Please make sure that the robot turned off in a damping state, otherwise the robot will fall heavily on the ground after it is turn down and powered off, which may cause damage to the robot body and certain potential hidden dangers! If the power on fails, please check if the robot body is placed correctly.

Explanation of abnormalities
When using Go2 quadruped robot, robot abnormalities may occur. Most of the abnormalities are controllable (with solutions), customers should not panic when encountering these problems, read the following content and follow the following steps to solve the problem.

If you have any questions, please contact the official technical support of Unitree: support@unitree.cc.

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.

App connectionerror error

If using AP connection mode, please check whether the mobile phone is connected to the AP hotspot issued by Go2.
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.

Can’t use the App to control Go2?
Go2 cannot be controlled by the 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.

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 recalibrate the robot joints according to the relevant steps in the 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 recalibrate the joints after Go2 has an abnormal situation!
App joint calibration entrance is [Settings]->[Data]->[Machine Dog]->[imu Information]->[Cali-bration].

Radar stops rotating when meet an external force
Normally, when relieving external force, the radar will automatically resume rotation. If it still can’t work, you can try to make the radar roll by fiddling with your hand. If the problem still remains unsolved, please try to restart Go2. If it can’t be solved after restarting, you can check the malfunction details on the app, and consult with Unitree’s official technical support.

Restore Factory Settings
The reset button is on the back of Go2, which can complete the factory setting of Go2. The operation method is as follows: press the reset button (long press, do not release) in the power off state, power up the Go2 battery (short press + long press for 2 seconds), then you can reset the factory settings. Wait for the yellow light blinking after powering up Go2, at this time you can release the reset button and wait for the green light on the head of Go2, The system reset is successful, it takes about 30 minutes. When reset, please make sure that robot dog still has 3 or more bars of battery power!

Cautions

Please make sure that the robot is lying down for switching off, otherwise the robot will fall heavily on the ground after switching off and powering off, which may cause damage to the body and remain certain hidden safety hazards!
When standing up, when the ground friction is insufficient or the robot’s feet are not reliably supported, please do not operate the robot strenuously to adjust its posture (including pitching, rolling, yawing, fuselage height adjustments, etc.), otherwise it may cause the robot to fall down.
Please walk the robot on flat terrain. If you are walking on ground with low friction, do not operate the robot strenuously, otherwise it may cause the foot end to slip and fall.

The rated endurance of the robot is about 1-2 hours with no load static standing and upright walking alternately. It depends on the actual operating conditions of the robot, such as walking at a faster speed for a longer period of time, drastically adjusting the body attitude for a longer period of time while the robot is standing, standing with the robot legs bent, running with a load, walking at a lower body height, and terrain with appropriate undulations and slopes, etc., which will reduce the endurance time. (Lower body height and more knee bends place a greater burden on the motors and therefore increase power consumption significantly earlier and are accompanied by motor heating).
Because the levels of proficiency of the operator are different. To safety reasons, it is not currently recommended that robot walk stairs higher than 16cm, otherwise it is likely to trip over the foot due to improper operation. When encountering undulating ground, the operator should also be careful and reduce the speed of the robot. (AIR version has a maximum climbing drop height of 15cm).
Go2 is rated for a positive climbing angle of less than or equal to 40°. When a larger climbing angle is used (approximately equal to or greater than 40°), the robot body is likely to drift sideways, and direct turns on slopes with a large gradient are likely to destabilise the robot; reduce walking speed when climbing; proper control by the operator is required. (Maximum slope is 30° for AIR version).

Go2 can reach a maximum speed of 3.5m/s on flat terrain. (Maximum speed 2.5m/s for AIR version).
The robot foot end is a consumable item and a spare foot end will be included with the delivery. Especially walking on relatively rough ground, it will be worn out seriously. If there is obvious foot pad abrasion, damage, or loud noise when the robot walking on the ground, please replace the foot end in a timely manner, so as to avoid the damage to foot and malfunction of the robot movement.
It is forbidden to use the robot on the occasions where the terrain is complicated, the ground is wet, there are sundries on the ground, the terrain is undulating (steps higher than 16cm, etc.), and the slope is large (more than 40°) and there are sharp objects on the ground or in the periphery.

Hand may be pinched at the motion joints, such as at the knee joint. Please be careful.
