	Battery status	Green: Battery OK. Red: Battery low
	Power button	Green: robot is on. Off: robot is off

Corner LEDs

The corner LEDs use the following patterns to indicate the robot’s status:

Front LEDs	Rear LEDs	Description
Solid white	Solid red	Normal operation
Pulsing orange	Pulsing orange	Battery is low
Flashing orange	Flashing orange	Fault
