The requirements of the completed system are as follows:

 · Chassis of sufficient strength to accommodate a    total loaded weight of 100 pounds.

 · Sufficient self-contained power supply (battery)    capacity to power the robot for a
   minimum of 1 hour.

 · Modular power supply and distribution system to    allow regulation of battery voltage down to    standard voltages including 12V, 5V, and 3.3V.    The power distribution system shall also include    voltage monitoring and fusing to prevent damage    to components.

 · Motor drive allowing forward motivation at typical    human walking speed (5 mph), reverse direction    capability, and in-place turning (zero turn radius).

 · Ability to navigate in the building using floor    surface feature recognition; i.e. line tracking    using identification of floor tile color.

 · A hardware kill switch in case of undesired robot    behavior.

 · Use of standard interface protocols, in hardware    and software, including Ethernet, serial, and    UDP.

 · Modular, expandable, and well documented    design of all hardware and software to facilitate    feature addition and maintenance. A complete    software application programming interface (API)    shall be delivered to allow higher level software to    interface with sensors and motor control

 · Use of common components with other robotics    teams to facilitate maintainability share common    development achievements
