3D Print Data
The 3D print data is available below. Please print four sets of parts from the 'leg' folder, as each set corresponds to one leg.
3Dプリント用のデータは以下にあります。legフォルダ以下の部品は1本分なので4個印刷してください。
The fully assembled main body and each leg (two types, diagonal combinations) is uploaded in STEP format. Please refer to them during assembly.
組立済の本体全体・各脚(対角の組合せで2種類)はSTEP形式でアップロードしてありますので、参考にしてください。

Software: Software
There are sketches for ArduinoIDE in the 'examples' folder. There are two types available for web interface and ESP-NOW.
ArduinoIDE用のスケッチがexample以下にあります。Webインターフェース用とESP-NOW用の2種類があります。
Controler with Web Interface
It starts as a WiFi access point and can be controlled from a web browser.
WiFiのアクセスポイントとして起動し、Webブラウザからコントロールできます。
Controller for ESP-NOW mode
The source code for the ESP-NOW controller is available below. Here, a modified Famicom controller is used.
