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.

When looking at the container library donated by The Dariu Foundation at his schoolyard, Cuong Tran, 14 years old, told his classmate Phu Nguyen that he wished the container library were movable, so that they could move it from school to school. They decided to develop a movable house as their summer project. Micro:bit is used as the central controlling system to connect and control other external sensors such as lighting, humidity and proximity, and motor servo. A light sensor is used to transfer a signal to the Micro:bit for automatic lighting; a humidity sensor is used for watering, and pumping; a motor servo is utilized for opening/closing the main doors. “Our dream was to make a house that’s able to fly like a drone,” said Cuong Tran.

School toilets often has three problems: electricity and water waste and smoke (illegal smoking)
by students. Our group developed a Micro:bit-based project to solve these problems.

The system has two functions:

1. All fans and lamps are connected to motion sensors, and the ventilation and lighting system
   are only switched on when the users move.
2. Cigarette smoke sensors are installed in the restrooms, and as soon as smoke is detected, the alarm goes off and sends an alert to the manager at the same time

Future upgrade: Our team would like to upgrade the water supply with hand sensors so that water only flows when users put their hand to the faucet. At the same time, the water runoff from the sink will be used to irrigate the school garden.

All the patient’s information, such as blood pressure, pulse etc. are monitored and appear on the screen, next to the bed. The system sends a warning signal to the attending doctor/staff, if any of these stats are irregular and/or of concern.

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.

We have noticed at our school that students leave their classrooms without turning off the lights and fans and leaving the doors open. This leads to a waste of electricity. Therefore, our team decided to develop a project where the lights and fans are automatically switched on and off and the classroom doors are closed or opened via I.o.T.
In all public areas, the lighting is set to turn on and off at a specific time, based on daylight sensors. In the classrooms, the lights and fans are switched on and off at a specific time and according to lesson times. The fans are also set to turn on and off based on the temperatures in the classrooms via temperature sensors.
Additionally, we installed movement sensors: when there is movement, the sensors send signals to the computer centre to turn on the lights and fans and to close or open the classroom doors.

The natural crab population is decreasing while the market demand is increasing. Crab farms face several problems in raising crabs as they can kill each other due to high density during the period of shell molting.

How does it work?
The farm is divided into small tubs to prevent the crabs from killing each other. The water supply to the farm is controlled by solubility sensors to ensure that only qualified water enters the farm.- The system is equipped with other sensors to provide water at an appropriate temperature to help the crabs reproduce. Light and humidity sensors, as well as solar panels, are installed to help farmers control their farm in a smarter way.

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.

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.

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.
