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.
Claims15
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;
- and,
- 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 second end, 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 a floor or surface over which said nozzle traverses.
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;
- receiver portions configured for receiving said arms in a pivotal engagement, at least one of said arms and a respective receiver portion 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, where said first electrically conducting portions are out of contact with each other, and, defining a closed circuit when said at least one arm is at a second position in said respective receiver portion, where said first electrically conducting portions are in contact with each other.
