Abstract

A mud treatment system that can be used during emergencies is disclosed. The system includes an autonomous vehicle carrying a mud treatment device. In response to information about a mud-related disaster at a specific location, the system will instruct the vehicle to travel to the location, enter a building, and dispense one or more applications of mud softener in the interior space of the building. The vehicle can navigate from room to room and determine whether moisture content levels are below a specified threshold. In response, the vehicle can direct its mud or dirt softening efforts to these specific zones.

causing, via the onboard computing system and at a second time, a mud softener device installed on the first autonomous vehicle to dispense a first application of softener onto the first mudflow.

2 . The method of claim 1 , wherein the first mudflow has a first volume at the first time and a greater, second volume at the second time.

3 . The method of claim 1 , further comprising:

obtaining, via the first sensor, second sensor data about a second portion of the first room;

detecting, via the onboard computing system for the first autonomous vehicle and based on the second sensor data, a second mudflow in the second portion;

determining, at an onboard computing system for the first autonomous vehicle and based on the second sensor data, that a second moisture content level for the second mudflow is greater than the first threshold level; and

causing, via the onboard computing system, the first autonomous vehicle to navigate away from the second portion.

4 . The method of claim 1 , further comprising:

obtaining, via the first sensor, second sensor data about a second portion of the first room;

detecting, via the onboard computing system for the first autonomous vehicle and based on the second sensor data, a second mudflow in the second portion;

determining, at an onboard computing system for the first autonomous vehicle and based on the second sensor data, that a second moisture content level for the second mudflow is less than the first threshold level; and

causing, via the onboard computing system, the first autonomous vehicle to navigate toward the second portion.

5 . The method of claim 4 , wherein the hole is a tunnel extending from a first side of the wall to a second side of the wall, and the method further comprises causing, via the onboard computing system, the mud treatment device to dispense, through the tunnel, a second application of mud softener into a space that is adjacent to the second side of the wall.

6 . The method of claim 1 , further comprising:

transmitting, prior to the first time, a first signal identifying the target location from a remote computing system for a mud treatment service to the first autonomous vehicle, the first autonomous vehicle being stationed in a drone repository; and

causing, via the onboard computing system and in response to the first signal, the first autonomous vehicle to execute a path from the drone repository to the target location.

7 . The method of claim 6 , further comprising:

determining, via the onboard computing system, that an assessment of the first building has been completed;

causing, via the onboard computing system, the first autonomous vehicle to execute a return path from the target location to the drone repository;
