They can also be used to navigate complex environments for applications like disaster relief by detecting signals indicating signs of life. Unfortunately, there has been no origami microrobot that can operate efficiently both onground and in-water, and most physiological environments are complex and wet in nature. Additionally, most origami microrobots need multiple components to perform more challenging locomotion and functions.
In a recent paper accepted by Nature Communications, a team of researchers led by Professor Renee Zhao, Dr. Qiji Ze and Ph.D. student Shuai Wu, in the Department of Mechanical Engineering at Stanford University, reported a spinning-enabled amphibious microrobot that can be wirelessly controlled by magnetic fields for integrated capabilities of multimodal locomotion, delivery of liquid medicine, and cargo transportation. Figure 1 demonstrates the controlled delivery of liquid medicine in an ex vivo pig stomach.
“The design of the robot comes from the effective rotational motion that enables both onground rolling and in-water propelling. This work exploited geometrical features of the millimeter origami robot and its foldability for amphibious locomotion and delivery of liquid medicine,” says Zhao.
