Abstract
In this paper we propose a trajectory control method for a MEMS falling object as shown in Figure 1. The MEMS falling object is consisted of two units, an autorotation part and a non-rotation part. The autorotation part keeps its attitude stable with the gyro-effect of the autorotation phenomenon. The non-rotation part keeps a non-rotation state by using the air breaking boards. This non-rotation part controls its falling trajectory and the scattering region. By using large falling objects, aerodynamics of the falling object was characterized, e.g. falling speed, rotational speed, etc. Then the MEMS falling object was designed considering with this aerodynamics. The MEMS falling object was fabricated with a method of the SU-8 multi-layer structure. A MEMS autorotation part whose wing length is 6mm in diameter rotates at 4,800 rpm in the wind-tunnel successfully.
