ユカイ工学さんのファミリーロボットBOCCO emoをつい先日知り、自分のやっているスマートホームに組み合わせられそうだなのでとても期待しています。
前回は、スマートホームで人とデバイスとのインターフェースとしてBOCCOemoはAPI使えるから可能性を感じている件という記事でAPIを試してみました。
今回はたくろーどん（@takudooon）さんがzennに「BOCCO emo をNode-REDから入力したテキストで発話させてみる」という記事を書かれていたので、この記事を見ながらNode-REDとBOCCO emoを連携させてみたいと思います。
アクセストークンの定期取得
たくろーどんさんのフローをそのままインポート。
取得したアクセストークンをchangeノードでglobalに格納してるんですね！いままでこういうことはfunctionノードでやってたけど、こっちのほうがわかりやすい！勉強になります。
リフレッシュトークンはアクセストークンを取得するときだけ必要だから、これもchangeノードにいれているので、すごくシンプルにわかりやすくできてる。
そして、グローバル変数がコンテキストデータから確認できることも知らなかった！
この記事読んだだけで、Node-REDの経験値がかなり上がります。
部屋一覧の取得
たくろーどんさんのフローをそのままコピペして部屋の一覧を取得するフローを動かします。
“部屋のIDもグローバル変数で管理し呼び出して使っても良いと思います。”
とたくろーどんさんが書かれていたので、部屋のIDをグローバル変数”uuid”に格納するフローを追加しました。
http requestからのレスポンスをjsonにした後、
部屋のIDをglobal.uuidに格納します。
コンテキストデータからも確認できました。

メッセージを送信
こちらもたくろーどんさんのフローをコピペした後、部屋のIDをglobalから取得してhttp requestノードのURLに反映させるように修正しました。
msg.payload = "Bearer " + global.get("access_token");
msg.url = "https://platform-api.bocco.me/v1/rooms/"+ global.get("uuid") +"/messages/text";
return msg;
“JSONのデータ作成”のfunctionノードにはグローバル変数からuuidを取得してそれをmsg.urlに入れています。
こうすることで、http requestノードのURLにはmsg.urlの値が使われるようになります。
全体のフロー
ということで、たくろーどんさんのフローで勉強しながら、部屋のIDをグローバルにしたぷち改良フローです。

まとめ
以上、たくろーどんさんのフローを元に、Node-REDからBOCCO emoにメッセージを送るテストをしてみました。
次は、KNXやModbusなどのセンサーデータをBOCCO emoに喋らせることなど試していきたいとおもいます。
引き続き、BOCCO emoの可能性を探っていきます。
