Mobile robot providing environmental mapping for household environmental control

摘要

A mobile robot includes a processor connected to a memory and a wireless network circuit, for executing routines stored in the memory and commands generated by the routines and received via the wireless network circuit. The processor drives the mobile robot to a multiplicity of accessible two dimensional locations within a household, and commands an end effector, including at least one motorized actuator, to perform mechanical work in the household. A plurality of routines include a first routine which monitors a wireless local network and detects a presence of a network entity on the wireless local network, a second routine which receives a signal from a sensor detecting an action state of one of the network entities, the action state changeable between waiting and active, and a third routine which commands the end effector to change state of performing mechanical work based on the presence and on the action state.

1. A mobile robot, comprising:
a processor connected to a memory and a wireless network circuit, for executing routines stored in the memory and commands generated by the routines and received via the wireless network circuit; driven wheels commandable by the processor to reach a multiplicity of accessible two dimensional locations within a household; and an end effector, including at least one motorized actuator, commandable by the processor to perform mechanical work in the household, the processor executing a plurality of routines including:
a first routine which monitors a wireless local network by communicating with the wireless network circuit, and detects a presence state of one or more network entities on the wireless local network,a second routine which receives a signal from a sensor, the sensor detecting an action state of one of the network entities, the action state changeable between waiting and active, anda third routine which commands the end effector to change state of performing mechanical work based on the presence state and on the action state detected by the first and second routines;wherein the mobile robot processor and wireless network circuit monitor a local wireless network of approximately 5-20 meters maximum range for a change from presence to absence of a known network entity as a departure from the household, and once determining the network entity has departed, waits for a time period to verify departure before initiating a cleaning mission within the household.
