Meet the next generation of teachers here in Korea, who require neither food nor sleep.
These colorful and playful robots have been a hit at this elementary school in Gyeonggi-do Province.
Students are captivated as their robotic teachers start classes off with musical songs and also ensure they follow lessons correctly.
"Hey Ki-yeon, did you say 'nevertheless?' I'll read to you slowly."
It's tremendous progress for this special education class as kids have quickly grown fond of their new instructors.
"He listens well and plays together with me. It's been fun studying with Engkey."
This unique class of robots called Engkey was developed by the Korea Institute of Science and Technology.
Researchers specifically designed the robots to help young children with learning disabilities such as autism and ADHD.
After a three-month trial, teachers here say they've seen a dramatic change in their students.
"As we interact with Engkey, there's been a higher desire to make friends and get along with others. And it's not just the learning aspect. I've seen a large effect on the children from their emotional behavior to even their social skills."
The comprehensive system allows a user to remotely control the robot, while closely monitoring students' responses through multiple cameras.
"The robot can be intelligently utilized when children play a game or review material. And when a little more communication is needed, the robot can be remotely controlled. In regard to smart robotics, I believe this attempt to open up a new market in Korea is important."
Ten of the Korean learning robots will be exported to Denmark next year, while additional pilot programs will be conducted here at home, giving schools greater flexibility to reach their students.
