Specifically, according to a predetermined program stored in the storage unit 14, a signal is transmitted to the servo motor SM corresponding to each joint unit, the servo motor SM is activated (the power is turned on), and each joint unit is activated. Rotation of the shaft joint mechanism is performed to move the limbs freely. It is desirable that the torque required to move the servo motor SM of the drive unit 11 when the power is off is larger than the torque due to the weight reaching the joint corresponding to the servo motor SM. This is because the posture of the figure 2 when the power is turned off can be maintained.
- control unit 12 does not turn on all the servo motors SM, turns on only some of the servo motors SM, and turns off the remaining servo motors SM. It may be. For example, when only a part of a plurality of shaft joint mechanisms is moved, the power of some servo motors SM corresponding to the part of the shaft joint mechanisms is turned on for a predetermined time, The power supply of the servo motor SM may be turned off for a predetermined time.

[1.フィギュアシステムの基本構成例]
図1Aは、本発明の第1の実施の形態としてのフィギュアシステムの全体構成を表す外観斜視図である。図1Bは、本実施の形態のフィギュアシステムの内部機構を説明するためのブロック図である。図1Cは、図1Aに示したフィギュアの外観を表す正面図である。図1Dは、図1Aに示したフィギュアを斜め後方から眺めたときの外観を表す斜視図である。
続いて、関節部の構成の詳細について説明する。各関節部は、1または複数の軸関節機構をそれぞれ含んでいる。ワイヤ4は複数のワイヤエレメント40(例えば40A,40B,41A,41B,42A,42B,43A,43B,…)を含んでいる。
例えば首関節部31は3つの軸関節機構を含んでいる(図1G参照)。具体的には、胴体上部20Aに対して鉛直方向の軸31J1を中心として回動する本体311により構成される軸関節機構と、本体311に対してフィギュア2の左右方向の軸31J2を中心として回動する回転部材312により構成される軸関節機構と、回転部材312に対してフィギュア2の前後方向の軸31J3を中心として回動する回転部材313により構成される軸関節機構との3つである。
また、例えば肩関節部32Lは2つの軸関節機構を含んでいる(図1G参照)。具体的には、胴体上部20Aに対して左右方向の軸32J1を中心として回動する回転部材321Lにより構成される軸関節機構と、回転部材321Lに対してフィギュア2の前後方向の軸32J2を中心として回動する回転部材322Lにより構成される軸関節機構との2つである。肩関節部32Lが含む2つの軸関節機構により、例えば軸32J1を中心として回転部材321Lが回動することにより、軸32J1を中心として左腕部22Lが前後方向(矢印Y321の方向)に回動することとなる。また、軸32J2を中心として回転部材322Lが回動することにより、左腕部22Lが上下方向(矢印Y322の方向)に回動することとなる。
