Fig. 4: Motion control of the rocket robot in free space and fast actuation in a blood-vessel-like microtube.
From: Micro-rocket robot with all-optic actuating and tracking in blood
a The turning motion of the micro-rocket in 50% glycerol in free space controlled by near-infrared light. The light excites the side face of the micro-rocket to achieve the turning movement. b The relationship between the micro-rocket moving angle and the moving time. Turning of more than 150° is realized within 1.1 s. c Fast motion of the micro-rocket in the microtube. A microtube filled with a 50% glycerol solution was used to simulate a blood vessel. d Instantaneous moving speed and moving distance of the micro-rocket in the microtube
