Abstract:
A detection assembly for a cleaning robot includes: a light emitter, configured to emit test light; a darkroom having an access hole for light to enter the darkroom; a plurality of optical receivers, disposed in pairs in the darkroom and configured to receive light entering the darkroom via the access hole after being emitted by the light emitter and reflected by an external reflective surface and to convert a light intensity signal into an electrical signal; a detection circuit electrically connected to the plurality of optical receivers and configured to perform differential operation processing on the electrical signals of each pair of the optical receivers and to generate an output signal.

Claim (Index 14):
A method for detecting a walking condition of a cleaning robot, comprising:\n emitting test light to an reflective surface external to the cleaning robot; receiving light reflected by the reflection surface in pairs, determining a light intensity signal based on the received light; converting the light intensity signal into an electrical signal; performing differential operation processing on the electrical signals, wherein the differential operation processing is configured to determine a difference between the electrical signals; outputting an output signal based on the differential operation processing; converting the output signal into a distance value between the cleaning robot and the reflective surface; and determining position information of the reflective surface according to whether the distance value.
