1. A landing gear control apparatus for an air mobility vehicle, the apparatus comprising:
a shaft deployed when the air mobility vehicle is landing or driving;
a tire provided at one end portion of the shaft;
a steering rod coupled to the shaft in a direction crossing a longitudinal direction of the shaft to steer the tire by rotating the shaft;
a rotation load sensor mounted on the steering rod and configured for detecting a rotation load applied to the steering rod;
a magneto-rheological (MR) damper being coupled to the shaft to surround the shaft, having a MR fluid filled in the damper, and configured for changing a damping force of the MR damper for rotation of the shaft according to a current applied to the MR damper;
a controller electrically connected to the rotation load sensor and configured for controlling the current applied to the MR damper according to the rotation load detected by the rotation load sensor; and
a driving device,
wherein the steering rod includes:
a first link, a first end portion of which is connected to a rotation shaft of the driving device wherein the driving device is configured to steer a driving direction of the air mobility vehicle by rotating the first link when the air mobility vehicle drives;
a second link, a first end portion of which is pivotally connected to a second end portion of the first link; and
a third link having a first end portion pivotally connected to a second end portion of the second link and a second end portion connected to the shaft, wherein the third link and the shaft are integrally rotated with respect to a central axis of the shaft with rotation of the second link.
