Autonomous floor-cleaning robot
First Claim
1. An autonomous floor-cleaning robot, comprising:
- a housing infrastructure including a chassis;
a power subsystem for providing the energy to power said autonomous floor-cleaning robot;
a motive subsystem operative to propel said autonomous floor-cleaning robot for cleaning operations;
a control module operative to control the said autonomous floor-cleaning robot to effect said cleaning operations; and
a self-adjusting cleaning head subsystem including a deck mounted in pivotal combination with said chassis, a brush assembly mounted in combination with said deck and powered by said motive subsystem to sweep up particulates during cleaning operations, a deck adjusting subassembly mounted in combination with said motive subsystem for said brush assembly, said deck, and said chassis that is automatically operative in response to a change in torque in said brush assembly to pivot said deck with respect to said chassis, and means coupled to said brush assembly for collecting particulates swept up by said brush assembly.

Abstract
An autonomous floor-cleaning robot comprising a housing infrastructure including a chassis, a power subsystem; for providing the energy to power the autonomous floor-cleaning robot, a motive subsystem operative to propel the autonomous floor-cleaning robot for cleaning operations, a command and control subsystem operative to control the autonomous floor-cleaning robot to effect cleaning operations, and a self-adjusting cleaning head subsystem that includes a deck mounted in pivotal combination with the chassis, a brush assembly mounted in combination with the deck and powered by the motive subsystem to sweep up particulates during cleaning operations, a vacuum assembly disposed in combination with the deck and powered by the motive subsystem to ingest particulates during cleaning operations, and a deck adjusting subassembly mounted in combination with the motive subsystem for the brush assembly, the deck, and the chassis that is automatically operative in response to an increase in brush torque in said brush assembly to pivot the deck with respect to said chassis. The autonomous floor-cleaning robot also includes a side brush assembly mounted in combination with the chassis and powered by the motive subsystem to entrain particulates outside the periphery of the housing infrastructure and to direct such particulates towards the self-adjusting cleaning head subsystem.
