Misteri Planet Kegelapan di Tata Surya

Kalangan “orang dalam” di NASA, DoD (badan inteligensi militer), SETI maupun CIA sudah memprediksikan, kalau 2/3 dari penduduk planet bumi akan punah, ketika terjadi pergantian kutub, yang disebabkan kedatangan Planet X. Sisa populasi yang bertahan hidup, terancam bahaya kelaparan dan radiasi elemen, dalam jangka waktu 6 bulan setelah kejadian ini.



Semua operasi rahasia menyadari kenyataan ini, dan sudah menyiapkan diri mereka. Konon, Vatikan juga mengetahui hal tersebut. Namun sayangnya, masyarakat luas dibiarkan begitu saja tanpa informasi, dibiarkan terlena dengan kehidupan sehari-hari, tanpa punya kesempatan untuk menyiapkan diri menghadapi bencana ini.

Sejarah Pemikiran Manusia tentang Tuhan

Beberapa waktu yang lalu kita dapat melihat di dalam media massa bahwa banyak kelompok-kelompok religius yang sering kita sebut kelompok “Sesat”. Dimana hal itu merupakan suatu bentuk dari perkembangan pemikiran Tuhan yang semakin berkembang. Kata Tuhan merujuk kepada suatu zat abadi dan supranatural, biasanya dikatakan mengawasi dan memerintah manusia dan alam semesta atau jagat raya. Hal ini bisa juga digunakan untuk merujuk kepada beberapa konsep-konsep yang mirip dengan ini misalkan sebuah bentuk energi atau kesadaran yang merasuki seluruh alam semesta, di mana keberadaan-Nya membuat alam semesta ada; sumber segala yang ada; kebajikan yang terbaik dan tertinggi dalam semua makhluk hidup; atau apapun yang tak bisa dimengerti atau dijelaskan. Banyak tafsir daripada nama “Tuhan” ini yang bertentangan satu sama lain. Meskipun kepercayaan akan Tuhan ada dalam semua kebudayaan dan peradaban, tetapi definisinya lain-lain. 

Konsep Tauhid Kepada Allah Dalam Iman Agama Islam



(Surah Al-Ikhlash : Ayat 1-4)
“Katakanlah; Dialah Allah Tuhan Yang Maha Esa, Allah adalah Tuhan Yang bergantung kepada-Nya segala sesuatu. Dia tidak beranak dan tiada pula di peranakkan dan Dia tiada sesuatupun yang setara dengan-Nya”.

PENJELASAN : Inilah Konsep Tauhid yang sebenarnya, Allah swt berdiri dengan sendiri tanpa bergantung dengan sesuatu apa pun kerana segala sesuatu itu adalah bergantung pada Allah swt.

Setan Dari Golongan Manusia



Setan merupakan kata benda (nomina) umum untuk setiap entitas yang congkak, pembangkang dan menyesatkan. Baik dari golongan manusia atau dari golongan jin atau dari golongan mana pun. Dalam al-Qur'an setan tidak disebutkan sebagai entitas khusus, melainkan pada manusia jahat, penyebar fitnah, perusak juga disebut sebagai setan.

Karena itu, yang dimaksud dengan "syathin al-ins" adalah manusia yang tersesat dan menyimpang karena membangkang segala titah Ilahi dan juga berada pada tataran menyesatkan dan menyimpangkan orang lain.

"Sya-i-tha-n" derivatnya dari kata "sya-tha-na" yang bermakna menjauh. Lantaran menjauh dan menjaga jarak dari segala perbuatan baik dan menjauh dari rahmat Tuhan, maka ia dipanggil dengan nama ini.

Robotics Technology - Mobility




Industrial robots are rarely mobile. Work is generally brought to the robot. A few industrial robots are mounted on tracks and are mobile within their work station. Service robots are virtually the only kind of robots that travel autonomously. Research on robot mobility is extensive. The goal of the research is usually to have the robot navigate in unstructured environments while encountering unforeseen obstacles. Some projects raise the technical barriers by insisting that the locomotion involve walking, either on two appendages, like humans, or on many, like insects. Most projects, however, use wheels or tractor mechanisms. Many kinds of effectors and actuators can be used to move a robot around. Some categories are:
·    legs (for walking/crawling/climbing/jumping/hopping)
·    wheels (for rolling)
·    arms (for swinging/crawling/climbing)
·    flippers (for swimming)

