4.About Steps and Undulating Pavement：
Since the robot does not have a visual perception system, and the actual controller has different
levels of proficiency in control, the current version does not recommend the customer to walk more
than 10 cm for the sake of reliability and stability, otherwise it is likely to be caught due to improper
operation. The control personnel should also be cautious when encountering undulating ground
and reduce the speed of the robot.
5.About Climbing：
The rated forward climbing angle is less than or equal to 25°. Since the robot does not have a visual
perception system at present, when using a large climbing angle (about equal to or greater than
25°), the robot body is likely to have a more lateral drift, especially when using the Trot gait; The
visual perception system, which makes a direct turn on a slope with a large slope, is likely to
destabilize the robot; when climbing the slope, please reduce the walking speed; it needs to be
controlled by the controller.
6.About Speed：
The maximum speed can reach 3.3m/s under the stable control of flat terrain.
7.About the Robot Walking by the Track：
The official delivery version may support the robot on a flat or square track with pre-set conditions.
8.About the Robot Body Posture Adjustment Combined Action
(including pitch, roll, yaw, body height adjustment, etc.)
The official delivery version may support the standing state, level the ground, under the premise of
pre-setting, the robot performs a series of body posture adjustment combined actions according to
certain rules.
9.About Footpad：
The robot footpad is a consumable item, and we will give you an alternate footpad. Especially when
running on rough ground, the wear will be more serious. If the obvious foot pad is found to be
worn or damaged, or the impact noise on the ground is obviously increased when the robot is
walking, please replace the foot pad in time to avoid damage to the foot. Foot sensor (such as force
sensor).
10.It is forbidden to be complicated on the ground, the ground is slippery, there are debris on the
ground, the terrain is undulating (step is higher than 10cm, etc.), the slope is larger (greater than
25°), and the robot is used when there is a sharp object on the ground or the periphery.
11.Carefully grip the joints at the joints, such as the knee joint.
