| Research Abstract |
In this research, micro robot which is composed of piezo elements and electromagntes is designed and the special micro hopping tool is implemented onto the small robot to provide micro indentation with the accurate spacing. Ad s the results of the primary experiements, the feasibility of micro modling process performed by the micro robot system is confirmed with the seceral unique results. In 2001, the mentioned below issues were investigated,
(1) Design and fabrication of micro hopping tool with diamond indentor :
For avoiding the additional actuator, the hopping tool which is supported by the simple cantilever mechanism can be excited by the stepping motion of the micro robot.
(2) Implementation to the micro robot and experiement
The resonating micro hopping tool was implemented on to the micro robot and the micro machining were carried out on the surface with a diamond indentor of 0.5 micro radius tip. As a results of the experiment, the micro dip of 1 micron diameter were successfully indented with the spacing of 4 micro.
In 2002, the issues were considered for checking the possibility of micro molding by micro robots ;
(1) Melted metal injection :
The solder which was heated up by the coil heater is injected to the target by the solenoid inertia injector and the micro melted metal can be pasted. Then another small robot with the micro heater can weld the metal dip to the surface.
(2) 2 dimentional micro groove machining :
The hopping robot can make the small groove by controlling the spacing to be narrow and then the precise groove can be feagured out on the target which is set on the other small robot moving perpendicularly. This two small robots combination can allow the 2D micro grooving with the depth of 0.2 micron.
