A research team in Korea has created a robot that can run fast on a sandy beach where it is difficult for humans to walk.
When the terrain changes, it even has the ability to move accordingly.
This is TJB reporter Jang Seok-young.

A robot with four legs walks slowly on a sandy beach.
After a while, the robot slowly picks up speed and runs without hesitation, creating a sandstorm.
This is the quadrupedal robot 'Raibo' developed by Professor Bo Jemin Hwang's team at KAIST.
Laibo operates freely on various grounds, such as air mattresses and sandy beaches, as well as on hard ground such as grass and running tracks.
[Choi Soo-young/PhD student at KAIST Department of Mechanical Engineering: If you go to a soft place or a place where your feet fall out like this, you will lift your feet higher.
In the meantime, robots have been able
to avoid obstacles or go down stairs, but on sand or gravel, the shape of the floor changes in various ways and the posture becomes unstable, making it difficult to walk. It is.
The research team introduced an artificial neural network structure used for artificial intelligence and AI implementation.
Twelve sensors attached to each joint of the leg collect data such as pressure when stepping on the ground, analyze and predict it through a trained artificial neural network, and take action.
It walks at a high speed of 3.03 meters per second on the beach sand, and can rotate 90 degrees per second on an air mattress.
[Hwangbo Jemin/Professor of Mechanical Engineering at KAIST: We need data to train artificial neural networks.
The data is obtained through simulation.
Then the (learned) artificial neural network enters the actual robot and controls the robot.] Since the
quadrupedal robot can perform various tasks such as military use, logistics transportation, factories, and pet use, the research team is engaged in mass production research for commercialization of the robot. plan to focus.
