Abstract
An electromagnetic coil system for driving control of a micro-robot includes pairs of X-axis and Y-axis Helmholtz coils whose winding central axes are placed on an X axis and Y axis respectively, a position recognition system that detects a position and direction of the micro-robot in a workspace, a controller that controls an amount of supply of electric currents flowing to the X-axis or Y-axis Helmholtz coils in order to control movement of the micro-robot based on information about the movement of the micro-robot and previously input information about a path of the micro-robot, and a current amplifier that supplies the electric currents to the respective Helmholtz coils. The pairs of X-axis and Y-axis Helmholtz coils are disposed so as to face each other, and the X-axis Helmholtz coils and the Y-axis Helmholtz coils are vertically crossed and installed so as to form the workspace of the micro-robot.
