  • Cambodian students have designed a prototype drone that they hope can eventually be used to move people around Phnom Penh and even help fight fires.
  • 2
  • The drone was developed by students at the National Polytechnic Institute of Cambodia (NPIC), a college in the capital city.
  • 3
  • The drone has eight propellers and uses a school chair for the pilot's seat.
  • 4
  • Lonh Vannsith, age 21, recently piloted the drone.
  • 5
  • "The drone, when we see it flying without a pilot, there is a lot of shaking, but when I sit on it and fly... it becomes more stable and I feel so excited," he said.
  • 6
  • Excited is a term that means very happy or enthusiastic about something.
  • 7
  • Vannsith added that the group of students "wanted to solve some problems for our society by making a taxi drone and... inventing drones for firefighters."
  • 8
  • He explained that the drone could reach the upper floors of a building to bring a hose if a fire truck could not reach the area.
  • 9
  • The prototype can carry a pilot weighing up to 60 kilograms and fly for about 10 minutes for a distance of 1 kilometer.
  • 10
  • It took three years of research and development, and it cost around $20,000 to build.
  • 11
  • The drone currently only rises as much as 4 meters, but the team hopes it will eventually fly far higher.
  • 12
  • The project faced delays because of coronavirus restrictions.
  • 13
  • Parts for the drone had to be purchased from abroad, said Sarin Sereyvatha.
  • 14
  • He is NPIC's head of research and development technology.
  • 15
  • The team plans to improve the design to permit it to take more weight and fly farther and higher.
  • 16
  • "In principle, if we make one drone, the cost is expensive but if we make them to sell on the market, the cost will go down," said Sarin Sereyvatha.
