おもちゃすぐ無くなる問題をどうにかしたかった

Last updated at 2023-11-07Posted at 2023-11-05

おもちゃ、すぐどっかいかない？

子育てしている方、今うなずきましたよね？
家の中なのに、おもちゃすぐどっかいく。

我が家も同じです。
片付けようとして、あれ、一個ない、、、
大抵、家具の下に転がってるんですよね。

転がってしまったおもちゃを検知して、教えてくれる、
そんな装置あったらいいなと思って、挑戦してみました。

使ったもの

Node-RED
LINE messaging API
obniz Board 1Y

パーツ

サーボモータ
超音波距離センサー
ジャンパーワイヤ
ブレッドボード
アンパンマンスプーン（おもちゃ）（※子どもにバレないように拝借）

これが

こうじゃ

一旦、おもちゃレスキュー君と呼ぶことにする。

完成したものがこちら

機能説明の前に、おもちゃレスキュー君を
実際に動かしてみます。（※家具の下想定でご覧ください）

昨日も今日も明日も、転がってどっか行ったおもちゃを探してるパパママへ、、#obniz #protoout #おもちゃレスキュー pic.twitter.com/LTtzknNj03
