Two students from Le Quy Don Specialized High School (Quang Tri) designed virtual reality (VR) software to provide a new and engaging learning experience.

Traditional methods often lack the visual appeal and interactive elements that resonate with young learners. In addition, some schools lack the resources to set up well-equipped laboratories or conduct certain experiments due to cost constraints. e-Lab steps in to fill this gap.

e-Lab simulates labs and classrooms for various subjects in a 3D environment and VR technology. Users can move, observe, manipulate and experiment with realistic experiences that represent elements that cannot be observed in the real world. e-Lab is built with outstanding features:

• Observe and interact with invisible quantities (force vectors, types of substances, etc.).
• Interact with objects at the cellular, molecular, and atomic levels
• Perform dangerous experiments or recreate objects that cannot be reproduced under normal classroom conditions
• Integrate an artificial intelligence virtual tutor to deliver lectures and answer students’ questions by voiceWhen users put on the glasses, they are transported to a virtual laboratory. In this virtual lab, chemical experiments, physical phenomena, or biological phenomena inside cells can be demonstrated.

Students in Hau Giang Province have developed a smart dryer for tea leaves and other medicinal herbs,
that is controlled by a smartphone and integrates IoT technology.

Responding to the growing demand for natural remedies, this project aims to:

• Empower individuals: The compact design allows for home and personal use, making it accessible to a wider audience.
• Improve control: Users can monitor and manage the drying process remotely via their smartphone.
• Improve efficiency: The automated system saves labour and simplifies the drying process.
  The model included a wood and foam drying house, a Yolobit circuit, signal cables, a DTH20 sensor for temperature and humidity, a fan, a pump, LED lights, an LCD screen, a servo motor for the door and a fire alarm system. This intelligent dryer facilitates the remote control and management of electrical appliances, especially when users are not at home, offering labour-saving benefits and a modern dryinand a modern drying experience.

Our town often faces the risk of severe flooding, with water suddenly pouring down from the
stream, causing substantial damage to homes, disrupting electricity and water supply. Therefore,
we developed the floating house to solve those problems.

How does it work?

The house can float on the water when the flood happens, by using water level
sensors. The rain is also collected into the storage for daily use, especially during the flooding days.
Furthermore, the house has a garden to grow vegetables, controlled by automatic watering systems and uses solar panels for electricity supply. By using IoT technology, it can all be controlled remotely.

It has been proven that drones are being used more and more frequently in rescue operations and are becoming increasingly helpful and effective. For example, when a fire breaks out in a residential building located in narrow alleyways in cities.
A drone can help transport fire extinguishing balls, masks or other equipment to support rescue operations. During firefighting operations, the drone is also used to identify people in need of help in areas that are difficult to access, rooms or tall residential buildings or in smoky areas.

The camera streams live images to the control screen, allowing the rescue team to create different and effective plans for rescue operations. The drone is designed to carry two fireballs at a time. It uses camera and heat sensors to detect fire, and the user can control the dropping of the fireballs.

The drone can also be used for other rescue missions; for example, to transport water, food, milk or other supplies to assist rescue teams.

An intelligent robot designed for use in hospitals and high risk isolation areas.

How does it work?

The robot is equipped with an arm, a storage compartment and a navigation system, and is controlled by WiFi navigation.

When something needs to be transported to a specific area/room, hospital staff place the item on the tray and enter the destination. The robot then travels to the designated location and notifies both the recipient to pick up the items and the sender that the items have been delivered. Along the way, it can also pick up other items, as long as they have the same destination.

The notifications are sent to the users/senders via a Telegram account.

In agriculture, seed preservation plays a vital role in ensuring optimal plant growth and maximizing yields. Vietnam’s hot and humid climate poses significant challenges when it comes to storing seeds. In response to this issue, we propose a smart cabinet that is able to control air quality, humidity, temperature, prevent mold and unintended germination. This project aims to simplify seed preservation for farmers, using the internet of things: data is collected, processed and updated to https://www.adafruit.com via micro:bit.

How does it work?
UV light runs for 10 minutes daily to disinfect and prevent harmful bacteria and mold while fans adjust air circulation based on temperature sensors installed inside the cabinet. A dehumidifier activates when humidity is low and temperature and humidity data is regularly updated via an app on a tablet. Alerts are sent to users via the Telegram account if conditions exceed standard levels.

Severe winters lead to the death of animals, livestock and poultry in villages, resulting in loss of income and investment for farmers. Our team proposed a project to build a community shelter, equipped with modern technology to reduce cold-related deaths.

How does it work?
We install sensors – to measure the outside and inside temperature – and heating systems. The indoor temperature is automatically adjusted to provide heat to the indoor station.

We also install automatic feed doors to provide food and water to the animals at specific times.

Last but not least, we install automatic cleaning and chemical spraying systems for the station. At the end of each day, the cleaning system will operate to clean the station, and spraying approved chemicals to protect the animals from diseases.

One of the goals of the technological revolution is to make life more convenient.
Smart homes allow us to live comfortably without having to worry about cooking, brewing coffee, ironing laundry or wasting electricity. Everything is automated. For this reason, our team has decided to build a Smart Home that fulfills some of these requirements.

How does it work?
Energy saving: Motion detection turns the light on and turns it off when there is no movement and it reduces light intensity when sufficient daylight illuminates the area.
Security: There is a sound alarm for incidents such as fires, earthquakes and flashing lights, indicating that an intruder enters.
The door locks and unlocks with a passcode.

Sturgeons require moderate temperatures for ideal growth and ample supply of clean water.
Local farmers often use stream water from high mountain, for which it is difficult to control the cleanliness/
clarity of supply water. Therefore, they spend a lot of time controlling the water supply manually. Our team offers a smart solution for this problem.

How does it work?
Sensors are installed to measure the cleanliness/clarity of the water. At a previously fixed level, the valves will be opened to supply water into the pool of
sturgeons. If the water is not clear, the valves will remain closed. If the valves are closed for a certain period of
time, the system will send an alarm to the farmers, so that they
can find a different source of water supply for the fish pools.
