When using the G1 robot, the robot may be abnormal. Most abnormal situations are controllable (there
are solutions). The users should not panic when encountering these problems. Read the following contents in
detail and solve the problems step by step.
If you have any questions, please contact Unitree Robotics official technical support:support@unitree.cc.
1) Self-testing fails after startup
When the robot is suspended and turned on, if no sound is heard from the ankle hitting the limit after
waiting for 2 minutes, it indicates initialization failure. The robot has failed to start up, and the body should
be rechecked according to the two steps of "Check before Power on" and "Preparation before Power on" before
attempting again.
2) Self-testing fails after startup
In the use of Unitree Robotics official movement control program (control the robot move by using the
remote control), the robot will switch to self-protection status as a result of falling down caused by the external
environment reasons (lack of friction, etc.) on the surface or improper operation, the motor of the robot will
automatically switch to the braking state to protect the various parts.
3) App connection abnormality
If using the AP direct connection mode, check if the phone is connected to the AP hotspot emitted by the
G1. If the hotspot configuration fails, ensure that the hotspot name does not contain special symbols and spaces.
Also, ensure that the robot and the phone are close to each other, then restart the robot and the App to attempt
the connection again.
4) How to turn off the robot when the remote control module fails
When encountering the inability to use the remote control module due to the failure of the remote control
module (such as running out of battery on the remote control or mobile phone), the robot is suspended and
standby. It can only be forced to shut down by pressing the battery power button.
Forced shutdown: Hang the robot on a protective frame, with both feet suspended in the air, and maintain
a safe distance of at least 2 meters from obstacles, complex terrain, crowds, water surfaces, and other objects.
First, short press the power switch of the battery, and then long press for more than 2 seconds to turn off the
power.
5) The robot is easy to fall down and cannot stand when powered on
Robots are prone to falling during walking, and if restarting the robot does not solve the problem, it is
necessary to recalibrate the robot joints according to the relevant steps on the Unitree Explore App.
Note: G1 has been calibrated by default after leaving the factory. Do not recalibrate the joints for normal
use! If any abnormal situation occurs with the G1, please consult Unitree's official technical support before
determining whether joint recalibration is necessary.
The entrance for joint calibration in the App is [Settings] -> [Data] -> [Robot] -> [Calibration].
