Boot up

The posture before boot up

Drag the curly wire from the knee side to the shoulder side to avoid squeezing when the knee joints rotate. Put the joints into the following posture before turning on the power.

Power

Long-press the battery button for 3 seconds to turn on/off. You will hear a short melody, and the battery indicator will turn blue. If the indicator is red, please take a look at the charging method below.

After turning on the battery, the robot requires approximately 5 seconds for initialization, after which a melody will play.

The robot's battery charge may decrease during storage and transportation. Please ensure the battery is fully charged when using it for the first time.

It is recommended that the robot be placed on the calibration stand before pressing the button to activate the battery (Optional).

If you use the robot on the floor, please ensure it's upright after activating the battery. Otherwise, upon start-up, it will continuously attempt to flip itself over or perform other corrective motions.

If the robot is placed on its side when powered on, it will automatically initiate the calibration posture.

Battey Indicator

Before you use it, please read the instructions on the bottom of the packaging box carefully to make sure the battery's correct operation.

Low Power Full Power Intermediate Power

During charging, the indicator light turns red; after charging is complete, it turns green. Press the blue button briefly to check the battery status:

· When fully charged, short-press the button on the battery, the indicator light is blue.

· When the voltage is low, the indicator light is red.

· During battery depletion, the indicator color gradually changes from blue to red.

Note the correct use of battery interfaces: Use the Type-C interface for charging, and the 2P 2.54 mm red-black wire terminal interface to power the robot. Please don't mix them up.

If the robot detects a low battery, it will pause its movements and beep. You must detach and charge the battery using a standard 5V USB Type-C interface data cable. The battery will automatically stop supplying power to the robot during charging for safety reasons.

Buzzer sounds

[1]. The startup melody in normal mode starts at 00:13 in the video below.

[2]. The repetitive melody starts at 00:21 in the video below.

Other Situations

Charging

The robot's battery socket has limited dimensions, so when the battery is installed on the battery seat, it cannot be directly charged via USB. The battery needs to be detached from the battery socket before charging.

Before charging, please turn off the battery (long-press the battery button for 3 seconds). After connecting the charging cable, the battery will automatically shut down (cease external power supply).

Please do not confuse the mainboard’s upload port with the battery charging port.

Device Freezing or Unresponsive

There are two solutions：

1. Check the battery indicator light. If the battery level is too low, please charge it immediately.

2. If the battery level is normal, remove the back cover and press the reset button on the motherboard next to the LED logo to reboot the robot.
