What is a Robot?
Our technology advances tremendously in the past few decades, so does the capabilities and the intelligence of the robots. As a result, there’s no fixed definition of “robot� today. Many roboticist and dictionaries have their own definition that varies from one another. However, there are still some general guidelines that people agree on: A robot is a physically embodied artificial intelligent machine that can perform complex tasks autonomously. Some robots may be constructed to take on human form but most robots are machines designed to perform a task with no regard to how they look.

Technology Trigger
Peak of Inflated Expectations
Trough of Disillusionment
Slope of Enlightenment
Plateau of Productivity
New technology emerged, but are still concepts with a few prototypes. There is no product in the martlet yet.
The technology is implemented and gained a lot of media attention. Both successful and unsuccessful news are reported.
The outcome of the technology is not as good as expected. The failures cause some producers to drop their product.
Producer finds new potential for further application of the technology. Producer moves on to create 2nd and 3rd generation product.
The technology is widely implemented in the market. People fully understand the technology and use it in their daily life.
My Future Robot’s Technologies Virtual Customer Assistant
Deep Learning
A virtual customer assistant is a computer program that assists customers. It can help guests with simple questions, guide them to places, recommend them some nearby tourist places or restaurants.
Deep learning automatically learns representations from data such as images, video or text, without introducing hand-coded rules or human domain knowledge. It can be used to recognized crime, learn the map, communicate in multiple languages and more.
Rollable Display
Facial Recognition
A rollable display, also known as a flexible display, is a type of screen that can be rolled up like a scroll without the image or text being distorted. If it is implemented on the robot, the overall form of the robot can be more flexible.
A facial recognition system is a technology capable of identifying or verifying a person from a digital image or a video frame from a video source. With facial recognition, the robot can unlock door for people who locked themsleves out of their room, and greet people with their names.
11
Wireless Power Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to an electrical load without interconnecting wires. By incorporating Resonance Charging into my robot, it allows smaller battery size, thus the size of my future robot can be significantly reduced.
12
Inductive Charging
RF (Radio frequency)
Inductive charging is typically used for medium sized devices such as a few different types of smartphones, tablets, and MP3 players. Devices are placed on a wireless or conductive charging pad.
Radio frequency wireless charging technology utilizes radio frequencies to charge a device. RF wireless charging is somewhat similar to wifi in that it uses radio frequencies to transmit energy from a wireless charger to receiver within a similar device, that is then converted into electricity.
Resonance Charging
Ultrasound
Resonance charging is used for devices such as a large computer, electric car, vacuum cleaner, or robot. Resonance charging involves a copper coil which is attached to the device that requires charging with another copper coil attached to a power source.
The uBeam wireless charging project involves the conversion of electricity to sound. Once it is converted, it is transmitted through the air using ultrasound. A receiving device then captures the ultrasound waves and converts them back to an electrical current.
Uncanny Valley The “uncanny valley” is a characteristic dip in emotional response that happens when we encounter an entity that is almost, but not quite, human. Anything with a highly humanlike appearance can be subject to the uncanny valley effect, but the most common examples are androids, computer game characters and life-like dolls
Example video: https://youtu. be/732C-F3_fys
Jerky and Mechanized Motion
Unsettling Electromechanical Sounds
It is very eerie when the emotional expression looks mechanical. The contractions of the facial muscles are fake and it cannot fool a human’s eye. The unnatural abrupt pause in the robot’s motion and the mismatches of its lips and voice are creepy.
Kawada HRP-4, is a very tall and skinny robot, so it is programmed to walk slowly and carefully. When it walks, there is an unsettling mechanical noice in every steps it makes. This sound and its large size make it feel threatening to human.
Example video: https://youtu. be/GrQ9c5hmbFE
Eyes without a focus
Gender-specific
In the video, the android has very realistic eyes that can blink normally like a human’s eyes. However, the eyes do not focus on the user while it is having a conversation. It stares like a pair dead eyes. The eyes are empty, and you don’t feel life in those eyes.
Jia Jia and Erica are both female humanoids that are made to be the most beautiful andriods in the Chinese and Japanese society. In many videos I watched, there is a higher percentage of female bots compared to male bots. It can send a wrong message that women are bound to serve in the hospitality industry.

