Abstract:
1. A guiding system comprising: a capsule-type apparatus that includes: a position controlling apparatus that includes: wherein the controller is adapted to calculate a drive signal for driving the relative position controlling mechanism, and is further adapted to calculate, based on the calculated driving signal for the relative position controlling mechanism, a gradient signal for causing the second magnetic field generating mechanism to generate the gradient magnetic field for cancelling at least one of inertia force, force caused by wave breaking of a liquid in which the capsule-type apparatus is adapted to float within the subject, and friction force between the capsule-type apparatus and the liquid, when the position of the predetermined axis with respect to the capsule-type apparatus is at least one of moved, accelerated, and decelerated, and wherein the second magnetic field generating mechanism generates the gradient magnetic field based on the gradient signal calculated by the controller thereby inhibiting the capsule-type apparatus from deviating from the predetermined axis.
