Turned off
Charging is completed.
Blinks in red (or the Bluetooth connection indicator blinks slowly and intermittently in
dark blue)
Battery low
The charge indicator is blinking in red or the Bluetooth connection indicator is blinking
slowly and intermittently in dark blue if the battery of the robot is very low. In this case,
you have to charge the robot.
The Bluetooth connection indicator blinks slowly and intermittently in dark blue for the
Hamster robot produced in the beginning, while for the Hamster robot produced after
November 20th, 2015, the charge indicator blinks in red.