DFMA Guidelines DFMA, Design for Manufacturing and Assembly, is a methodology that combines Design for Manufacturing (DFM) and Design for Assembly (DFA). It is used to minimize product cost through design and process improvements.
1. Reduce Parts
3. Standard Components
2. Modular Design
4. Multifuctional Parts
The reduction of the number of parts is the best way to reduce manufacturing costs. Less parts implies less purchases, inventory, handling, processing time and more.
Modular design simplifies manufacturing activities such as inspection, testing, assembly, purchasing, redesign, maintenance, service, and so on. Modules add versatility to product update in the redesign process and allow the use of standard components to minimize product variations.
Standard components, “off the shelves� parts, are less expensive than custom-made items. It is often produced in large quantities thus it is reliable and can reduce product lead times.
Using parts that serve multiple functions reduces the total number of parts in a design. Thus reduces the production cost. Some examples are a part as both an electric conductor and as a structural member, or parts that have guiding or aligning features to facilitate assembly.
25
Top-Down Assembly
5. Multi-use Parts
8. Minimize Assembly Directions
6. Ease of Fabrication
9. Maximize Compliance
In a manufacturing firm, different products can share parts that have been designed for multi-use. These parts can have the same or different functions when used in different products.
Selecting the most suitable material and manufacturing processes can minimize the production cost. Final operations such as painting, polishing and finish machining should be avoided.
All parts should be assembled from one direction, ideally top down direction. This would make it easier for workers to assemble (with the help of gravity) thus reduce the production time.
Including compliance in the part design and in the assembly process can help to aviod error during the insertion operations. Use tapers or chamfers and moderate radius sizes to facilitate insertion.

10. Minimize handling
flexibility
Handling including positioning, orienting, and fixing a part should be minimized to reduce chances of error. Symmetrical parts should be used when ever possible.
Fastening and Joining
Mechanical fastening
Welding
Welding (Plastic)
Advantages: No bonds are formed between materials. Parts can be disassemble without causing damage. Common Types: Threaded Fasteners: bolts, screws, studs, setscrews - Can be easily removed and reused. Permanent Fasteners: rivets - Rivets are generally used to hold plates or sheet metal together.
MIG Welding - Simple to learn and widely used in the industry but works with limited materials TID Welding - Aesthetically pleasing and highly precise but steep learning curve Stick Welding - Very strong welds and is good for thick materials
Hot Plate Welding - Inexpensive process used to bond simple but large parts Vibration Welding - Fast and accurate. No marking of show surfaces Spin Welding - High quality permanent joints, hermetic seals, lower equipment costs compared to other processes
Brazing & Soldering
Adhesive
Brazing - Involves a filler metal that has a liquidus above 840°F (450°C) - Brazed joint is strong, and is use to join dissimilar metals. It also has a smooth appearance. Soldering - Involves filler metals with a liquidus of 450°C or below - Typically results in a lower-strength joint than a brazed joint
Cyanoacrylate (superglue) - Instant bonds used for light assembly with good environmental resistance. - Bonds metal, thermoplastic, rubber, and wood. Epoxy - Mainly use for industrial applications like automotive industry. - Bonds prepared metals, thermoplastics, foam, wood, primed glass, and prepared rubber.
Urethane Adhesives - Provide the highest performance and have the greatest versatility Anaerobic Adhesive - Bonds without the pressence of heat, oxygen or even light

Snap Fits
Adhesive
Screws
I decided to use snap fits as my fastening method for the main body plastic housing.
I decided to use adhesive to adhere the screen to the body.
I decided to use screws to fasten the main body to the metal base.
Reasons: - Those parts do not need to come apart. - Adhesive provides a permanent joint. - Provides better and cleaner appearance than other joining methods.
Reasons: - Strong and reliable bond. - Can be disassemble for infrequent maintenance or recycling. - Long lasting and resistant to corrosion.
Reasons: - Easy to disassemble for maintenance. - Snap fits has a lower production cost. - Easy to assemble, thus lower labor cost and higher manufacturing efficiency.

Future Robot Manufacturing Process
OLED ink-jet printing
Metal 3D Printing
Inkjet OLED printing has the desirable ability to allow precision deposits without the use of a mask. It also produces less stray particles, thus boosting yields. https://www.oled-info.com/
Metal 3D Printing allows for the direct manufacturing of complex end-use parts and facilitates tooling for conventional manufacturing technologies, reducing costs and lead times.
Why? Current OLED producing method causes a lot of waste and is expensive. Inkjet OLED printing have the potential to increase yields and lower prices. Thus it is a possible solution to make scalable OLEDs for the future.
Why? This technology combines the design flexibility of 3D Printing with the mechanical properties of metal. It will be a common manufacturing process in the future.
FDM (Fused Deposition Modeling) FDM Technology works with specialized 3D printers and productiongrade thermoplastics to build strong, durable and dimensionally stable parts with the best accuracy and repeatability of any 3D printing technology. Why? FDM uses real materials, as opposed to photopolymers. The potential for new FDM materials is greater, as the tech is not constrained to materials that must be cured via UV.
