    • The present invention relates to a micro robot control apparatus using magnetic sensors. The apparatus includes a direction control coil unit having first and second circular coils of the same radius coaxially spaced apart from each other and generating a uniform magnetic field region in some areas of the spaced space to control the direction of a micro robot within the magnetic field regions of the first and second circular coils; a power supply unit supplying a current value of the same current direction to the first and second circular coils to form the uniform magnetic field region; first and second magnetic sensors spaced apart from each other outside the first and second circular coils to detect the first and second magnetic field strength; and a current amount control unit controlling the power supply unit to maintain the current value previously supplied to the first and second circular coils if the difference between the first and second magnetic field strengths is within an error range, or to control the current value of the first or second circular coil if the difference is deviated from the error range. Therefore, it is possible to compensate the magnetic field strength, which is caused by the disturbance, by the values detected by the magnetic sensors disposed outside two circular coils, and to form the further uniform magnetic field.

    • PURPOSE: A task management device using an array-type task scheduling table of a real-time operating system and a management method thereof are provided to comprise the task scheduling table that the operating system refers for a context switch as an array, thereby improving real-time performance of the operating system. CONSTITUTION: A memory(20) stores tasks by comprising a task scheduling table(21) which is fixed by using arrays in a constant area. When one task is executed in an operating system, a microprocessor(10) stores a current task in the task scheduling table by determining generation of a context switch and executes a next task by reading the same. A specification of each task is assigned to the task scheduling table.
