The robot can be used for human operations in hostile environments to perform (in space, in the deep sea or on the battlefield). Or numbing for very precise actions to perform (in the industrial, household or medicine).
In rehabilitation applications, the robot hand to ordinary everyday actions to perform. The robot compensates the limitation of the user. In addition there are three approaches:

• A robot that runs with the three robotic laws, as a sort of assistant to certain tasks. The technical design philosophy of such a robot assistant is equal to what is described above. The user gives commands to the assistant which he must understand and implement. This requires a “high” semantic communication between the user and the assistant. Moreover, the robot must have a good repeatable and predictable features. That is difficult in an unstructured environment.

• A manipulator that no robot can be named because together with the user as an acting unit he should be considered. Task, job, planning and collision avoidance by the useing real-time. The eyes of the user and the interpretation of what he sees replace optical sensors and interpretation software. Interpretation of an image requires recognition of the environment and objects therein. This requires either a “technical software moderate” or a “human” virtual world model. Man today it is far superior. This approach gives the user free rein to his creativity as it functions in real-time spot can think and execute. Drawback is the slowness of control because the level of movement takes place and not “abstract task” level (as in the robot: make dinner). All movements should be sent with weak finger or eye movement.

• The combination of robot and manipulator: A manipulator can remember and redo the tasks. Advantage is the acceleration of the movement of already learned tasks. The disadvantage is the extensive language between the user and the robot at different semantic levels (complex and simple movement task). Also the the robot must have higher mechanical precision because he lacks the feedback from the user. And also potential conflicts between the virtual world of the user and the robot.

The robotics is the science and technology of robots. It deals with the design, manufacture and application of robots. Robotics combines various disciplines such as: the mechanics, the electronics, the computer, the artificial intelligence and control engineering. Other important areas in robotics are the algebra, the programmable logic and state machines.

The term robot was popularized with the success of the play RUR (Rossum’s Universal Robots), written by Karel Capek in 1920. In the English translation of this work, the Czech word robota, meaning forced labor, was translated into English as a robot.

History of Robotics

The history of robotics has been linked to the construction of “artifacts” that tried to embody the human desire to create beings in his likeness and download it work. The Spanish engineer Leonardo Torres Quevedo (GAP) (who built the first remote control for cars by telegraphy without wire, the chess machine, the first air shuttle and many other mills) coined the term “automatic” in relation to the theory of automating tasks traditionally associated with humans.

Karel Capek, a writer Czech, coined in 1921. the term “Robot” in his play “Rossum’s Universal Robots / RUR” from the word Czech robota , which means servitude or forced labor. Robotics is the term coined by Isaac Asimov, defining the science of robots. Asimov also created the Three Laws of Robotics . In science fiction, man has imagined the robots visiting new worlds, gaining power, or simply relieving the house work.

Classification of robots:

According to the chronology this is the most common classification:
Generation 1.
Manipulators. They are multifunctional systems with a simple mechanical control system, either manual or fixed sequence of variable sequence.
Generation 2.
Robots are learning. Repeat a sequence of movements that has been previously executed by a human operator. The way to do this is through a mechanical device. The operator performs the required movements while the robot remains and stores.
Generation 3.
Sensorised control robots. The controller is a computer running a program, orders and sends them to the handler to perform the necessary movements.
Generation 4.
Intelligent robots. Similar to above but also have sensors that send information to the control computer on the status of the process. This allows them intelligent decision-making and control of real time processing.

While bio-fuel might produce an alternative to fossil fuels, the rising cost for resources used in bio-fuels creates a new dilemma. Many poorer countries spend much of their income feeding their population and rising food costs create new shortages in the wake of more expensive foodstuffs. On the other hand, other poor countries with strong agricultural bases benefit by a lack of competition in the international market and higher profits for their crops. Read the rest of this entry »

During the 20th century, the automobile became our chief mode of transportation. Now, in the 21st century, automobiles are sophisticated and constantly evolving machines.

Automotive engineering is the broad field of study that makes this technology and innovation possible. The core components of automotive engineering include design and performance, drivetrain engineering, engine combustion, engine tribology, mechanical engineering and vehicle dynamics.

Aerodynamics is the study of the interaction between air and moving objects. It is vital to understanding how planes and rockets fly but is also used to understand everything from how kites can stay aloft to how a baseball pitch can curve. Aerodynamics is also studied in relation to objects moving along the ground such as cars or runners. Aerodynamics can also be used to study wind loads in the design of structures and to study the internal passage of air through ventilation systems and gas piping. Read the rest of this entry »
