Robotic cleaning device with dynamic area coverage
A method of moving a robotic cleaning device through an area includes loading instructions for a plurality of geometric elements. Each geometric element includes a starting point, paths of travel, and waypoints. An ending waypoint of a first geometric element is connected to the starting point for a subsequent geometric element. The instructions for each geometric element do not include dimensions for the one or more paths of travel. The instructions cause the robotic cleaning device to move along a first path of travel of the first geometric element until a sensor of the robotic cleaning device detects that the robotic cleaning device has reached a first waypoint. Then, if the first waypoint is the ending waypoint of the first geometric element, the robotic cleaning device moves along to the subsequent geometric element or changes direction and moves along a second path of travel of the first geometric element.
1. A method of moving a robotic cleaning device through an area, the method comprising:
by a processor of a robotic cleaning device, loading instructions for a plurality of geometric elements, wherein:
each geometric element includes a starting point, one or more paths of travel, and one or more waypoints,
an ending waypoint of a first geometric element is connected to the starting point for a subsequent geometric element, and
the instructions for each geometric element do not include dimensions for the one or more paths of travel; and
by the processor of the robotic cleaning device:
causing the robotic cleaning device to move along a first path of travel of the first geometric element until a sensor of the robotic cleaning device detects that the robotic cleaning device has reached a first waypoint,
if the first waypoint is the ending waypoint of the first geometric element, causing the robotic cleaning device to move along a first path of travel of the subsequent geometric element, and
if the first waypoint is not the ending waypoint of the first geometric element, causing the robotic cleaning device to change direction and move along a second path of travel of the first geometric element.
2. The method of claim 1 , further comprising, by the robotic cleaning device as the robotic cleaning device moves along each path of travel, operating a cleaning assembly of the robotic cleaning device to clean an area that includes each path of travel.
3. The method of claim 1 , further comprising detecting, by the sensor, the first waypoint by detecting that the robotic cleaning device has come within a threshold distance from a first obstacle, step or change in floor type that is in front of the device in the device's direction of travel along the first path of travel of the first geometric element.
4. The method of claim 1 , further comprising detecting, by the sensor, the first waypoint by detecting a visual marker that is positioned along the first path of travel.
5. The method of claim 1 , further comprising detecting, by the sensor, the first waypoint by receiving a communication via a beacon that is located at the first waypoint.
6. The method of claim 1 , wherein a geometric element includes a defined offset, which instructs the robotic cleaning device to clean only certain portions of an area associated with said geometric element.
7. The method of claim 1 , wherein a geometric element is defined as a move area, which instructs the robotic cleaning device to not clean an area associated with said geometric element and to move to an ending waypoint of the geometric element defined as the move area, said ending waypoint being connected to a starting point for a subsequent geometric element.
