1.3 TrueMapping Distance Sensor
Name
TrueMapping Distance Sensor
Anti-drop Sensor
Carpet Detection Sensor
Anti-collision Sensor
With Laser Ranging-measuring the distance between the device and surroundings through the
time difference of re ection, it can map according to the objects around while the device is
moving. Detection of 8m.
With Infrared Ranging-detecting the distance between the bottom of the device and ground by
Infrared Sensor at the bottom, the device will not move forward when there are stairs in front
(For example: White ground height greater than 30mm) or the identi ed distance exceeds the
present one, realizing the Anti-drop.
The ultrasound probe can emit ultrasonic waves with a frequency of 300KHZ. The energy of the
ultrasonic waves is absorbed by the carpet. If the re ected energy is below the threshold, the
device recognizes the presence of the carpet.
When the transmitted signal is blocked by an obstacle, the signal receiver will not be able to
receive the signal. With this principle, the device will avoid obstacles when colliding with them.
