Spinning-enabled Wireless Amphibious Origami Millirobot

Stanford researchers at the Zhao Lab have developed a wireless, magnetically actuated amphibious origami millirobot that can locomote in narrow spaces and morph their shapes. The researchers have demonstrated that this millirobot can travel on surfaces and through liquid. Please see news article and videos below.
This robust and multifunctional untethered millirobot integrates capabilities of spinning-enabled multimodal locomotion, controlled delivery of liquid medicine, and cargo transportation. This invention can be used as minimally invasive device for biomedical diagnoses and treatments such as atherosclerosis and targeted drug delivery.
