Nguyễn Nhật Lâm is still a high school student.

However, he has already achieved wonderful things.

He has made a robotic leg to help people whose natural legs do not work.

It won him a third prize at the Việt Nam Science and Engineering Fair 2018.

For Nguyễn Nhật Lâm, a student at the Nguyễn Huệ High School in the central province of Hà Tĩnh, his favourite place at home is his desk, which is always covered in wires and electrical components.

On this desk, he has conducted many experiments with the aim of creating products that are both helpful and affordable, particularly for the disabled.

Lâm’s latest project, a robotic leg to help those who can’t walk, won third prize at the recent Việt Nam Science and Engineering Fair 2018. The prize is a deserving award for the great efforts and determination of the student from a rural district in Hà Tĩnh Province.

“I have had an interest in machines and electronic devices since I was small,” he recalls. “My house is far from the centre of the district, so I had few chances to come into contact with machinery.

“Fortunately, my uncle had a small workshop nearby. I spent days visiting and watching him work, inspiring me to make my first experiments with electrical items.”

His first experiment was conducted on his own bike when he was in 7th grade.

“I used to cycle about seven kilometres to school, every day. It was such a torture for me to cycle on hot sunny days,” he says.

“I wished I had an electric bike like other kids, but my family could not afford one. Then I came up with the idea of turning my old bike into an electric one.”

The 13-year-old boy embarked on the plan by collecting devices including control boards and batteries, which he attached to his bike.

After nearly a year of assembling and dismantling the components, Lâm finally succeeded in creating his own electric set of wheels. From this first success, he continued to build on his knowledge of software and graphic design via the internet.

Lâm also used his understanding about machinery to fix other villagers’ mobile phones and computers, which provided him with extra funds to purchase more components.

The idea of a low-cost and long-lasting prosthetic leg came to Lâm when he saw disabled people living nearby who had to use expensive and unwieldy artificial legs to get around.

After drawing up his plans and receiving support from his school, he ordered the necessary electronic components from Canada and the US.

It took the young creator 16 months from drawing board to a working robotic leg. His device had two functions – a self-control mode with an electromyogram (EMG) sensor and an automatic mode with an MPU 6050 (magnetic pickup unit speed) sensor. The power is provided with lithium-ion polymer batteries.

“The most important feature of my artificial leg is its automatic mode – when the user walks, the leg will bend or stretch accordingly.

“It is also equipped with an emergency button and GPS system to alert family members when the user encounters problems. When the button is pressed, a message with the coordinates will be sent to relatives’ phones so that they can locate the disabled person,” Lâm explains. “The total cost for my artificial leg is around VNĐ15 million (US$645).”

There were many challenges and failures behind the development of the device, but it was the great support and encouragement of his teachers, friends and family that provided him with spiritual motivation.

“Particularly, teacher Phạm Hồng Dương has always been by my side, helping to order appropriate components on the internet, find disabled people to test the product and offer suggestions for improvements as well as technical support," he says.

“On the night before the provincial contest, the main engine burnt out, but we didn’t give up. We stayed awake until 2am to fix the problem. Finally we succeeded, winning first prize in the provincial creativity contest before entering the national one.

“It was such an honour for me to receive prestigious awards at both the provincial and national contests, which will motivate me for my future creations.”

However, due to a lack of finance and experience, Lâm has not yet thought about registering a patent for his robotic leg or putting it into mass production. However, the young student hopes to realise these ambitions in the near future.

Lâm’s head teacher, Hoàng Thị Kim Oanh, could not hide her pride when talking about her creative student.

“What I admire most is his strong will and efforts to overcome all challenges to fulfill his passion. He has set a good example for every student to follow,” she says.

Before his robotic leg, Lâm’s other project, a laser engraving machine, won second place in the Việt Nam Science and Engineering Fair in the 2016-2017 school year for its advanced features and high applicability.

