autonomous robots gradually expand their fields, our daily lives are getting easier. Now, they are also sent to hospitals to deliver medicines, helping nurses.



Reporter Ki-tae Kim took a look at how far the core technology of autonomous driving has come.



<Reporter> A



robot loaded with medicine from the hospital's dispensing gate calls the elevator without human help to board the elevator, and automatically opens the automatic door to pass through.



The robot, which started on the 4th floor, delivers medicines to the nurse waiting in the ward on the 5th floor.



[Jeon Joo-heon / Yangji Hospital Head Nurse: I often have to spend time going to the pharmacy, so if the drug delivery robot brings it at that time, I think it is efficient because the ward can do other tasks at that time.]



5G-based autonomous driving technology This is the combined drug delivery robot, 'Medibot'.



The Medibot, which is 130 cm high and runs at a speed of 1 m/s, returns to the charging area by itself when it finishes its work.



During the movement, the security system works, so you cannot open the drawer unless you are a medical staff.



[Park Kang-soon / LGU+ Platform Business Team 2 Team Leader: I paid attention to stop and return if there is an obstacle in the middle so that there is no inconvenience for patients to move around the hospital… .]



Separately from the floor plan, the Slam technology, which is used as a basis for judgment when moving by creating an indoor map, ultrasonic sensor and lidar technology that works when recognizing and avoiding obstacles are applied. These are core technologies that are also used in autonomous vehicles.



Security patrol robots that identify and handle fire or crime situations by applying this technology, and robots that deliver food are also used in everyday life.



However, the core of autonomous driving technology is data accumulated on the road. Compared to Tesla with 5 billion miles and Baidu with 10 million miles, our company's driving mileage is only 12,000 miles, so it is evaluated that there is still a long way to go.
