Abstract

These days, among many people who use computers, few people know how computers work. We have a critical mind about this situation and have produced a mechanical logic gate to solve it. As part of STEAM education, it aims to help people, especially elementary school students, intuitively understand logic operations, the basic principles of computers. We succeeded in making logic gates using 4Dframe that are easy for elementary school students to handle. When using 4Dframe, you will be able to intuitively understand logical operators.

Abstract

The 'Magician of Painting and Infinite Space' project was planned as a 4-session program to enhance the mathematical and artistic capabilities of middle school students through the works of M.C. Escher, a printmaker who combined mathematics with art. Students understand Escher's motivation for using convergence materials, and directly produce 3D optical illusions and tessellation learned through the work with 4Dframe. Finally, by allowing them to create their own work, this project aims to improve students' challenging spirit, creative thinking, and cooperative ability based on abstract expression and spatial perception.

Abstract

Balance is the key for a clown to perform above heights. Balance is important to keep the body from wobbling and safe. This project aims to develop a clown stay in the high place using the implementation of the hanging masses and pully belt system. The balancing clown innovation was developed using 4D frame figures, waste bottle caps, and cardboard. This innovation is divided into 5 development sections: towers, bridges, pulleys, unicycles, and clown bodies. The 4D frame has succeeded in realizing a balancing clown that can move forward and backwards without falling with mathematical analysis, such as diagonals, the circumference of a circle, an inverted pendulum, pulleys, and loading..

Abstract

This capstone is made to summarize the progression Pulse has made throughout its journey in making its wave generator machine so that it can demonstrate the physical relations between mechanical transverse wave and their corresponding formulae used to quantitatively assess them. Pulse hopes to demonstrate these phenomena intuitively through the prototyping of multiple wave devices, having started with moving motors and then going to a more streamlined design inspired by Da Vinci’s flying machine. Through this avenue, carefully refined programming of the Arduino, and careful picking of the tautness of string, we should be able to demonstrate standing wave with great efficiency. Along with creating a device that makes a standing wave, we hope to create a story with a pedagogical focus that will create interest in children aspiring to become future STEAM innovators by tying the same design to other wave phenomena in space. Along in this capstone, we demonstrate our process of making not only this device but also the challenges and lessons that were learned to create our final project. Pictures and schematics will be included below as we discuss the creation of Pulse’s Wave Generator.

Abstract

Since the mid 1970’s we have had rovers on other surfaces communicating through hundreds of kilometers with a satellite. The aspects of these two communication systems are key in the understanding of everyday life. We have developed a rover communication system that allows for us to remotely control the rover and receive information. While creating the concept, we knew that there were multiple aspects we wanted to be featured. Our biggest priority was to demonstrate the fundamental concept of using signals to communicate. We accomplished this by attaching a transceiver to our computer and another to the rover. This shows the communication of earth's satellites to the rover on another surface. Satellite communication is something that we use everyday. When we make a call, the signal is transmitted to the satellite and then to the other phone. This is the same concept we wanted to demonstrate.

Abstract

As the importance of environmental preservation is emphasized day by day, the need for water quality exploration is also increasing. The water quality exploration robot built with 4Dframe can be active in various water resource areas by reducing the cost for professional water quality exploration. The aircraft is composed of the 4Dframe as a framework and is driven using the motors and mainboard of the 4Dframe mechatronics. In addition, by using a long-distance data transmission sensor using the AP function, the water pollution level can be investigated with low power. In this final report, it was concluded that efficient research would be possible in the future through water temperature and PH measurement using the sensor.

Abstract

This work is a combination of wind power generation, software, 4Dframe, and modular house. There are three features. First, it is easy to expand or reduce the house with partial modularization. Second, it can move not only in back and forth, but to all directions. Third, since it is difficult to express wind power generation using 4Dframe, making a bird model and flapping its wings generates wind power, which turns the windmill and generates electricity for the modular house and mecanum wheel to promote activities with eco-friendly energy

Abstract

Probability exists everywhere in the world around us and plays an incredibly important role in our everyday lives. From a simple coin toss to the billion dollar casino industry, probability is essential across many fields, professions, and even recreationally. Mastering the concept of probability can be extremely beneficial, so an Automatic Card Dealer was created as a tool to help illustrate, teach, and practice probability. In the design, a joystick and LCD screen are used to simplify the card selection process and two motors are used for dealing the cards. Once the team finalised the design for the system, a frame was constructed and built and individual electrical subsystems were tested. After these subsystems were programmed and tested to ensure functionality, they were combined and tested as a single system. During the development of the project several issues were encountered with the LCD, stepper motor, and joy stick. Through both hardware and software debugging, several iterations of our subsystems and full system were created in order to achieve a functional final product. This final product provides a fun, yet educational way to introduce any age to the world of probability.