Robotics Technology - Artificial Intelligence





The term "artificial intelligence" is defined as systems that combine sophisticated hardware and software with elaborate databases and knowledge-based processing models to demonstrate characteristics of effective human decision making. The criteria for artificial systems include the following: 
1) functional: the system must be capable of performing the function for which it has been designed; 
2) able to manufacture: the system must be capable of being manufactured by existing manufacturing processes; 
3) designable: the design of the system must be imaginable by designers working in their cultural context; and 
4) marketable: the system must be perceived to serve some purpose well enough, when compared to competing approaches, to warrant its design and manufacture. 

Robotics Technology – Arms



The robot arm comes in all shapes and sizes and is the single most important part in robotic architecture. The arm is the part of the robot that positions the End Effector and Sensors to do their pre-programmed business. Many (but not all) resemble human arms, and have shoulders, elbows, wrists, even fingers. This gives the robot a lot of ways to position itself in its environment.


Many robots resemble human arms, and have shoulders, elbows, wrists, even fingers. This gives a robot lots of options for moving, and helps it do things in place of a human arm. In order to reach any possible point in space within its work envelope, a robot uses a total of 7 degrees of freedom. Each direction a joint can go gives an arm 1 degree. So, a simple robot arm with 3 degrees of freedom could move in 3 ways: up and down, left and right, forward and backward. Many robots of today are designed to move with these 7 degrees of freedom.

Robotics Technology - Controllers



The robot connects to a computer, which keeps the pieces of the arm working together. This computer is the controller. The controller functions as the "brain" of the robot. The controller can also network to other systems, so that the robot may work together with other machines, processes, or robots. 


Given that the robot arm movement is appropriate to its application, that the arm strength and rigidity meet the payload needs and that servo drives provide the necessary speed of response and resolution, a robot controller is required to manage the arm articulations, its End Effector, and the interface with the workplace.  The simplest type of control, still widely used, is "record-playback," or "lead-through".  An operator positions arm articulations to desired configurations. At each desired location the articulation encoder positions are recorded in memory.  Step by step, an entire work-cycle sequence is recorded.  Then in playback mode the sequence is observed and modified.

Robotics Technology - Actuators




Actuators, also known as drives,  are mechanisms for getting robots to move. Most actuators are powered by pneumatics (air pressure), hydraulics (fluid pressure), or motors (electric current). Most actuation uses electromagnetic motors and gears but there have been frequent uses of other forms of actuation including NiTinOL"muscle-wires" and inexpensive Radio Control servos. To get a motor under computer control, different motor types and actuator types are used. Some of the motor types are Synchronous, Stepper, AC servo, Brushless DC servo, and Brushed DC servo.  Radio Control servos for model airplanes, cars and other vehicles are light, rugged, cheap and fairly easy to interface. Some of the units can provide very high torque speed. A Radio Control servo can be controlled from a parallel port.  With one of the PC’s internal timers cranked up, it is possible to control eight servos from a common parallel port with nothing but a simple interrupt service routine and a cable. In fact, power can be pulled from the disk drive power connector and the PC can run all servos directly with no additional hardware. The only down side is that the PC wastes some processing power servicing the interrupt handler. 

Robotics Technology - Effectors



An effector is any device that affects the environment. Robots control their effectors, which are also known as end effectors. Effectors include legs, wheels, arms, fingers, wings and fins. Controllers cause the effectors to produce desired effects on the environment.  An actuator is the actual mechanism that enables the effector to execute an action. Actuators typically include electric motors, hydraulic or pneumatic cylinders, etc.  The terms effector and actuator are often used interchangeably to mean "whatever makes the robot take an action." This is not really proper use. Actuators and effectos are not the same thing. And we'll try to be more precise in the class.  Most simple actuators control a single degree of freedom, i.e., a single motion (e.g., up-down, left-right, in-out, etc.). A motor shaft controls one rotational degree of freedom, for example. A sliding part on a plotter controls one translational degree of freedom.  How many degrees of freedom (DOF) a robot has is going to be very important in determining how it can affect its world, and therefore how well, if at all, it can accomplish its task. Just as we said many times before that sensors must be matched to the robot's task, similarly, effectors must be well matched to the robot's task also.
