A Twitter user @suzuki_jidouka (Suzuki is a Japanese surname, jidouka means automation) showed that he had created a robot for his little sister who wants to earn more coins on coin pusher game on smartphone.
妹から『コイン落としのゲームで効率的に稼ぎたいからスマホ画面を1秒間に2回くらい一晩中タップし続ける機械が作れないか』と,かなりヨコシマな打診あり。仕方ないので作成。子供がいるので安全性の配慮となるべくシンプルな作りに気をつけたつもり pic.twitter.com/BF1eDusFOK

The sister asked him if she would earn points effectively by tapping the smartphone screen twice per second all through the night (while she sleeps).
Suzuki assembled this machine with Tamiya’s construction kits, with caring safety for kids.
It worked good but the only problem is that it makes pretty big noise.
