Imagine a setting of the prehistoric time, a primitive man presenting a handmade toy to his spouse. The toy might have been a doll or an animal molded from mud or carved out of a piece of timber. It would have been easily one of the happiest moments of their life. Toys have always been a source of sharing happiness, communicating information and educating children. Toys such as birds, monkeys and small carts were excavated from the sites of Indus valley civilization. That was 3000 BC. Egyptian children played with winged dolls some thousands of years ago. Children used to play with wax dolls in ancient times in Greece. We have now toys that are made from wood, cloth, plastic and several other synthetic materials. Most often, these toys are mechanically driven or they are powered by batteries. These toys are mass produced in small scale cottage industries for local consumption and in large factories for sale in the global market. A toy provides entertainment. It improves mental and physical qualities of children. It stimulates creativity. It enhances reasoning. It teaches sharing. It improves the joyous ambience of a place. Where there are toys, there must be children around. We have entered into the 21st. Century with much din and bustle. Information technology spearheaded by the internet has taken the front seat. These days children like playing with 4G phones, tablets and computers. Children now need quality artifacts to match their intelligence quotient. We have remote controlled toys readily available in the market. The most amazing fact is that as soon as some innovations hit the market, its toy replicas also show up immediately. One can find remote control cars of almost all models. The toy market remains loyal to the antique and vintage value of a product also. We shall find cruise ship replicas of the ancient "Macro Polo" and the latest "Oasis of the Sea" side by side on the shelf. Ingenuity is at its best in designing and manufacturing remote control airborne toys particularly helicopters. One may find toy helicopters having almost all known types of rotor designs such as single, dual, coaxial, tandem, intermeshing, transverse etc. A teenager who despises studying Physics would learn intricate terms such as torque, tandem, lift, thrust, gravity, load etc., by the time he learns the intricacies of flying a remote control toy helicopter. The toy is the father of the invention. We have coined a more technical word for it. It is the prototype. Its dictionary meaning is, "A first or preliminary model of something, especially a machine, from which other forms are developed or copied."
