This paper presents a micro liquid prism. Two flat transparent plates float on a liquid droplet and these plates serve as prism faces. The two plates are positioned automatically by surface tension, just by putting the plates on the ellipsoidal droplet. Therefore the proposed prism can be fabricated accurately in micro scale without difficulty. As the liquid and the plates are encapsulated by Parylene,...
This paper presents a scanning micromirror using deformation of a parylene-encapsulated liquid structure (PELS). Silicone fluid is put between a silicon plate and an electrode-patterned plate. Both of the plates and liquid are encapsulated by a parylene membrane. Gold is deposited on the surface of the parylene membrane to fabricate an upper electrode. By applying voltage between the upper and lower...
This paper proposes a switched visual feedback control method for a micro helicopter under occlusions. Two stationary cameras are placed on the ground. They track four black balls attached to rods connected to the bottom of the helicopter. The control input is computed by using the errors between the positions of the tracked objects and pre-specifled reference values for them. The multi-camera configuration...
This paper proposes an image-based visual servo control method for a micro helicopter. The helicopter does not have any sensors to measure its position or posture on the body. A stationary camera is placed on the ground, and it obtains image features of the helicopter. The differences between current features and given reference features are computed. PID controllers then make control input voltages...
