Navigational control system for a robotic device
First Claim
1. A robotic cleaner, comprising:
- a chassis and an outer shell secured to the chassis;
left and right main drive wheel assemblies and respective independent electric motors, independently mounted in pivotally-biased combination with the chassis for pivotal motion with respect thereto at opposed ends of the transverse diameter of the chassis, and movable between a retracted position under the weight of the robotic cleaner during operation and an extended position wherein their axes of rotation are below the bottom plane of the chassis;
a navigational control system operative to monitor movement activity of the robotic cleaner within a defined working area, the monitored movement activity including at least one of a position history of the robotic cleaner and an instantaneous position of the robotic cleaner; and
a transmitting subsystem including a transmitter laser, wherein the transmitter laser;
is configured to redirect a transmitting element of the transmitter laser;
is configured to cover the defined working area by transmitting a beam substantially parallel to a surface of the defined working area;
is mounted in combination with the outer shell secured to the chassis to define an overall structural envelope of a height to enable movement of the robotic cleaner under furniture; and
is integrated in combination with a high point of a housing infrastructure of the robotic cleaner so that any structural features of the robotic cleaner below the transmitter laser do not substantially interfere with redirection of the transmitting element of the transmitter laser.

Abstract
A navigational control system for altering movement activity of a robotic device operating in a defined working area, comprising a transmitting subsystem integrated in combination with the robotic device, the transmitting subsystem comprising means for emitting a number of directed beams, each directed beam having a predetermined emission pattern, and a receiving subsystem functioning as a base station that includes a navigation control algorithm that defines a predetermined triggering event for the navigational control system and a set of detection units positioned within the defined working area in a known spaced-apart relationship, the set of detection units being configured and operative to detect one or more of the directed beams emitted by the transmitting system.
