Once the robot is exposed to acoustic waves of around 330 kHz, the air bubble pulsates, pushing the liquid inside the tube towards the back end of the microrobot. The liquid's movement then propels the bullet forward quite vigorously at up to 90 body lengths per …
WebIn cases in which the bubble/microrobot are oriented along the interface, the resulting propulsion is parallel to the interface and results in a greater velocity. We observe that the relatively slower microrobots appear to reside somewhat below the bubble and therefore a component of the force likely pushes the microrobot downward from the ...
