ML-based Weather Forecast on Raspberry Pi
Fu Zheyu, Qi Zhenting, Chen Xuanyu, Yuan Chenzhi
Weather forecasting is crucial in our daily lives. It allows us to make proper plans and get prepared for extreme conditions in advance. However, meteorologists always get it wrong half of the time. To overcome the limitations of traditional weather forecasting, machine learning models have become increasingly important in weather forecasting. Building our own weather forecast ML system is a perfect idea for us to analyze vast amounts of area data and generate more accurate and timely weather predictions on the go in our surrounding areas.
A solution generated by Fu Zheyu’s team mainly consists of two parts. For weather measurement and data collection, temperature, humidity, and barometric pressure sensors are considered the main components. A machine learning-based algorithm is to be applied for data analysis and weather predictions. This weather forecasting system can accurately collect climate data such as temperature, humidity, and barometric pressure, and can predict weather conditions in real-time through machine learning algorithms.

An Intelligent Assistant Using Sign Language
Liu Hanwen, Zhou Yike, Lou Haina, Chen Qianzhong
Recently, smart home accessories are more and more common in people's home. A center, which is usually a speaker with voice user interface, is needed to control private smart home accessories. But an interactive speaker may not be the most ideal for people who are hard to speak or hear. Therefore, Liu Hanwen’s team aim to develop an intelligent assistant using sign language, which can understand sign languages, interact with people, and act as a real assistant.
The bionic hand can move free and fluently as designed. The movement of single joint of the finger does not interrupt or be interrupted by other movements. The durability and reliability of the bionic hand is achieved. Also, the edge computing platform they choose have high performance when running the dynamic gesture recognition model, and their machine could recognize different sign language immediately and react with corresponding gestures without obvious delay.
Best Mechanically Designed
Robotic T-Shirt Launcher Mark II
Xiao Ziyu, Guo Moyang, Ding Hao, Guo Yixiang
Xiao Ziyu’s team has identified a problem with the launcher project that was completed last year, which only included a single-shot launcher that required manual reloading and could only adjust the angle and direction automatically. To address this issue, their team has proposed an improved design that is a fully automated system capable of launching multiple T-shirts by itself, without manual reloading. Their proposed design also includes more advanced features, such as the ability to adjust the trajectory of the launch. In addition, they build it into a wearable device that could be carried on the shoulders.
The launcher can launch T-shirts accurately and consistently at a controlled angle and velocity, and the entire launch process and angle control can be initiated and controlled by a single button. Also, the launcher is designed with safety mechanisms, such as emergency stop buttons, to prevent accidents or injuries.
Instructor's Choice
High Noon Sheriff Robot
Zhang Youcheng, Xu Yuan, Shao Shuting, Pan Yilve
Nowadays, with global public safety issues facing severe challenges, the security upgrade of public places urgently needs to be improved. Inspired by the American western movies, Zhang Youcheng’s team has developed a robot that can detect potential threats and pull out weapons first in order to warn the criminal to abandon the crime or use non-lethal weapons to take him down if he continues to pull out his gun.
In order to achieve effective protection in a legal manner, they proposed the idea of safety robots, which can quickly detect dangerous individuals and fire non-lethal ammunition to prevent dangerous events. This type of robot can move quickly and open weapons at the first time when human life and health are threatened and carry out accurate shooting. If the opponent surrenders, the robot will return the gun to its original position.

Digital Controlled LED Rotating Display System
Fu Guanshujie, Shen Keyi, Jin Yichi, Yuan Chentai
Fu Guanshujie’s team aim at developing a digital controlled LED rotating display system, where a servo motor is controlled to drive the stick with one row of LED to do circular rotation. By visual persistence phenomenon, any images and strings can be displayed with a rotating LED array. However, there are some common issues to be solved. First, the images or strings to be displayed are pre-defined and cannot be changed in a real-time way. Second, the wired connection between some components may limit the rotation behavior, and harm the quality of display.

The connection between LEDs, control circuit, motor and other components should be simple but firm enough to suppose good display and high-speed rotation. Moreover, there is another part to handle users’ input and communicate with the display part via Bluetooth to update images in a real-time and wireless way. In the system, the motor can drive the LED array and any necessary components to rotate stably and safely, guaranteeing that the LED array is under real-time control and responds rapidly.
