4. Multiple Robot Network Team May 01-164 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.

5. Multiple Robot Network Team May 01-165 Design Objectives Custom software objectives Handle the computer’s communication Handle mapping of the area Interface with the user Robot objectives Uses a microcontroller Communication Programmable Central computer objectives Linux-compatible Available serial port Portable

6. Multiple Robot Network Team May 01-166 End Product Description  Two robots networked with a central computer  Search an area for a given object  Communication between all of the networked devices

7. Multiple Robot Network Team May 01-167 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.
