Abstract:
PURPOSE: A flying robot using electroactive polymers is provided to reduce manufacturing costs by simplifying the structure of robot and to provide excellent flying performance regardless of flying environment. CONSTITUTION: A flying robot(100) using electroactive polymers comprises a floating force generating unit(140), a main body(120), multiple driving units(110), and propelling units(130). The floating force generating unit floats the robot. The main body is installed in the bottom of the floating force generating unit and comprises a controller. The driving units are installed in the bottom of the main body and are composed of electroactive polymers. The propelling units are installed each end of the driving units.
Abstract:
PURPOSE: A method for controlling bacteria movement is provided to produce bacteria cellulose membrane with fiber structure of even arrangement and uniform thickness. CONSTITUTION: A method for controlling bacteria movement comprises: a step of treating bacteria to attach a reaction unit of charged particle or magnetic particle on the bacteria surface; a step of inoculating the treated bacteria to culture device; and a step of controlling the movement of inoculated bacteria by operating reaction source according to controlling purpose. The used bacteria strain is Acetobacter xylinum.
Abstract:
PURPOSE: A method for controlling movement of growing bacteria through vibration mode shape is provided to have desired arrangement of bacteria cellulose. CONSTITUTION: A method for controlling bacteria movement comprises: a step of inoculating bacteria in a culture device which can implement vibration mode; a step of leading vibration mode shape inside the culture device by applying a specific frequency; and a step of controlling bacteria movement to arrange bacteria along nodal point or nodal line generated by the vibration mode. A method for producing bacteria cellulose comprises: a step of inoculating Acetobacter xylinum in the culture device containing Ph-regulated culture medium; a step of leading vibration mode shape inside the culture device by applying a specific frequency; a step of culturing bacteria controlling bacteria movement; and a step of obtaining arranged bacteria cellulose.
