Abstract
A method and system for propelling and controlling displacement of a microrobot in a space having a wall, includes the steps of: forming the microrobot with a body containing a magnetic field-of-force responsive material, wherein, in response to a magnetic field of force, a force is applied to the material in a direction of the magnetic field of force; positioning the microrobot in the space for displacement in that space; and generating the magnetic field of force with a predetermined gradient and applying the magnetic field of force to the microrobot propelling the microrobot through the space in a direction of a field of force. Then, a sequence of field generating steps are executed, wherein each step includes calculating the direction, amplitude and spatial variation of the net field of force to control displacement of the microrobot in the space and against the wall from one equilibrium point to another.
