Name Functional Description
TrueMapping
By utilizing the principle of triangulation, which involves emitting
and receiving laser beams reected by surrounding objects,
precise distance measurement information between the robot
and nearby objects can be calculated through algorithms� When
the robot moves within a certain environment, the positions of
surrounding objects are determined to create a spatial map of
the robot's surroundings� The measurement range is 8 meters�
TrueDetect 3D
Sensor
The TrueDetect 3D structured light sensor scans the object
with a line laser and collect images with a monocular camera,
and generates the three-dimensional coordinates of the object
through image algorithms to identify the size of the object� The
detection distance is 0�35m
Anti-drop Sensor
With Infrared Ranging-detecting the distance between the
bottom of robot and ground by Infrared Sensor at the
bottom, robot will not move forward when there are stairs in front
or the identied distance exceeds the preset one, realizing the
Anti-drop� The trigger distance is 60mm�
Carpet Detection
Sensor
The difference in energy of the ultrasonic echo signal on different
surfaces is used to identify the oor material and help robot
to adjust the cleaning strategy automatically� Drive frequency
290kHZ�
Edge Sensor
By the principle of infrared ranging, the robot detects the
distance between itself and objects on its side� When there is
a wall or obstacle on the right side, the robot performs edge-
cleaning operations to avoid missing any spots and collisions�
Anti-collision
Sensor
When the transmitted signal is blocked by an obstacle, the signal
receiver will not be able to receive the signal� With this principle,
robot will avoid obstacles when colliding with them�
SENSORS NOTES BEFORE CLEANING
Put away objects including cables, cloths and slippers, etc� on the
oor to improve the cleaning efciency�
Before using the product on a rug with tasseled edges, please fold
the rug edges under�
Please do not stand in narrow spaces, such as hallways, and make sure
not to block the TrueMapping Distance Sensor�
Tidy up the area to be cleaned by putting
furniture, such as chairs, in their proper
place�
During the rst use, make sure each room
door is open to help robot fully explore your
house�
It may be necessary to place a physical
barrier at the edge of a drop to stop the
unit from falling over the edge�
