The invention relates to a cleaning robot and a material identification method thereof, which is suitable for cleaning robots. The cleaning robot is pre-set with a threshold comparison table and comprises a plurality of comparison thresholds, wherein each comparison threshold defines an interval of accumulated energy information accumulated by the moving plane of different materials within a predetermined period of time. The cleaning robot generates accumulated energy information during the movement, so that the cleaning robot can find the comparison threshold corresponding to the accumulated energy information from the threshold comparison table, and then determines the material of the moving plane contacted by the cleaning robot.

Cleaning robot and material identification method thereof

A cleaning path guidance method combined with a dirt detection mechanism is performed in an automatic cleaning device to generate a cleaning path, so as to guide the automatic cleaning device to clean an area to be cleaned, in which plural grids are defined in the area. The method includes: moving the automatic cleaning device in the area to clear dirt away, and continuously detecting a flow of the dirt cleared away to obtain a dirt level of a current gird; if the dirt level of the current gird exceeds a threshold, marking the grid as a dirty grid; performing an algorithm and finding a shortest path passing through all dirty grids as a cleaning path according to the marked dirty grids; and moving the automatic cleaning device to pass through each dirty grid according to the clean path, so as to clean each dirty gird sequentially.

Cleaning path guidance method combined with dirt detection mechanism

A cleaning robot including a roller unit, a sensing unit, a first control unit and a second control unit is disclosed. The roller unit includes a plurality of rollers. The sensing unit receives a reflection signal and generates a detection signal according to the reflection signal. When the detection signal is less than or equal to a reference signal, the first control unit controls the traveling direction of the rollers according to the detection signal such that a distance between the cleaning robot and a wall is equal to a first distance. When the detection signal is larger than the reference signal, the second control unit controls the traveling direction of the rollers according to the detection signal such that a distance between the cleaning robot and a wall is equal to a second distance larger then the first distance.
