Emirati students from various schools and colleges made a statement at the Expo Sciences International (ESI) 2019 held at Abu Dhabi National Exhibition Centre.
The largest event in the UAE that focused exclusively on the scientific creativity of students from all over the world attracted 2,000 participants from 57 countries. And hundreds of local aspirant scientists drew attention of thousands of visitors with their various innovative projects.
Automated fueling of vehicles, all-weather jacket for workers, ropes made out of plastics and sustainable cities of future were some of the hundreds of projects on display by Emirati students.
The promising show by the local wizards during the week-long exhibition was icing on the top of a highly successful journey into the space by the UAE.
The exhibition was held by the Abu Dhabi Centre for Technical and Vocational Education and Training.

Visually-impaired walk unaided with Falcon-X
Three boys from Fujairah have made a special multi-use glass for visually impaired, which will alert the user for any obstacle in front of them.
"Falcon-X can detect obstacles like wall, door, car, people etc using an ultrasonic sensor and then it beeps or vibrates. We want visually-impaired be self-dependent and walk without any assistance. The system alerts the user if there's irregular heartbeat and condition is serious.
Whenever they sense danger, they can send SMS to their parents and four other mobile numbers by pressing a button on the glass," said Ali Adel Aldhannani, Khameis Al Zeyoudi and Hassan Jamal Aldhannani, students of Hamad bin Abdullah Al-Sharqi Secondary School from Dibba Al Fujairah.
"They used Arduino UNO, wires, batteries, buzzer, pulse and ultrasonic sensors, vibration motor to make this project," supervisor Mohamed Selmi Mohamed said.
A tool to make space mission more efficient
Mahra Wesam Al Sayegh, an aeronautical engineering student at Khalifa University Abu Dhabi, has devised a system to make space journey more efficient by decomposing water molecules in their gaseous state as a fuel to launch a rocket into space.
She has named her space shuttle Al Abra - the traditional boat.
Mahra's project works on the theory of using hydroxy gas - a combination of hydrogen and oxygen produced from the electrolysis of water - to accelerate the engine faster while consuming less fuel.
"A space shuttle burns half-a-million gallons of liquid propellant provided by external fuel tank but the engine's exhaust is primarily water vapour. Formation of water vapour slows down the functioning capacity of the engine. I thought of making this work to our advantage. Al Abra will use water vapour to have its engines accelerate. This will not only lead to less consumption of fuel, faster speed, acceleration of engine but also raise efficiency of the space shuttle," she said.
Smart Mirror that tells everything
Three girls from Ras Al Khaimah made a Smart Mirror that can give updates about weather, stock market, news, social media notifications, alarm etc while used at home, or flight updates if installed at airport washrooms and more such services.
Maryam Mohammed, Eiman Jassim, Layla Taleb from Al Hudaiba Girls Secondary School said their Smart Mirror is a hi-tech home décor with all needed details.
"This will make life easier for everyone. We have used Raspberry Pi single-board computer and Python programming language. There is a camera installed in the mirror, which will be used for face detection. We need Wi-Fi connection to make this work. This can be used at malls, airports and police stations, but different models for different places. It can be easily carried anywhere. We will make further upgrades on this," the trio said.
Solution for parents who lock children inside vehicles
Two Dubai-based students have created a system, which will send warning messages to parents when children are locked up in their vehicles. "We have read lots of media reports about children forgotten inside the car, leading to deaths. When a child is left locked inside a car, the first 10 minutes are very crucial as the temperature rises rapidly. Since there is no effective way to have parents avoid forgetting their child in a car or stop them from doing it, we have come up with a solution," Emirati duo of Ibrahim Ahmad and Hussain Ghadoub, students of Higher Colleges of Technology, said.
"We used motor and CO2 sensors for this project. Our system will be installed below the car seat. Once a child is forgotten inside a car and the CO2 level rises considerably, the windows will automatically be lowered enough to allow supply of fresh air. At the same time, an SMS alert will be sent to the parent. Also, if any parent leaves child intentionally inside the car and wants to lower the window, they can do that with a missed call to the system."
The duo has tried the system successfully and hopes to find sponsors to roll it out for public use.
Empowering people of determination
Girl students from Madinat Zayed in Abu Dhabi developed a self-directed wheelchair for people of determination to use at hospitals.
"The electric wheelchair uses infrared sensors for its movement. You see there are guiding lines on the floor of hospital with different colours, like yellow one will take people to X-ray department, blue line to laboratory etc. We use infrared sensors to read the guiding lines and transfer patients accurately. We use ultrasonic sensor, which will help detect any obstacle in front of the wheelchair and stop immediately. There is also cushion to support their head, neck and back," Fajr Yousif Alhammadi and Shaikha Ali Alhammadi from Applied Technology High School said.
"We run this on simple car batteries and with motor. We have successfully tested this wheelchair with the help of Arduino programme," they added.
