Amphibious Magnetic Origami Robot

Millimeter-scale origami robots are being developed for medical applications, but most require separate parts for movement and function. They also struggle to operate in both air and water. This project introduces an amphibious origami millirobot, a small, magnetically controlled device that moves and performs tasks without wires.

Inspired by Kresling origami, a hollow, foldable shape, this robot uses its structure for multiple functions. It moves by rolling, flipping, or spinning in different environments. Its folding and unfolding mechanism pumps liquid medicine, while its spinning motion allows it to transport small solid objects. This combination of movement and task performance make the millirobot useful for minimally invasive medical treatments. It can be controlled inside the human body to deliver medicine to targeted areas, minimizing the need for wide spread medicine distribution.
