Summary of the invention
[0002] Copter with coiled arms is a combination of copters and robotics. The feature like coiling arms connected to the copter helps differentiate it with other family of copters. Coiling the arms is a basic technique to overcome some disturbances occurring due to extra features like arms; using the wiring mechanism it is also easy to control the arms attached to the copter, due to its compact size and shape it looks small and also occupies less volume resulting in good efficiency. In this design the arms will get close to the body resulting in better centre of gravity also results in good manoeuvring ability, the coiling mechanism is simple and runs with a motor, the drone can move in crucial places where the wind is high because of compact body.

[0003] Arms connected on both the sides of the copter helps lift the body by holding it; the threading mechanism attached to the holder which placed at the tip of the arm chain uses to either holding or releasing the body this cabling system is operated by a single servo motor which also connected to the power system with the help of wires, this wire will pass through the centre line of the arm to avoid deflection to arm chain; As the arm is made up of light weight and tuff material it can hold little heavy objects.

[0004] The arms attached to the main body of the copter can move front and back to hold the body parallel to the forward direction this can be controlled by the pair of cables provided one on either side of the cable that is responsible for the holding of the object, these cables can be moved with the help of two servos connected one to each cable, this mechanism helps to move the arms front and back when the main body in rest or motion.

[0005] The coiling mechanism helps many problems solve and one of them is landing gear in a design when extra features like arms are attached to the body, this helps conservation of materials which helps in the case of manufacturing and also have many applications in defence and can also be used as a rescue drone; it is totally worked with a single motor place beside the system one to each of the arm chambers.

[0006] The whole system of arms is placed at the centre of gravity of the copter which helps in the better performance of the drone.

[0007] As the whole mechanism consists of only simple electronics only a few amount of energy is consumed by them so there is no requirement of additional power source to operate the arms; by this design we can expect the results that are given by a complex design so this can be a simple useful design.

[0008] High definition cameras that can be arranged on the top of arms will help us to get the better vision on the operating arms and to control the arms while the copter is away from controlling position.

[0009] Manual operating feature helps to collect the samples from the hazardous places without risk of losing lives, as this copter design helps to get better stability which helps flying in windy days many operations can be done through arms by high speed arriving to the executing place and also many applications in agriculture field.

[0010] All the electronics are small hence they can be fixed comfortably and also help reduce the size and weight of the copter.

[0011] The holding mechanism which is placed at the end of the arm chain is a simple mechanism to hold the object, it is controlled by the main body of the copter by a cable and a servo motor, a grip is given at the tip of the holder hence it is easy to hold an object.