図2A~2Fを参照して、2つの軸関節機構を含む手関節部35Lについて詳細に説明する。図2Aは、手関節部35L、その手関節部35Lに連結された前腕222Lを覆うカバー247、および手関節部35Lに連結された手223Lの外観を表す斜視図である。図2Bは、図2Aに示した前腕222L、手関節部35Lおよび手223Lからカバー247(247A,247B)を除去した状態を表すものである。図2Cおよび図2Dは、それぞれ手223Lの可動した状態を表すものである。図2Eおよび図2Fは、いずれも手関節部35Lを分解した状態を表すものである。
さらに図3A~3Eを参照して、1つの軸関節機構を含む膝関節部36Lについて詳細に説明する。図3Aは、膝関節部36L、その膝関節部36Lに連結された大腿231Lを覆うカバー242、および膝関節部36Lに連結された下腿232Lを覆うカバー241の外観を表す斜視図である。図3Bは、膝関節部36Lのみの外観を表す斜視図である。図3Cは、膝関節部36Lの分解斜視図である。図3Dは、膝関節部36Lの可動する様子を表す説明図である。図3Eは、膝関節部36Lの可動する様子を、カバー242およびカバー241と共に表す説明図である。
次に、図4Aを参照して、肩関節部32Lおよび肘関節部34Lを例に挙げて軸関節機構とワイヤとの関係について説明する。図4Aは、駆動部11から関節部への動力伝達を行う仕組みを説明する概念図である。図4Aに示したように、肩関節部32Lは、図1Gに示した回転部材321Lにより構成される軸関節機構を含んでいる。回転部材321Lは、軸32J1を中心として回転可能に胴体上部20A(図4Aには示さず)に支持されている。回転部材321Lには係止部材としてのピン321Pが固定されており、ピン321Pにはワイヤエレメント41Aの一端およびワイヤエレメント41Bの一端が取り付けられている。ワイヤエレメント41A,41Bは回転部材321Lの外縁に沿って引き回されている。なお、ワイヤエレメント41Aの一端とワイヤエレメント41Bの一端とが互いに接続されていてもよい。
本実施の形態のフィギュアでは、制御部12の指令に基づいてフィギュア2の動作制御を行う。具体的には、記憶部14に格納された所定のプログラムにしたがって各関節部に対応するサーボモータSMへ信号を送信し、そのサーボモータSMを起動し(電源オンの状態とし)、各関節部における軸関節機構の回転動作を実行させ、肢体を自在に動かすようにする。なお、電源オフ時における駆動部11のサーボモータSMを動かすのに要するトルクは、そのサーボモータSMに対応する関節部に及ぶ重量によるトルクよりも大きいことが望ましい。電源をオフにした際のフィギュア2の姿勢を保持することができるからである。
ここで、図4Aを参照して、肩関節部32Lおよび肘関節部34Lを例に挙げて上腕221Lおよび前腕222Lの動作について説明する。上腕221Lは、肩関節部32Lの回転部材321Lが回転することにより動作する。すなわち、サーボモータSM1の駆動力を、ワイヤエレメント41A,41Bを介して軸関節機構を構成する回転部材321Lへ伝達することにより、上腕221Lを動かすことができる。具体的には、制御部12からの信号に基づきサーボモータSM1が駆動し、その駆動軸53が例えば矢印R53+の方向に回転(右回転)すると、サーボホーン51も同方向へ回転する。このため、ワイヤエレメント41Bが引っ張られ、肩関節部32Lの回転部材321Lが軸32J1を中心として矢印R32+の方向へ回転(右回転)する。その結果、回転部材321Lに固定された上腕221Lが肩関節部32Lを支点として上方へ(胴体部20から離れる方向へ)回動することとなる。反対に、駆動軸53を矢印R53-の方向に回転(左回転)させればワイヤエレメント41Aが引っ張られるので、上腕221Lを下げる方向へ(胴体部20へ近づく方向へ)回動させることができる。なお、この肩関節部32Lおよび上腕221Lの動作に伴って、それよりも先端側に位置する肘関節部34Lおよび前腕222Lが影響を受けることはほとんどない。ワイヤエレメント42A,42Bが、回転部材321Lの中心部を貫いて延設されているからである。
