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.

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.
