An engineering technician in Hue has created a remote controlled submarine that he hopes could be used for exploration tasks.
Le Nga said he spent nearly two years on making the remotely operated underwater vehicle, commonly referred to as an ROV.
He finished it late last year and successfully launched it down the Perfume River, after several test runs at local swimming pools.
“It was a lot of work to do alone, but it satisfied my curiosity. I got to focus on each single detail, each part until I put together a complete sub.”
The mini-submarine weighs 120 kilograms and is 2.7 meters long, with the body made from cooking gas cylinders of five centimeters thick.
Nga used the engine and controller often seen in model aircraft for his sub.
The 50-year-old works for a beer factory in Hue and is a member of the local model aircraft club.
His mini-sub has a camera at the head and a propeller at the tail that rotates at 10,000 rounds per minute to push it forward.
Mini sub, big plan
Nga said he is still perfecting his remote control and thus is only confident letting the sub dive three meters deep.
He also plans to install a GPS device on the sub and a system to deliver warning signals in case of accidents.
“When the sub works better, I’ll have it dive deeper in rivers and lakes to shoot images… I’ll invite some scientists and officials over for a presentation,” he said.
Russia has delivered Vietnam Geographic Information System (GIS) "Horizon" for coastal missile complex "Bastion" said Tass source in the military-technical cooperation.
