1. 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.
