Sensors
Name
TrueMapping Distance Sensor
TrueDetect 3D Sensor
Microphone
Anti-drop Sensor
Carpet Detection Sensor
With Laser Ranging-measuring the distance between DEEBOT and surroundings through the
time difference of re ection, it can map according to the objects around while DEEBOT is
moving. Detection of 10m
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
Vibrating the diaphragm through air by human voice, it can realize Voice Recording and ask
DEEBOT to complete the assigned work by Voice Control. Effective wake of 8m
With Infrared Ranging-detecting the distance between the bottom of DEEBOT and ground by
Infrared Sensor at the bottom, DEEBOT 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
The difference in energy of the ultrasonic echo signal on different surfaces is used to identify
the oor material and help DEEBOT to adjust the cleaning strategy automatically. Drive
frequency 290kHZ
