Teknologi Robot Masa Depan

Sejauh yang saya ketahui robot adalah sebuah peralatan canggih yang dibekali dengan sistem kecerdasan buatan yang dibuat untuk bekerja secara otomatis ataupun semi-otomatis dalam rangka membantu pekerjaan manusia. Dalam perkembangannya kegunaan secara garis besar robot bisa dibagi menjadi dua yaitu untuk keperluan sipil dan untuk kepentingan militer.
 
ilustrasi
Robot untuk kepentingan sipil bisa kita kenali misalnya seperti robot-robot industri, robot pemandu dan robot mainan. Jenis robot semacam ini banyak dikembangkan di negara Jepang seperti misalnya yang paling terkenal adalah Asimo sebuah robot pemandu museum. Robot dengan dua tangan dan dua kaki layaknya manusia ini dibekali dengan banyak sensor agar mampu melakukan berbagai gerakan sebagai respon dari lingkungan di sekitarnya. Hanya saja masih ada beberapa kekurangan berupa sedikit “kebingungan” dalam mengenali objek atau gerakan tertentu yang ada di sekitarnya sehingga perlu dikembangkan lagi.

Sedangkan robot untuk kepentingan militer adalah robot yang dipakai untuk kepentingan perang misalnya untuk memata-matai lokasi musuh atau untuk melakukan serangan terhadap objek yang telah diidentifikasi sebagai musuh. Robot semacam ini biasanya dalam bentuk pesawat tanpa awak yang dikembangkan oleh beberapa negara kampiun teknologi seperti Amerika serikat. Bahkan robot semacam ini telah dimanfaatkan pada sejumlah operasi militer seperti di Afganistan dan Irak. Hanya saja dalam penggunaannya masih belum benar-benar otomatis sehingga masih diperlukan otorisasi dalam melakukan sebuah serangan yang telah terdeteksi. Ini karena teknologi masih belum bisa dipercaya sepenuhnya apalagi bila bersangkutan dengan nyawa manusia bahkan puluhan atau ratusan nyawa manusia.

Piper J-3 Cub RC Aircraft


piper-j3-cup-rc-airplanes
Piper J-3 Cub Aircraft is a type of light aircraft with an engine propeller and the upper wing configuration. Piper J-3 Cub Aircraft manufactured between 1937 and 1948 by Piper Aircraft is intended for training aircraft, which has two seats (fore and aft seating). Between the years 1938 until 1947, these aircraft have been sold over 19.073 units. A very fantastic sales figures. Even in times of wars, orders rose sharply on these airplanes, so the plant was able to make an average of one airplane in 20 minutes.

Although at this age Piper J-3 Cub aircraft was very old, but these airplanes was not a few that are still viable to operate. This is probably due to the uniqueness and history of the war so that the owners of these airplanes take good care of this.

For those of you who are in the stages of learning to fly rc airplane, then I think Piper J3 Cub RC Aircraft is very suitable for you. Type of engine that use propeller make these rc airplanes flying at low speed so it is more easily controlled than those using jet engines. In addition, the stability of this type of Piper J-3 RC Aircraft is high enough. It is caused by the placement of the wing at the top position (upper wing). Upper wing configuration like this also allows us to use a shorter runway distance both during take off and during landing.

And those who are already proficient, Piper J-3 Cub RC Aircraft capable of landing with the engine turned off. Wing configuration above will produce a larger lift, so it can land by gliding safely. However, for beginners, I still recommend to first learn basic techniques using a simulator through your computer. May be useful.

Knowing Giant RC Airplanes


giant-rc-airplanes
There are so many types of rc airplanes as well as there are so many types of the real airplanes. Of the many types of rc airplanes available, there are some rc airplanes with great scales. They are almost called as a giant rc airplanes. Of course that giant rc airplanes are not designed for beginners, but they are designed for advanced users. It is caused of great scale/size that have a larger risk when they fall to the ground.
 
Giant rc airplanes are very expensive. Some of the  giant rc airplanes cost upwards of $ 9,500 included engines and electronics. Because of the size, high torque servos are required on every control surface like elevators, ailerons, ruders and flaps, in order to withstand the high loads caused by the extra weight  and size of these giant rc airplanes.

Giant rc airplanes almost use gasoline engines that is believed as an fuel efficient engines that is opposed to the nitro engine used by most smal size rc airplanes. This is quite reasonable because they require larger and stronger engines, more servos. These requirement make giant rc airplanes more expensive than the average rc airplanes. Giant scale rc airplanes is also potentially to get great danger in their operations. So, you must be previous competent in using beginner rc airplanes before using these giant rc airplanes.

Fact About Gas RC Airplanes


(ilustration)
Gas RC Airplanes in general are rc airplanes powered by gasoline. The term of gas rc airplanes is often used to name all types of IC (internal combustion) powered planes. Flying gas rc airplanes is not as simple as flying electric rc airplanes. Gas rc airplanes have more complicated controls than electric one. Great power produced by these planes produce high speed in flight so that i dont recommend gas rc airplanes to be used for beginners.

Gas rc airplanes are a fun for an experienced pilot. They can be faster in flight. If you are an expert, you can try one of the airplanes powered by jet engines. These gas rc airplanes type are famous for their aerobatic and their improved aerodynamics make them have high sensitivity in controling. Therefore, this is an exciting challenge for you.

Even so, for those of you who are beginners need not worry, because now there has been specially designed gas rc airplanes for beginners. Some examples are several types of aircraft cessna designed to position the wings on top. Wings position which is above provides benefits to beginners, which is easily controlled, easily landing and take off.

In addition to choosing the wings that are placed on top, for a beginners, you can also choose the type of aircraft that has a wide wing design. Large wing design makes your plane more stable, faster, and it can take off/landing with a low speed, so it is suitable for those of you who are still learning.

Airplanes RC : Do You Know


(rc airplane)
The presence of Airplanes RC can not be removed from the invention of airplanes and radio control technology. Aircraft technology beginning of a series of scientific tests to fly by Ibnu Firnas (810-887), from Andalusia/Spanish. While the radio control technology has been used since 1893, when Nikola Tesla created a boat that is controlled by radio waves. At least, these two technologies is the underlying idea of ​​the airplanes rc. So that, in 1917 the first airplane rc has been successfully created.

Airplanes rc are airplane models that have the ability to fly like a real plane, with controlled by using radio control. Airplanes rc can take off, fly with a variety of flight maneuvers, and go to landing. Even airplanes rc can also be used to carry out air monitoring missions by placing a small camera on the airplanes.

Today, along with the development in airplane industry, it appears so many models of airplanes rc. In general, based on the pusher power, airplanes rc is divided into two types, namely propeller rc airplane and jet rc airplane. For a beginner, then I suggest to use a propeller rc airplanes or helicopters, because they have low speed, so it will be easier to control. More specifically, if you choose a propeller rc airplane, it will be safer if you choose the type of airplanes rc which the propeller is in the back position because it would be safer when your airplanes often get crash.

One more thing, now you can use airplanes rc simulator that you can play through your computer. This could be an alternative if you have enough money to buy the software. With this simulator, you will not to fear to get repeatedly crashes when learning to fly airplanes rc.
