Problem Statement
To create a multiple robot wireless network that cooperatively
searches a given area for a given
object and returns to the central
computer with that object.

Assumptions and Limitations
The robots must be implemented using the LEGO Mindstorms robotics kits.
The central computer must run in the Linux operating environment.
The network will be implemented using infrared communication.
All of the robots should be no greater than 1 square foot in size. The robot network should be able to perform its tasks in a search area of 64 square feet.The robot network should be able to locate a given object.The robot network should not take longer than 60 minutes to complete its task.
