[Scientific] "Flying Cart"...Stay level even if you push and push.

When moving luggage, it is inconvenient to move if you face stairs or entry prevention stones.

Korean researchers have developed a flight cart that allows humans and robots to interact, enabling convenient cargo transportation.

Reporter Lim Null-sol reports.

The courier busily jumps up the stairs with the box.

It travels a long distance using a chisel, but you have to carry and move it yourself.

However, domestic researchers have developed a "palletron" that can load and transport goods without wheels by placing a multi-rotor drone at the bottom of the pallet that can lift goods.

{팔}'Paletteron' can fly in the direction of human force, unlike conventional drones that operate as pilots or fly with self-driving algorithms.

To this end, a new algorithm was developed and applied, and when a person applies force to a drone, it reads the intention and moves in the desired direction to interact with humans and robots.

[Park Gun-woo / Master of Mechanical Design Robotics, Seoul National University of Science and Technology (first author): Palletron has a force estimation algorithm that distinguishes between the force exerted by a person and the weight of the cargo, and an algorithm called a compliance controller, enabling stable flight according to human force intentions when cargo is loaded.]

In addition, it can load up to 3kg and can be used reliably in places with a lot of shaking, such as stairs and fluffy mats.

While the existing drone is tilted to one side to change its direction, the newly developed palletron maintains parallel even when a person moves directly and can transport cargo.

The research team explained that the drone propeller can be hidden inside and operated safely from external shocks.

[Lee Seung-je / Professor of Mechanical Systems Design Engineering, Seoul National University of Science and Technology: It is expected to function as a new drone that can create a safer and more pleasant environment than when transporting passengers in the future air taxi field.]

The research team plans to continue follow-up research to enable precise work such as piers and wind power generator inspection by adding robot arms as the palletron can be turned in parallel.
