RESCUE DRONE WITH EXTENDABLE ARM FOR AERIAL ASSISTANCE IN EMERGENCIES

Abstract

The present invention relates to advanced aerial rescue drone, specifically a multi-rotor quadcopter, featuring an innovative arm extension and retraction mechanism. This unique design enables real-time structural adaptability during active flight, allowing the drone to dynamically modify its aerial footprint. By adjusting its size mid-flight, the drone significantly enhances manoeuvrability, aerodynamic efficiency, and overall stability, thereby improving obstacle avoidance, load balancing, and agility in complex environments. also broadens the functional versatility of drones, facilitating effective performance across different applications, including aerial surveillance, inspection, cargo delivery, and other remote operations that necessitate adaptive structural flexibility. The modular arm extension system empowers the drone to operate with heightened precision and control, making it particularly advantageous in scenarios demanding optimized space management and efficient navigation. The drone's dynamic size adjustment boosts effectiveness, making it ideal for missions requiring high responsiveness and adaptability.

Specification

Description:[0013] In the main core and its parts also schematic. As we can see [F.1] denotes the base of the main core on which other parts are fixed and attached with perfect angle and weight. So the base model the drone will be stable. The other parts are such as sensor, flight controller, battery, receiver etc. These all parts are attached to the drone as a normal drone and this mode looking like a normal drone, So the name of this mode is NORMAL MODE. In this normal mode arm and actuators of the drone are completely compressed. Not only the angle between the arms but also the same distance between the motor's. [F.2] denotes the Actuators of the drone, [F.3] is the extension part and Retraction part which are connected to the end of Actuators, [F.4] denotes the drone's motor. The [F.5] is camera module with camera which is placed between the two arms of right side of drone, [F.6] is the angle in which arm will be bend. In this normal mode the stability and the smoothness of the drone are max. Normal mode is smaller with compare to other modes and the same size from each and each side of the drone.
[0014] Figure 2:-It is schematic of main core. In this figure (A.1) denotes the actuators. The (A.2) shows the extended arms of the drone and (A.3) denotes the motor. It is a second type of mode of the drone a POWER MODE. After extends the arm of drone the normal mode converts into power mode. The process of extending arm is depends on actuators of the drone which are connected to the each arm of the drone. Distance between all four motors and the angle between the arm's with compare to other arm's are same.
[0015] Actuators will extends in same speed during extending the arm's. This process not only happen before flight time but also this happens during the flight time. With help of actuators their will possible to convert normal mode into power mode during flight time, because the actuators are work in perfection so their will no any problem in case of balance and stability during flight time. Because of increasing distance from center of drone to motors there is one benefit of payload capacity. Using same energy as before in normal mode, we increase the power of the drone so drone can take more load than before. In this figure 2 the motors of the drone are longer away from the center of the drone as they can.
