Technologies
360 * Camera
Voice Command
A.I.
Mobile App
Motion Activated
Taking 360* picture or video recordings where a view in every direction is recorded at the same time, shot using super wide angle cameras or a collection of cameras. Current robot vacuums only have sensors so adding 360* camera can give them a wider view of the space, and it can map out the rooms.
Voice control is a device controlled by means of the human voice. By removing the need to use buttons, dials and switches, consumers can easily operate appliances with their hands full or while doing other tasks. Telling robot to vacuum the house while eating dinner with the family saves time and energy.
Is the ability of a computer program or a machine to think and learn. It is also a field of study which tries to make machines “smart”. Over a period of time, robot vacuum will learn when it’s time to vacuum the house. When the owner isn’t home. When a mug falls on the floor and breaks.
Is a computer program designed to run on a mobile device such as a smart-phone or tablet computer Keep track of how often you let the robot vacuum the house. Use the app to set automatic cleaning when you are away.
Is a device that detects moving objects, particularly people. Such a device is often integrated as a component of a system. Built-in motion activated camera lets the robot knows when the user is in the room. If the user is in the room the robot move on to another room and let the user rest in silence.

Technologies
Self-driving
Solar Panel
Is a vehicle or device that is capable of sensing its environment and navigating without human input. The robot vacuum senses the environment around it and avoids stairs, obstacles, or pets.
Absorb the sunlight as a source of energy to generate electricity or heat. Houses with open windows can recharge vacuum robot using the sun light.
Quang Nguyen
Silicon-Air Battery Silicon–air battery technology is based on electrodes of oxygen and silicon. Such batteries can be lightweight, with a high tolerance for both extremely dry conditions and high humidity. The lightweight battery will reduce the load on the motors.
Drone
Pet Interaction
An aircraft without a human pilot aboard. The flight of UAVs may operate with various degrees of autonomy: either under remote control by a human operator or autonomously by onboard computers. Adding drone capability to robot vacuum so it can reach high places like on top of the cabinet, skylight, or air vents.
The above device is Pet Chartz, it allows people to talk with their pets while they are away. It also has the treat dispensing feature. Most people bought robot vacuum due to the shedding of pet hair. Adding the technology that lets the owner interacts with their pet.

Manufacturing Processes
CNC Milling
3 D Printing
Sand Casting
CNC Milling is the machining process of using rotary cutters to remove material from a workpiece by feeding in a direction at an angle with the axis of the tool. Great for precision parts for the internal components.
3D Printing is a process of making three-dimensional solid objects from a digital file. Difficult to manufacture parts can be 3D printed.
Sand Casting is a metal casting process characterized by using sand as the mold material. Great for heavy duty parts.
13
Super-forming Super-forming is a high temperature strain rate controlled gas pressure forming process. The process can achieve highly complex shapes in sheet or tube and can incorporate tool movement to achieve features undercut to die-line. Thin metal pieces good for housing.
Thermal Forming A sheet of plastic material is heated to plasticity, then pressed against a 3D mold by vacuuming out the air between the sheet and the mold, and applying air pressure above the plastic sheet. Housing of the device.
DSID128 FA17
Manufacturing Processes
Investment Casting
Injection Molding
Die Casting
The mold is formed by using a wax pattern - a disposable piece in the shape of the desired part. Tiny internal components can be casted.
Is a manufacturing process for producing parts by injecting material into a mold. Injection molding can be performed with a host of materials mainly including, elastomer, confections, and thermoplastic and thermosetting polymers. High volume and complicated parts.
Is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. High volume metal parts can be produced using die casting.
Quang Nguyen
Sheet Metal Is metal formed by an industrial process into thin, flat pieces. It is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Thin metal sheet can be shaped into structure parts.
Chemical Etching Is the subtractive manufacturing process of using baths of temperature-regulated etching chemicals to remove material to create an object with the desired shape. High precision process, great for etching or creating thin metal parts.

Persona Name: Veronica Family Age: Veronica 32, Ricky 12 and Josie 8. Status: Single mom Location: Seattle, WA Occupation: Financial Consultant, $60k Interest & Hobbies: yoga, jogging, reading, going to the museum, handcrafting gifts, painting, playing poker. Pets: 1 cat and 1 dog. Bio: Veronica was born in Seattle and had lived there for most of her life. She works as a financial consultant for Affirma Consulting in Seattle. Her daily schedule can take up most of her day and it’s difficult for her to get everything organizes within a day. Currently, Veronica has 1 cat and a dog, and they love playing with her kids. However, they shed hairs faster than Veronica can clean them. “Okay, I am in need of an automated robot cleaner that doesn’t require my attention to operate. It must require little maintenance, clean under the furniture, and transport my only cat around. I know he is lazy!”
25
DSID128 FA17
Key Goals Little Maintenance: Remove hairs on the roller, clean the wheel, or replace the batteries.
Getting Corners: Ability to clean corners and wall edges.
Low Profile: Gets into tight spaces, between chair legs, and under furniture.
Efficient: Wider cleaning area in a small package.
User and Pet-friendly: Easy to operate and can be a pet’s best friend. Mission: Existing robot cleaners are restricted by their plastic housings, narrow brush sizes, and non-swappable batteries. They are chunky, limited in the cleaning area, and have short cleaning time. My mission is to design a new robot cleaner that will celebrate the functionality, wider cleaning area, and longer running time.

G etting the Corners
2 1 3
This area focuses on different ways to clean corners: 1. Flies - the two front heads move extended out to clean the corners. 2. Pac-Man - when it gets near a chair leg. It opens out like a Pac-Man so it can clean around the leg. 3. Dream Catcher - the internal components are held by bungee cord which reduces the vibration and noise. 37

6 This area focuses on low profile and small footprint: 4. Skii - this design is like skiing, the both pedals come closer when it senses narrow space. 5. Earth & Moon - this design is small, the outer brush rotates around to collect dust and the middle brush collect the rest. 6. Antenna - the front brushes push dirt toward the center and go straight into the dirt bin. Quang Nguyen

This area focuses on large clean area: 7. Tick - many side brushes push dirt to the center of the dirt bin. 8. Walking - this design has two brush heads and two different dirt bins. It can clean in a straight line or side way. 9. Meiosis - the head brush is oscillating so it can move left or right, and it can reach under low furniture. 39

11 12 This area focuses on “what-ifs”, meaning what could it be like in the future: 10. Origami - the dirt bin is folded when it’s empty and when it’s full the dirt bin expands out. 11. Paper Ball - it uses kinetic power to walk and the feet clean the surface. The dirt bin is at the center. 12. Spiral - the spirals are silicone and it picks up dirt. When it’s full it can be rinsed off and reused. Quang Nguyen
