Abstract
Disclosed is a drone. The present invention includes a plurality of propellers creating a lift to prevent inclination and overturn of the drone due to a lift difference generated from uneven ground, a power driving unit providing a rotation power to each of a plurality of the propellers, a ground sensing unit measuring a distance to a first region of the ground and a shape of the first region, and a controller controlling the power driving unit to differentiate rotation ratios of a plurality of the propellers based on the measured distance and shape if receiving an input signal for landing at the first region.
Claims8
A drone, comprising:
- a plurality of propellers configured for creating a lift;
- a power driving unit configured for providing a rotation power to each of the plurality of propellers;
- a ground sensing unit configured for measuring a distance to a first region of the ground and a shape of the first region;
- a controller configured for controlling the power driving unit to differentiate rotation ratios of the plurality of propellers based on the measured distance and shape in response to an input for landing at the first region;
- and
- a variable leg provided to a bottom end of the drone, the variable leg configured to come into a contact with the ground on making the landing and maintain level according to a distance to the ground by withdrawing or inserting the variable leg,
- wherein the variable leg comprises:
- a first shaft;
- a second shaft coupled with a bottom end of the first shaft to be withdrawn or inserted;
- and
- a spring provided between the first shaft and the second shaft.
