Abstract
An autonomous robot, that is for example, suitable for operations such as vacuuming and surface cleaning includes a payload configured for vacuum cleaning, a drive system including a steering system, a navigation system, and a control system for integrating operations of the aforementioned systems.
Claims35
An apparatus for autonomous operation over an area comprising:
- a drive system;
- and
- a controller in communication with said drive system, said controller including a processor programmed to:
- provide at least one scanning pattern for a first portion of said area;
- analyze said first portion for an opening to a second portion of said area;
- and
- signal said drive system to move along a path at least proximate the periphery of said first portion to and through said opening to said second portion of said area.

An apparatus for autonomous operation over an area comprising:
- a drive system;
- and
- a controller in communication with said drive system, said controller including a processor programmed to:
- provide at least one scanning pattern for a portion of said area from a first point;
- signal said drive system to move along a path at least proximate the periphery of the scanned portion to a second point, said second point at a different location than said first point;
- and
- provide at least one scanning pattern for a portion of said area from said second point.
4 more elements
A nozzle for suction of particulates comprising:
- a body, said body including a first end and a second end, said first end including a neck, and said second end including an upper edge and a lower edge defining an opening therebetween;
- a lip extending at least substantially parallel to said opening along said upper edge and extending at least partially beyond said lower edge of said opening, said lip tapering upward from a portion of greater thickness to portions of lesser thickness, said lip configured for creating a flow cavity to be formed with the floor or surface over which said nozzle traverses.
A method for area coverage by an autonomous machine comprising:
- scanning a first portion of said area in accordance with at least one scanning pattern;
- analyzing said first portion for an opening to a second portion of said area;
- and
- moving along a path at least proximate to the periphery of said first portion to and through said opening to said second portion of said area.

A method for area coverage by an autonomous machine comprising:
- scanning a portion of said area in accordance with at least one scanning pattern, from a first point;
- moving along a path at least proximate the periphery of said scanned portion to a second point, said second point at a different location than said first point;
- and
- scanning a portion of said area in accordance with at least one scanning pattern, from said second point.

An obstacle detection system for an autonomous cleaning machine comprising:
- a control system;
- a nozzle, said nozzle including a first end for receiving particulate inflow, and a second end for communicating with a suction generating unit, said second end including arms;
- a height adjustment system coupled to said first end of said nozzle, said height adjustment system in communication with said control system;
- and
- receiver portions configured for receiving said arms in a pivotal engagement, at least one of said arms and said respective receiver portions and said arms including first electrically conducting portions in electronic communication with said control system;
- and
- at least one of said arms mounted in said respective receiver portion so as to define an open circuit when said at least one arm is at a first position in said respective receiver portion, and defining a closed circuit when said at least one arm is at a second position, where said first electrically conducting portions are in contact with each other.
