Final Project¶
This week I worked on defining my final project idea and started to getting used to the documentation process.
Idea and Sketch¶
I tentatively decide that my final project is “The Beauty of Parting and Reuniting”. All inspiration came from the video I saw below.
From a mathematical geometry perspective, we can easily divide a square into different pieces to make the entire shape look like a Tai Chi pattern. Each small piece of graphics in the divided graphics is connected to adjacent graphics. By rotating the center of the figure, you can see the 8 fragment patterns scattered around the center. After the final rotation, a new hexagonal pattern is formed.
I want to express the concepts of division and union in Chinese culture through the transformation of this mathematical geometric pattern.
In fact, at the beginning, I just wanted to make a desktop ornament to prove the completion of the project. Some of the inspiration needs came from when I went home during the Spring Festival. When I found out that when I returned home, my grandparents were living alone, and there were often things that they couldn’t take care of. The inconvenience of the elderly’s legs and feet will have a certain impact on the elderly’s daily health. In order to better take care of the elderly’s home health, I decided to use some Internet of Things monitoring solutions.
Function Descriotion¶
It seems like I have a loooooot of works to do for this final project.
1. Rotation Clock¶
Functionally, I originally planned this design to be an interactive art clock. It expresses different concepts of time through different positions of the center rotation. It slowly unfolds when the sun rises and slowly closes when the sun sets, thus changing the pattern periodically.
2. People Tracking System¶
Secondly, I need to make a two-axis servo system that can rotate up, down, left and right, as a mobile pan/tilt, to track and locate the position of a moving person, so that the most important sensor always locates the person’s moving position and provides the next posture The positioning function is guaranteed.
3. People Fall Detector¶
Thirdly，for another function, I hope that during the day, when the entire device is turned on, the movement status of indoor people can be detected through the mmwave sensor in the middle, as an anti-fall monitoring function.
4. Remote Alarm Message¶
Finally, the device can send the monitoring results to the cloud or mobile phone to remind people to monitor whether the elderly at home have fallen.
