🟢 Green – Recording is in progress and sensors are collecting data

Before You Start
Connect an External Power Bank
Keep RoboCap connected to an external power bank during normal use.
RoboCap has a built-in 7.4V 500 mAh / 3.7 Wh battery, but this is intended primarily as a backup power source.
Battery Behavior
With an external power bank connected:
RoboCap uses the external power source first
The built-in battery charges automatically
A 10,000 mAh power bank provides approximately 5–5.5 hours of use
Without external power:
RoboCap automatically switches to its built-in battery
The built-in battery supports approximately 5–15 minutes of use
Important: Do not rely on the built-in battery for normal recording. Keep RoboCap connected to an external power bank to avoid interruptions.
Adjust the Fit
RoboCap has an adjustable head strap. Adjust the strap so the cap sits securely and comfortably on your head and does not move around during recording.
