Background of the invention:
[0001] Many experiments based on the generating free energy using magnet’s repulsive force, most of the applications are in bearings and machinery later it is noticed that vehicles that consume less energy frequently are considered to apply magnetic repulsive technique to increase the output from the work done.

[0002] All these experiments are carried out to generate the electricity or to extract the high amount of output energy from the existing motor. Since remote control planes or micro unmanned vehicles works with the electric brushless motor the requirement is very specific so, this is the best place to apply the magnetic repulsive technique.

[0003] In this product we are trying to use the rotational energy generated from the magnet repulsion forces to propel the plane and also to power the other requirements in it. We are building the mechanism which directly converts the repulsive forces into rotational force to power the propeller. Plane is designed to very light weight so, as to decrease the power required.
Summary of the invention:
[0004] The present disclosure proposes a copter with foldable wings robot. The following presents a simplified summary in order to provide a basic understanding of some aspects of the claimed subject matter. This summary is not an extensive overview. It is not intended to identify key/critical elements or to delineate the scope of the claimed subject matter. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

[0005] In order to overcome the above deficiencies of the prior art, the present disclosure is to solve the problem by providing a copter with foldable wings is a combination of copter and foldable wings. The additional feature like producing lift through wings is a very useful to reduce the consumption of power to while flying.

[0006] Copter with foldable wings is a combination of copter and foldable wings. The additional feature like producing lift through wings is a very useful to reduce the consumption of power to while flying; the wings placed on both sides of the copter can be folded thus the copter will be small to handle and also helps while vertical take-off; the propellers placed diagonally on four sides are ducted and are also can be tilted as our wish; as the copter is now capable of gliding and hovering we can perform vertical take-off and also short take-off, in the same way vertical lading and short landing can be performed; also a set of landing gears are attached to the copter with foldable wing helps for any type of landing and take-off.

[0007] The copter with foldable wings is given a smooth aerodynamic surface right from the leading edge till the end of the copter to reduce drag when the copter turned into a plane with fully stretched wings and all the components including the wings are inside this smooth surface through this the component will also be safe while flying, also a camera is placed in front of the copter to get the front view.

[0008] The body of the copter has two layers or compartments which are separated each one for power system and wing system, the below part of the copter helps placing the circuit and other components require for quad copter other than the wings arrangement, the lower chamber helps arrange the wings and all the components required to run the mechanism.

[0009] The copter with foldable wings will be very useful in many applications like surveillance, chasing etc. The design of copter with foldable wings is very efficient with all the operations it is performing and the copter is very compact which makes carrying easy.

[0010] Most of the operations in the copter is done with gears attached to the motor and they are differ in size with reference to the operations done with it, we use this gear system in performing the folding operations and also to tilt the ducted fans placed around the copter.

[0011] The copter when reaches the required height the motors which are ducted will be started tilting in the same time the wings on the both sides will be opened and starts facing its tasks, this folding arrangement direction is fixed by considering the direction of force acting, the tilting of the ducted arrangement is done by using servo motors.

[0012] High definition cameras that can be arranged in front of copter will help us to get the better vision on the operating wings and to control the foldable wings while the copter is away from controlling position.

[0013] As the electronics used in folding mechanism on wins as well as tilting motor are very small enough to consume very less energy so no need of extra set of power supply for these mechanisms.

[0014] The whole system of foldable wings is placed at the centre of gravity of the copter which helps in increase the performance of the drone, and the folding and closing of the wing doesn’t affect the centre of gravity of the plane copter.

[0015] Further, objects and advantages of the present invention will be apparent from a study of the following portion of the specification, the claims, and the attached drawings.
