Remote weapon system and control method thereof

A remote weapon device comprising:

• a firing arm configured to fire a bullet at a target in response to a firing signal;
• a driver coupled to the firing arm and configured to move the firing arm to aim the firing arm at the target;
• a detector configured to detect shaking of the firing arm with respect to a zero position, the shaking caused by a plurality of bullets being fired from the firing arm, the zero position corresponding to a position at which the firing arm points at the target and fires the bullet at the target, each bullet generating a partial shaking pattern after each bullet being fired;
• and
• a controller configured to obtain a shaking pattern based on the detected shaking overlapping the partial shaking pattern of each bullet and configured to generate the firing signal controlling a firing time when the firing arm fires the bullet according to the shaking pattern to control the firing arm to fire the bullet,
• wherein the shaking of the firing arm is generated from firing of bullet by the firing arm, and
• wherein the controller is configured to obtain the shaking pattern of the firing arm over a predetermined time while the firing arm fires the plurality of bullets.
