- * IX: Oplev setting will be finished by 3/10. Mystery of 5-kg overload. The ballast on the F0 is too tall.

- * [Miyo] オフロード作業を無くすためのアイデア募集
  * 問題意識：真空圧力が変わるとIPが傾いてPayloadが自身のEQフレームに当たる。（完全に傾かないようにする治具はそもそも不可能なので、傾いても大丈夫なアイデアがほしい。）
  * [Miyo] そもそも、IPが傾いてIPのEQストップに当たった状態でもPayloadも同じく当たらないよう十分に退避させれば良い話に思える。その場合、IPがEQに当たった状態でFRをつかってもとに戻せるかどうか確認すべき。これはAcceptanceCheckに追加すべきか？
