Abstract: An object determining system, comprising: a processing circuit; a first stage object sensor, for generating a first stage object sensing result of an object; and a second stage object sensor, for generating a second stage object sensing result of the object if the processing circuit determines the object exists in a predetermined range based on the first stage object sensing result, wherein the processing circuit further determines an object kind of the object based on the second stage object sensing result; a line light source; and an area light source. The first stage object sensor generates the first stage object sensing result based on the line light. The second stage object sensor generates the second object detecting result based on the plane light. The first stage object sensor is a depth sensor or a thermal sensor. The second stage object sensor is an image sensor or a thermal sensor.

Abstract: A method for eliminating misjudgment of a reflective light applied to an autonomous robot is provided. The autonomous robot includes a driving system and an optical sensing system that includes a light source and a light sensor. The light source emits a transverse linear light as detection light and the light sensor senses reflective light signals from an object that reflects the detection light. In the method, a frame image including the reflective light signals is captured by the light sensor, characteristics of the reflective light signals are analyzed, and the characteristics of the reflective light signals can be corrected based on the characteristics of previous reflective light signals stored in a memory of the autonomous robot in order to exclude abnormal information. The object can be confirmed based on the corrected characteristics of reflective light signals. The misjudgment caused by the abnormal information can therefore be eliminated.

Abstract: There is provided a mobile robot that controls an exposure time of an optical sensor during a time interval during which images of a gap between tiles are captured. At an end of the time interval that an image of a gap between tiles is captured, the exposure time of the optical sensor is adjust to the exposure time being used right before the time interval to avoid high brightness of the captured image while the image of a gap between tiles is suddenly disappeared from a field of view of the optical sensor.