本実施の形態のフィギュアシステムでは、台座1に、フィギュア2を駆動するための駆動部11を内蔵するようにした。このため、フィギュア2に駆動源を設けなくともよいので、フィギュア2の軽量化を図ることができるうえ、例えばスリムな形状を有するなどの審美性に優れたフィギュア2を実現することができる。フィギュア2の軽量化により、駆動に必要なサーボモータSMの出力を低く抑えることができるので、フィギュア2の寸法をより大きくすることもできる。フィギュア2の大型化をした場合であっても、低コスト化や転倒時の危険性の排除などの点で有利となる。また、フィギュア2を駆動するにあたり、駆動部11におけるサーボモータSMの駆動力を、ワイヤ4を介して各関節部へ伝達するようにしたので、フィギュア2の動作が安定し、高い動作再現性が得られる。そのうえ、シャフト、カムあるいはギアを動力伝達部材として用いた場合と比べ、動作上の高い自由度が容易に得られる。
(変形例1-1)
図5を参照して、上記第1の実施の形態に係るフィギュアの第1の変形例(変形例1-1)を説明する。本変形例では、ワイヤ4が、対応する軸関節機構ごとにチューブT(T1,T2)に収容されて延設されている。具体的には、例えば回転部材321Lに対応して設けられた1対のワイヤエレメント41A,41Bが、1本のチューブT1に収容されている。また、回転部材341L(図5では図示せず)に対応して設けられた1対のワイヤエレメント42A,42Bが、1本のチューブT2に収容されている。チューブT1,T2はフィギュア2の骨部材に沿って、例えばカバー24の内部に収容されている。チューブT1,T2は、その一部が把持部によって骨部材に固定されていてもよい。また、骨部材が中空構造である場合には、その骨部材の内部空間を通過するように設けられていてもよい。なお、チューブTは、例えばテフロン(デュポン社の登録商標)などの樹脂からなり、各ワイヤエレメント40に対する内面の摩擦係数が小さいものがよい。
次に図6Aおよび図6Bを参照して、上記第1の実施の形態に係るフィギュアの第2の変形例(変形例1-2)を説明する。本変形例は、1つのアクチュエータとしてのサーボモータSMにおける駆動力を、対応する1の軸関節機構に減速機構70を介して伝達するものである。減速機構70は、いずれも略円柱状をなし、同じ軸70Jを回転中心とする回転体71および回転体72を有する。回転体71は、軸70Jと直交する断面において直径71Dを有すると共に周面71Sを含むものである。一方、回転体72は、軸70Jと直交する断面において直径71Dよりも小さな直径72Dを有すると共に周面72Sを含むものである。周面71Sには1対のワイヤエレメント43A,43Bの各一端が固定されており、ワイヤエレメント43A,43Bは、軸70Jを取り巻く方向に周面71Sに沿って設けられている。同様に、周面72Sには1対のワイヤエレメント44A,44Bの各一端が固定されており、ワイヤエレメント44A,44Bは、軸70Jを取り巻く方向に周面72Sに沿って設けられている。
[1.脱着部の構成]
本開示の第2の実施の形態に係るフィギュアシステムを説明する。本実施の形態では、図7Aおよび図7Bなどに示したように、台座1が筐体10の上部に脱着部6Aを有し、フィギュア2がその下方に脱着部6Bを有し、脱着部6Aと脱着部6Bとが脱着可能に連結されている。本実施の形態はこの点を除き、他は上記第1の実施の形態と同様の構成である。こうすることで取り扱いが容易となるうえ、互換性を確保すれば、一つの台座1を複数のフィギュア2で共有することができる。
このように本実施の形態のフィギュアでは、台座1とフィギュア2とが脱着部6A,6Bにおいて脱着可能に連結されるようにした。これにより、取り扱いが容易となるうえ、互換性を確保すれば、一つの台座1を複数のフィギュア2により共有することができる。その結果、ユーザの利便性や経済性に有利となるうえ、故障の際にもその要因が特定されやすく、かつ、修理も容易となる。また、フィギュア2から導かれたワイヤ4の端部は脱着部6Bに接続されており、駆動部11のサーボモータSMには繋がっていない。このため、フィギュアシステムをメカ系統部分(フィギュア2)と、電気系統部分(台座1)とに完全に分離することができ、製造性またはメンテナンス性に優れている。
[1.全体構成]
