Figure 16.
The cause of the head-tilt reaction is to suspend the directional changes of the vector field forces acting on the micro-UFO. The head-tilt angle is a parameter proportional to the phase difference. The increase in phase difference also causes an increase in head-tilt angle. As can be seen in the figure, in the experimental studies performed, the head-tilt angle of 7° is displayed. The increase on gradual tilting of the microrobot can be seen in the figure from (a) to (f).
