Room Temperature Operable Autonomously Moving Bio-Microrobot Powered by Insect Dorsal Vessel Tissue
Figure 5
Trajectory measurement of the actual PMR powered by contraction force of the dorsal vessel tissue.
(a) An image of the whole actual PMR after inversion. (b) Enlarged view of the area surrounded by the dotted rectangle marked in (a). A movie of this area was taken for 1 min (Movie S6 in the SI) and analyzed with image analysis. The moving direction was set as the Y axis and the axis perpendicular to the Y axis was set as the X axis, the same as for the prototype. In (a) and (b), the red arrows show the designed moving direction. (c) Trajectories and time courses of moving distances along X and Y axes of the prototypes for the 1 min movie period. The moving distances in the first, second, and third experiments were 199, 256, and 175 µm, respectively.