図8および図9を参照して、本発明の第3の実施の形態に係るフィギュアシステムを説明する。本実施の形態のフィギュアシステムは、1または複数の軸関節機構を各々含む複数のモジュールMDが結合してなるフィギュア2Aと、それを支持する支持体3Aとを備えるようにしたものである。図8は、本実施の形態におけるフィギュア2Aの全体構成を概略的に表しており、図9は、本実施の形態における支持体3Aの断面構成を表している。
本実施の形態のフィギュアシステムでは、フィギュア2Aを複数のモジュールの結合体とした。このため、各モジュールMDを個別に製造し、最終的にそれらを組み立てることによりフィギュア2Aを完成させることができる。このため、生産性の向上を図ることができる。また、フィギュア2Aではモジュール単位での交換が可能であるため、修理等を容易にかつ速やかに行うことができる。よってメンテナンス性の向上も期待できる。
以上、いくつかの実施の形態および変形例を挙げて本開示を説明したが、本開示は上記実施の形態等に限定されるものではなく、種々の変形が可能である。例えば駆動源としては、ポリマーアクチュエータやソレノイドアクチュエータなどの他の簡易アクチュエータを用いることもできる。また、より大きな駆動力を必要とする関節部には、サーボモータにより直接駆動させてもよい。いずれにせよ、用途や使用に応じて異なる種類のアクチュエータを組み合わせて用いてもよい。
本開示では、例えば図10Aおよび図10Bに示したように、例えば胴体下部20Bに対して回転可能に設けられた胴体上部20Aを、複数のコイルばねBNの付勢力により、中立姿勢で保持するようにしてもよい。胴体上部20Aは、例えば互いに直交する回転軸30J1および回転軸30J2をそれぞれ回転中心として回転可能に構成されている。ここでいう中立姿勢とは、腰関節部30に接続された全てのワイヤエレメント40による駆動力が腰関節部30に伝達されていない状態の姿勢をいう。このように、複数のコイルばねBNを用いて胴体上部20Aを胴体下部20Bに対し弾性的に支持することで、中立姿勢での腰関節部30などのふらつきを防止し、フィギュア2の円滑な動作を促進することができる。なお、コイルばねBNの付勢力は、駆動部11からの駆動力(ワイヤエレメント40による牽引力)よりも弱い。このため、駆動部11による腰関節部30における軸関節機構の回転動作が阻害されることはない。なお、図10Aおよび図10Bは、胴体下部20Bと胴体上部20Aとの連結部である腰関節部30を拡大して表した正面図および側面図である。
図10Aおよび図10Bでは複数のコイルばねBNを用いて腰関節部30を支持するようにしたが、本発明はこれに限定されるものではない。例えば図11Aおよび図11Bに示したように、1つのコイルばねBNにより、頭部21を首関節部31の本体311に対し弾性的に支持するようにしてもよい。図11Aおよび図11Bは、胴体上部20Aと頭部21との連結部である首関節部31の近傍を拡大して表した正面図および側面図である。フィギュア2の各部位の重量などを考慮して、コイルばねBNの数量や付勢力を選択すればよい。また、コイルばねBNの代わりに、板ばねやゴムなどの弾性部材、あるいはオイルダンパなどの他の付勢部材を用いるようにしてもよい。
さらに、図12に示したように、台座1を防音ケース80の内部に配置するようにしてもよい。その場合、台座1を、例えば防音ケース80の底板80Aの上に緩衝部材としてのダンパ81を介して載置するとよい。さらに、台座1の上部を防音ケース80の天板80Bとコイルばね82などの弾性部材により繋ぐようにしてもよい。このような構造とすることにより、台座1の内部に設けられた駆動部11に起因する騒音が筐体10を介して防音ケース80に伝達されにくくなる。その結果、外部に漏れる駆動部11などの騒音が低減される。
また、ワイヤエレメント40を各々収容した複数のチューブTは例えば近接する軸関節機構ごとにグループ分けされ、それぞれのグループ単位で複数のチューブTが束ねられているとよい。その場合、例えば図13に示したように、樹脂フィルムなどからなるテープTPによりラッピングするようにするとよい。こうすることにより、例えば多数のチューブTが集まる胴体部20付近においてチューブT同士が絡み合う事態が回避される。その際、テープTPをグループごとに異なる色とすることにより、識別性を高めるようにするとよい。