He was also one of two students in Hà Tĩnh Province to receive honour awards granted for typical examples in the patriotism campaign by the provincial People’s Committee in June.

Thanks to his achievements, Lâm has been admitted to the University of Engineering and Technology under the Việt Nam National University, which he believes will be the next step on his creative journey. VNS


 

 

GLOSSARY

For Nguyễn Nhật Lâm, a student at the Nguyễn Huệ High School in the central province of Hà Tĩnh, his favourite place at home is his desk, which is always covered in wires and electrical components.

Components are parts.

The prize is a deserving award for the great efforts and determination of the student from a rural district in Hà Tĩnh Province.

Rural means to do with the villages, farms and wild areas rather than to do with towns and cities.

 “Fortunately, my uncle had a small workshop nearby. I spent days visiting and watching him work, inspiring me to make my first experiments with electrical items.”

If something is inspiring it makes you do something positive.

“It was such a torture for me to cycle on hot sunny days,” he says.

Torture means terrible pain that is given to someone.

The 13-year-old boy embarked on the plan by collecting devices including control boards and batteries, which he attached to his bike.

Embarked means “set upon”.

Control boards are devices with switches on them.

Batteries are devices that store energy.

After nearly a year of assembling and dismantling the components, Lâm finally succeeded in creating his own electric set of wheels.

To assemble something means to put it together.

To dismantle something means to take it apart.

Lâm also used his understanding about machinery to fix other villagers’ mobile phones and computers, which provided him with extra funds to purchase more components.

To purchase means to buy.

The idea of a low-cost and long-lasting prosthetic leg came to Lâm when he saw disabled people living nearby who had to use expensive and unwieldy artificial legs to get around.

A prosthetic leg is a fake leg.

Something that is unwieldy is difficult to move.

Artificial means “not natural”.

It took the young creator 16 months from drawing board to a working robotic leg.

Robotic means operated by robot.

His device had two functions – a self-control mode with an electromyogram (EMG) sensor and an automatic mode with an MPU 6050 (magnetic pickup unit speed) sensor.

A mode is a way in which something is done.

A electromyogram is a display involving looking at electric activity in the muscles.

A sensor is a device that picks up movements and changes.

“It is also equipped with an emergency button and GPS system to alert family members when the user encounters problems.

Encounters means “comes across”.

When the button is pressed, a message with the coordinates will be sent to relatives’ phones so that they can locate the disabled person,” Lâm explains.

Coordinates are readings that show a location.

To locate something means to work out where it is.

There were many challenges and failures behind the development of the device, but it was the great support and encouragement of his teachers, friends and family that provided him with spiritual motivation.

Motivation is the drive inside a person that makes them want to do things.

“Particularly, teacher Phạm Hồng Dương has always been by my side, helping to order appropriate components on the internet, find disabled people to test the product and offer suggestions for improvements as well as technical support," he says.

Appropriate means suitable.

“Finally we succeeded, winning first prize in the provincial creativity contest before entering the national one.

To be creative means to use your imagination to create things.

“It was such an honour for me to receive prestigious awards at both the provincial and national contests, which will motivate me for my future creations.”

Prestigious means highly regarded and smart.

However, due to a lack of finance and experience, Lâm has not yet thought about registering a patent for his robotic leg or putting it into mass production.

If you register a patent for something you have invented it means that you own it and nobody else may make one and sell it claiming it is their invention.

Mass production means making a lot of something all at once.

However, the young student hopes to realise these ambitions in the near future.

Ambitions are aims.

Before his robotic leg, Lâm’s other project, a laser engraving machine, won second place in the Việt Nam Science and Engineering Fair in the 2016-2017 school year for its advanced features and high applicability.

Engraving means writing or drawing by cutting into a hard surface.

He was also one of two students in Hà Tĩnh Province to receive honour awards granted for typical examples in the patriotism campaign by the provincial People’s Committee in June.

Patriotism is a feeling of serving and loving your country.
