Abstract

An aerial system includes a body, a lift mechanism coupled to the body, a processing system, and at least one camera. The aerial system also includes a first motor configured to rotate the at least one camera about a first axis and a second motor configured to rotate the at least one camera about a second axis. The processing system is configured to determine a direction of travel of the aerial system and to cause the first motor and the second motor to automatically orient the at least one camera about the first axis and the second axis such that the at least one camera automatically faces the direction of travel of the aerial system.

Claims

1. An aerial system, comprising:

a body;

a lift mechanism coupled to the body;

a processing system;

at least one camera; and

wherein the processing system includes a rotatable binocular camera system coupled to the body to retract into the body when not in use and to extend above the body when in use to achieve three hundred sixty (360) degree omnidirectional obstacle avoidance, wherein the rotatable binocular camera system includes an inner module, a first spring, a middle module, a second spring, and an outer module.

2. The aerial system as set forth in claim 1 wherein the rotatable binocular camera system also includes push-push socket slot, Hall-effect sensor board, outer block, and a middle block.

3. The aerial system as set forth in claim 2 wherein the middle module includes at least one guiding slider and the outer module includes at least one a guiding slot in which the guiding slider can slide inside the guiding slot, and an upward force is provided through the first spring to achieve the first-stage bouncing/sliding-up.

4. The aerial system as set forth in claim 2 wherein the inner module includes at least one guiding slider and the middle module includes at least one guiding chute and the guiding slider and the guiding chute cooperate with each other to provide an upward force through the second spring and achieve the second-stage bounce with the middle block which provides limit.

5. The aerial system as set forth in claim 2 wherein the inner module includes an adapter board, binocular arm module, gimbal motor, FPC cable and connector, inner bottom, and bent wire hook.

6. The aerial system as set forth in claim 5 wherein the binocular arm module comprises a pair of cameras, a line laser, and a magnet coupled to the body.

7. The aerial system as set forth in claim 5 wherein the gimbal motor includes a motor body, a one-piece FPC, a magnet, and a cover plate.

8. The aerial system as set forth in claim 7 wherein the motor body includes a stator part, a rotor part, and a shift ring.

9. The aerial system as set forth in claim 5 including an automatic binocular lifting structure to move the binocular arm module up or down relative to the body.
