WATCH THIS LIQUID ROBOT SHAPE SHIFT

Researchers at Seoul National University have created a liquid-particle composite called a Particle-armored liquid roBot (PB) can deform, engulf, and merge without losing its structural integrity, enabling it to perform functions that are difficult for rigid robots, according to Hyobin Jeon and colleagues. The PB is an important step toward miniature machines that behave more like cells, the researchers say, with potential biomedical applications such as tumour cell destruction and drug delivery.⁠
