Cool robot!
A bit unusual to see at FA so I got curious about the text.
Tested various translation services to see how they would translate it to English.

Yandex: NO. 6 Initial magic power “Through experiments, magic, perfect to add in machinery and to provide power.”

Youdao: NO. 6 The initial magic power "After the experiment, the magic perfect add on mechanical and power."

Babylon: The initial impetus NO.6 Magic "After experiments, the magic perfect add on mechanical and provide impetus. "

Baidu: NO.6 Initial magic power "After the experiment, the magic is perfect to add to the machine and provide power."

Google: NO.6 Initial magic power "After the experiment, the perfect addition to the mechanical and magic powers."

Bing: NO.6 The initial magic power "After the experiment, perfect added to mechanical power and magic. ”


And my own guess from seeing all of the above:
The magic power-up of number 6
The experiment successfully used magic to power the machine.
