Background: The tedious process of floor cleaning has become a menial, labor
demanding, and time consuming task, which can be accomplished without an
overwhelming amount of skill. We have realized that people at home are too busy for
daily or weekly floor cleaning, especially for families with children. The elderly who
lives by themselves do not have the strength or ability to clean by themselves, and the
cost of hiring a maid is expensive. Out in the industry, nightly office cleaning almost
always includes vacuuming of the floor which takes efforts away from other cleanups or
becomes an entire person’s task. Labor costs are expensive and quickly adds up. We
believe an autonomous robotic vacuum cleaner can help by automating this task. A
robotic vacuum can vacuum a floor space on its own without the help of anyone. And the
cost of using one has a fixed price rather than paying an escalating price on workers. The
device has to be simple enough for any adult to use. For this product to succeed, it needs
to do its job well by covering the entire floor space in a timely fashion.



The Design: The following are descriptions of the design.

              The design and building of a working prototype in seven months.
              The parts required to build the prototype to cost no more than $500.
              Require service of four engineers to design, program, and built the robotic
               vacuum.
              The robotic vacuum will primarily be for office use where light-carpet and
               tile floors are used.
   The floor spaces where the robotic vacuum will vacuum are assumed to be
    clear of objects where all furniture is to be against a wall.
   The robotic vacuum should have an ordered process of vacuuming a room.
   It should vacuum a floor space without going over the same spot
    repeatedly.
   The robotic vacuum must be as lightweight as possible so it is portable for
    use in different locations.
   The battery used to power the robotic vacuum must be last for at least 45
    minutes.
   The user interface should be simple to use. It should include an indicator
    to tell how much battery power is left.
   The maintenance required should only be charging of its battery and
    change of its cleaning bag.
   The robotic vacuum should operate over the range of temperatures and
    humidity normally found indoors.
   The robotic vacuum will not be designed for outdoor use.
   The tests involved to demonstrate the robotic vacuum’s abilities should be
    done under various conditions where floor space is of different size and
    shape.
   The failure rate of a production model should be no more than once per
    three years.
