Problem Statement Project: Autonomous Robotic Vacuum Cleaner Advisor: Professor Mark Preston Team: Eric So Joaquin Ajtum Ying Moy Yueh Lan Quach 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.
