the secondary battery 20 is taken out or carried out while the secondary battery 20 is built in the main body 1. In any case, a separate charger is required. In order to perform automatic charging, it is conceivable that a station serving as a landmark is installed at the start point S and an automatic charging function is provided to this station.
[0044]
As described above, the user who is within the reach of the voice can confirm by voice that the abnormality has occurred and the content of the abnormality without approaching the main body or operating the device separately. Then, the user can perform the inspection work in accordance with the instruction of the voice display, and can resolve the abnormality. Further, it is possible to perform a checked input and return the movement control of the main body to a state before the occurrence of the abnormality. Further, since the abnormality history is recorded and accumulated in the storage means and can be freely checked later as needed, maintenance management becomes possible.
[0045]
