15319, 153401, 15356, 15360

An autonomous floor-cleaning robot comprising a housing, a powered wheel drive, a command and control subsystem; and a cleaning head including a deck mounted to pivot with respect to the housing, a brush assembly mounted in the deck and powered to sweep, a vacuum assembly mounted in the deck separate from the brush assembly and behind the brush assembly in a cleaning direction of the robot and powered to ingest particulates during cleaning operations, and a deck adjusting assembly mounted in combination with the deck and the housing that provides lift to the deck, the lift balanced to respond to an increase in brush torque to lift the deck with respect to the housing or floor. The robot also includes a side brush assembly mounted with the housing to entrain particulates outside the periphery of the housing and to direct such particulates towards the cleaning head.

15319, 153404

An autonomous floor-cleaning robot comprises a self-adjusting cleaning head subsystem that includes a dual-stage brush assembly having counter-rotating, asymmetric brushes and an adjacent, but independent, vacuum assembly such that the cleaning capability and efficiency of the self-adjustable cleaning head subsystem is optimized while concomitantly minimizing the power requirements thereof. The autonomous floor-cleaning robot further includes a side brush assembly for directing particulates outside the envelope of the robot into the self-adjusting cleaning head subsystem.

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.

A modular robot development kit includes an extensible mobile robot platform and a programmable development module that connects to the mobile robot platform. The mobile robot platform includes a controller that executes robot behaviors concurrently and performs robot actions in accordance with robot control signals received from the development module, as modified by the concurrently running robot behaviors, as a safeguard against performing potentially damaging robot actions. Also, the user can develop software that is executed on the development module and which transmits the robot control signals to the mobile robot platform over the data communication link using a robot interface protocol. The robot interface protocol encapsulates potentially harmful user-developed software routines from the controller instructions executed by the controller of the mobile robot platform, while nonetheless enabling the user to effectively control the mobile robot platform using the robot control signals of the robot interface protocol.

A power-saving robot system includes at least one peripheral device and a mobile robot. The peripheral device includes a controller having an active mode and a hibernation mode, and a wireless communication component capable of activation in the hibernation mode. A controller of the robot has an activating routine that communicates with and temporarily activates the peripheral device, via wireless communication, from the hibernation mode. In another aspect, a robot system includes a network data bridge and a mobile robot. The network data bridge includes a broadband network interface, a wireless command interface, and a data bridge component. The data bridge component extracts serial commands received via the broadband network interface from an internet protocol, applies a command protocol thereto, and broadcasts the serial commands via the wireless interface. The mobile robot includes a wireless command communication component that receives the serial commands transmitted from the network data bridge.
