1) Go2 does not stand up after switching on with head flashing red light
Go2 head red light flashing slowly, this means power on failure, carefully check the robot power
on placement, re-position and then reboot. If the robot still fails to stand up, there may be system
abnormality or hardware failure, then you need to contact Unitree official technical support to
troubleshoot the problems.

If using AP connection mode, please check whether the mobile phone is connected to the AP

If using Wi-Fi connection mode, please check whether the connected Wi-Fi network is normal
and can connect to the external network.
If using 4G connection mode, please check the current traffic situation under [Settings]->[Mobile
Network] of the App to ensure that the 4G IoT card connects to the external network.
3) Can't use the App to control Go2?
Go2 cannot be controlled by companion remote control and App can't control Go2 at the same
time. If you want to use App to control Go2, please exit the side-following mode first. Press the power
button for 2 seconds to switch off the remote control. Then you can use the App to control Go2.
4) Abnormal standing posture after switching on
After Go2 is switched on, if walking posture is abnormal and it is easy to fall down, etc, and
restarting the robot cannot solve the problem, at this time, you need to re-calibrate the robot joints
according to the relevant steps in Unitree Go App.
Note: Go2 has been calibrated in factory default settings, please do not calibrate the joints for
normal use! Please consult Unitree's official technical support to determine whether you need to re-
calibrate the joints after Go2 has an abnormal situation!
App joint calibration entrance is [Settings]->[Data]->[Machine Dog]->[imu Information]->[Cali-
