Wet floor detection and notification

A method for providing a notification of a wet floor, the method comprising:

• (a) providing a liquid for cleaning a floor with a scrubbing robot;
• (b) collecting sensor data about an area of the floor proximate to the scrubbing robot and along a path over which the one or more liquid carrying components have travelled, wherein the sensor data is collected from a sensor coupled to the scrubbing robot;
• (c) providing a set of threshold parameters indicative of the presence of liquid on the floor, wherein the set of threshold parameters is stored on a computer coupled to the scrubbing robot;
• (d) determining that liquid is on the floor by analysing the data for a presence of a second set of parameters corresponding to or crossing, from above to below or from below to above, the set of threshold parameters;
• and
• (e) issuing at least one of:
• an audio notification, a visual notification, a physical notification and a computer-detectable notification from a notification module coupled to the scrubbing robot in response to a determination that liquid is on the floor.

A system for providing a notification of a wet floor, the system comprising:

• (a) a scrubbing robot for scrubbing a floor using a liquid, wherein the liquid is carried in a container coupled to the scrubbing robot;
• (b) a sensor coupled to the scrubbing robot for measuring a quantifiable attribute of the liquid carried by the scrubbing robot;
• (c) a computer coupled to the scrubbing robot, the computer comprising a computer readable memory and a processor;
• (d) a threshold value of the quantifiable attribute, the threshold value stored on the computer readable memory, wherein the threshold value is indicative of at least one of:
• the scrubbing robot carrying at least a prescribed quantity of liquid and a rate of depletion of liquid from the scrubbing robot;
• (e) an application stored on the computer and executable by the computer for determining that the floor is wet by determining that the scrubbing robot is carrying less than the prescribed quantity of liquid or that the rate of depletion of liquid from the scrubbing robot is too high by comparing the threshold value to a value of the quantifiable attribute measured by the sensor;
• and
• (f) a notification module coupled to the scrubbing robot for issuing at least one of:
• an audio notification, a visual notification, a physical notification and a computer-detectable notification in response to the application determining that the scrubbing robot is carrying less than the prescribed quantity of liquid or that the rate of depletion of liquid from the scrubbing robot is too high.
