AI and 3D printing

●Conception

The original conception is to present all the circumstances of Tianmu life which are our life experiences. The members of our team have many information technology capabilities, and the teacher can guide us with the information specialty. Later, we come up with the idea of performing a drama with robots and using 3D drawing to design the buildings in Tianmu. Except for the living circumstances in Tianmu, we can also present the articles that we design to allow everyone better understand Tianmu.


●Equipment and material

Kebbi AIR robot, SONY AIBO mechanical dog, iPad, DV, camera, Phrozen Sonic mini photocuring 3D printer and resin.


●Production and design method

Robot Reader's theater:With Kebbi AIR robot and SONY AIBO mechanical dog, controlling the voice and action by programming blocks, arranging proper background, and producing the films of little theater by the camera.


3D printing architecture:We use Google map to observe the change of buildings by adjusting the age, and present the characteristics of building by 3D printing. As tiny details are required in the design of architectural model, we use Photocuring to print the architectural model. The software of 3D drawing is called TinkerCAD. We design while cooperating with the switch of street view and time line of Google map, and even go to the site to directly observe every aspect and appearance of the architecture. At last, we make it to a 3D picture and print it with a 3D printer.


●Key points of the research process

Robot Reader's theater:During the research of robot programming, as we have learnt similar concepts in the information course of Grade 5, such as Scratch and Micro:bit, and the teacher has taught the basic programming concept of Kebbi AIR in the previous course, including light, voice and action design, we are familiar with the operation. The difficult part is the synchronization of the dialogue time of two robots. We tried a long time to find out a set of rules, e.g., the calculation of number of words or action of every sentence, and the corresponding waiting time. In addition, the design process of script consists of discussing the role definition (name, identity, etc.) of robot and scenario aiming at the theme, designing the respective scripts by all the members on the site, discussing every dialogue in the script, and integrating a set of complete script.


3D printing architecture:3D printing is not a new thing to us. We have many experiences of production in both the information course and the course of Cyberfair project, such as making bookmark, storage box, luminous ball, and fingertip top. Most members have the experience of over one year. The teacher has told us that there are many repeated elements in architecture. For example, except for the first floor and the top floor, most of the floors between them are similar. We can find a pattern before the production to save a lot of time. In addition, we can use the deletion method to skip over some details or hidden parts for the ease of design.


●Difficulty and effectiveness

The most difficult part is to synchronization of robot dialogue time and the design of script. The design of 3D architecture is not difficult. What is difficult is the subsequent printing as the printing support must be taken into consideration. Sometimes, we meet the problem of printing failure, but we can correctly complete as long as we pay more attention to the details. At last, we print another copy of 3D printing architecture that we design to the boss of the construction company accepting the interview. It can be not only used in the competition but also as an exquisite interview gift in return.

●Brief introduction of Kebbi AIR

Kebbi Air is featured with STEAM program education, theater English learning environment and physical interaction education. Famous English education courses such as Live ABC, Ivy, Sesame Street, Xu Wei English, are built in, and new class outlines and the single-word course required by primary school English examination are also loaded exclusively to improve children's learning motivation by lively single-world study, daily dialogue, English story and animation.

At present, Kebbi Air can identify more than 300 daily supplies, and perform by switching over a hundred roles and body operations to accompany children to explore and learn. Except for serving as an attendant accompanying the children in study, Kebbi Air is also an AI intelligent helper assisting to family as it can play the music and report the weather by Google Assistant voice control. If further connected the app of NUWA ROBOTICS, it can make phone calls, video calls, or remote control.


●Brief introduction of Sony AIBO

AIBO is the first electronic robot pet introduced by SONY Corp. in 1999. The appearance of AIBO not only represents the birth of robot pet. What is more important is that AIBO combines the technology of AI and develops towards the orientation of life entertainment. SONY also make great efforts in naming AIBO. The name contains several meanings: AIBO is the pronunciation of "companion" in Japanese, and "Eye-Robot" in English. The letters of A and I in AIBO are the abbreviation of Artificial Intelligence.

There is a tiny chip in the body of AIBO that endows it with smart features, and allows it to make various interesting actions like a real dog, such as fishtailing and rolling. It also knows to distinguish whether people are calling or blaming it. In the chip, the process of its growth is set. And the robot dog can learn by itself. If you get along with him for a long time, it will remember your sound, action and appearance, and know who you are. Especially, if you are good at programming, you can design some new actions for it, such as fishtailing and rolling.

●3D printing architecture

●Brief introduction of 3D printer

3D printing is also called stereoscopic printing. Additive manufacturing can refer to any process of printing 3D objects. 3D printing is mainly a process of continuous addition when raw materials are added under computer control. The contents of 3D printing can come from 3D model or other electronic data, and the 3D object printed can have any shape or geometric characteristic. 3D printer is one of industrial robots, and the word of "3D printing" originally refers to the process of depositing the materials to the powder-layer ink-jet print head in order. recently, the meaning of this word has been expanded to various technologies, such as extrusion and sintering process. The term of "additive manufacturing" is generally used in technical standards to express this extensive meaning.

At present, two most commonly used 3D printing technologies are FDM and SLA/DLP/LCD.

FDM is the most common 3D printing technology. The raw materials of 3D printing are usually the thermoplastic polymer transmitted on the scroll bar, which is generally called wire rod. The raw materials are extruded by the heated nozzle installed on the shifting bar, allowing the materials extruded by the nozzle to stack layer by layer in within the printing area, be cooled and solidified on the platform to complete the object. Advantages: It is easy in operation and maintenance. Compared with other 3D printing methods, the price is cheaper. It is easy to keep the environment clean. No extra chemical is required to be used. The equipment is small so that it can be put on the table. The whole process goes inside the machine, requiring no extra equipment. There are many optional materials, with engineering characteristics. The equipment price is relatively low, which is conducive to shorten the product delivery time. Disadvantages: There are usually stacking lines on the surface. The printing quality affects the physical strength of the finished product.

●Brief introduction of photocuring 3D printer

The technology of Photocuring is used in our work. The raw material of liquid resin is poured in the resin tank, and the printing platform is immersed in it. Then, illumination plane or laser UV irradiates the beam to the printing platform. The resin will be hardened and shaped up after being radiated to mold by stacking layer by layer as the platform is lifted from the resin tank. In particular, there are many different abbreviations, such as SLA, DLP, and LCD, because of different illumination technologies, but the technical principles are much about the same. In the aspect of industrial precision, SLA is superior to DLP and LDC, but the price is also much higher. The most affordable LCD technology only takes about NTD 8000. SLA is suitable to be used in complete parts or jewelry design with precise details. Supporting structure is required to be used in almost all the circumstances, and it can be used in small studio or technical laboratory with good ventilation. Compared with FDM, the after-treatment of SLA is more complex. Generally, alcohol is required for cleaning, or it should be put into UV box as required for additional irradiation in order to reinforce the solidification. The raw material of resin is pungent and inflammable, and the storage life is comparatively short. Old and new resin cannot be mixed for use. and the price is higher than the other technologies. However, the surface of the finished product based on SLA is the smoothest, suitable for the prototype of delicate modeling objects or small parts.
