The drone that can climb walls

Researchers in South Korea have developed a drone that is capable of climbing walls.

Thrust generated from the drone's rotors allow it to stick to the wall, while its wheels allow it to move around.

BBC Click's Jen Copestake visits the Urban Robotics Laboratory at the Korea Advanced Institute of Science and Technology (KAIST) to find out more.
