Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
158 words
A system for automatically operating a robot within a working area comprising: at least one indicator positionable to define the boundary of said working area; and a robot comprising: a sensor adapted for detecting said indicator; a processor in operative communication with said sensor, said processor programmed to: initially generate a map of said working area in accordance with at least a substantial traversal of said working area along a path corresponding to the position of said at least one indicator; and correct the position of said robot in accordance with said generated map when said at least one indicator is reached; a locator configured for determining the coordinates of said robot relative to an arbitrary origin at any specific time; memory for storing values generated by said processor; a direction finder configured for determining the direction of travel of said robot; and a motion controller configured for causing said robot to move in a substantially continuous manner.
Claim 2
Independent Claim
158 words
A system for automatically operating a robot within a working area comprising: at least one indicator positionable to define the boundary of said working area; and a robot comprising: a sensor adapted for detecting said indicator; a processor in operative communication with said sensor, said processor programmed to: initially generate a map of said working area in accordance with at least a substantial traversal of said working area along a path corresponding to the position of said at least one indicator; and correct the position of said robot in accordance with said generated map when said at least one indicator is reached; a locator configured for determining the coordinates of said robot relative to an arbitrary origin at any specific time; memory for storing values generated by said processor; a direction finder configured for determining the direction of travel of said robot; and a motion controller configured for causing said robot to move in a substantially continuous manner.
Claim 3
Dependent Claim
18 words
The system of claim 1 , wherein said at least one indicator includes at least one metallic wire.
Claim 4
Dependent Claim
41 words
The system of claim 1 , wherein said processor is additionally programmed to: activate said robot and cause said robot to move to a position corresponding to at least a portion of said boundary defined by said at least one indicator.
Claim 5
Dependent Claim
15 words
The system of claim 1 , wherein said robot additionally comprises a lawn mowing system.
