⭐ Operation Test

1. Launch MiraPlay AiO

Open MiraPlay AiO, log in to your account, and connect MiraBot.

First time using MiraPlay AiO? Please see the MiraPlay AiO User Guide.

2. Run the motion test

Go to My → Motion Test.
Each slider corresponds to a motion axis.

Move each slider to confirm all axes operate normally.

Displayed axes differ by model:

• S6: 6 axes (including Twist)
• Lite / S2+: 4 axes (including Twist)

⭐ Initial Position Check (Horizontal Alignment)

After powering on, check whether both arms are aligned on the same horizontal plane in their initial position.

If alignment is off:

1. Open My → Arm Initial Settings.
2. Fine-tune each axis using + / −, based on the default value (1500).
   • + = clockwise micro-adjustment
   • − = counterclockwise micro-adjustment
