Functional Description
Laser Ranging is applied to measure the distance between the robot and surrounding objects
Navigation Module
based on the time difference of reflection, allowing the module to map against the objects around
while the robot is moving. The detection range is 8 m.
Laser Ranging and triangulation are used to measure the distance between the robot and
surrounding obstacles. The sensor emits laser beams and receives the reflected light from
Obstacle Avoidance Module
obstacles ahead. When an obstacle is detected within close range, the robot automatically turns to
avoid it. The detection range is 0.3 meters.
With Infrared Ranging, the distance between the robot's bottom and the ground is detected by
the infrared sensors at the bottom. The robot will not move forward when there are stairs in front
Anti-drop Sensors
(such as when the height of the white surface is 55 mm or more, or the height of the black surface
is 30 mm or more) and the identified exceeds the preset one, enabling the Anti-drop function.
The sensor emits 300 kHz ultrasound, which energy will be absorbed by the carpet, causing the
Carpet Detection Sensor
echoed energy to be lower than the threshold. The robot thereby detects the carpet's presence. In the
ECOVACS laboratory, more than 50 types of carpets available on the market are identified.
With the principle of the Optocoupler Switch, the robot will avoid obstacles when they are about to
Anti-collision Sensor
collide.
With Infrared Ranging, the edge sensor detects the distance between the robot and objects on the
Edge Sensor
side. When there is a wall or obstacles on the right, the robot performs edge cleaning to avoid missing
any spots and prevent collisions.
