Power-up

What happens, in order, and what it sounds like.

Before you power on

• Battery charged and plugged in.
• Kill switch remote in your hand.
• Gamepad front switch on X.
• Clear floor around the car.

The sequence

1. Switch the car on. Wait for the boot beeps.
2. Test the kill switch. Press B (falling pair). Press A (rising pair).
3. Wait for the robot software ready beep: low-low-high.
4. The car is in teleop mode. Hold the deadman and drive.

The beep vocabulary

The motor windings double as the speaker. Each event has a cue. Learn these six and you can hear the car's state from across the room.

Event	Cue
Boot OK (armed, battery good)	Rising triple, pause, low-high.
Kill switch armed	Rising pair.
Kill switch disarmed	Falling pair.
Robot software ready	Low-low-high.
Battery warning	Three mid beeps when stopped. Three long high chirps while driving.
Battery cutoff	Low-high-low, every 5 seconds until power-off.

If the boot beeps do not come

• Check the battery connector.
• Check the motor controller switch.
• Press A on the kill switch. The boot OK cue needs the switch armed.

If the car still makes no sound, write to support@goatracer.ai.

TODO (Rob): add how long a normal boot takes from switch-on to the ready beep.
