On what principle does a robot work?

Answer 1

I would describe a robot as a computer program that can actually perform some physical action. I don't know if they have principles though.

Answer 2

the main principle is"Artificial intelligence (AI) is arguably the most exciting field in robotics. It's certainly the most controversial: Everybody agrees that a robot can work in an assembly line, but there's no consensus on whether a robot can ever be intelligent. Like the term 'robot' itself, artificial intelligence is hard to define. Ultimate AI would be a recreation of the human thought process -- a man-made machine with our intellectual abilities. This would include the ability to learn just about anything, the ability to reason, the ability to use language and the ability to formulate original ideas. Roboticists are nowhere near achieving this level of artificial intelligence, but they have had made a lot of progress with more limited AI. Today's AI machines can replicate some specific elements of intellectual ability."

Answer 3

A robot is an electro-mechanical device that can perform autonomous or preprogrammed tasks. A robot may act under the direct control of a human (eg. the robotic arm of the space shuttle) or autonomously under the control of a programmed computer. Robots may be used to perform tasks that are too dangerous or difficult for humans to implement directly (e.g. nuclear waste clean up) or may be used to automate repetitive tasks that can be performed with more precision by a robot than by the employment of a human (e.g. automobile production.)

Robots may be controlled directly by a human, such as remotely-controlled bomb-disposal robots, robotic arms, or shuttles, or may act according to their own decision making ability, provided by artificial intelligence. However, the majority of robots fall in-between these extremes, being controlled by pre-programmed computers. Such robots may include feedback loops such that they can interact with their environment, but do not display actual intelligence.

The development of a robot with a natural human or animal gait is incredibly difficult and requires a large amount of computational power [8]. Now that background technologies of behavior, navigation and path planning have been solved using basic wheeled robots, roboticists are moving on to develop walking robots (eg. SIGMO, QRIO, ASIMO & Hubo). One approach to walk control is Passive dynamics, where the robot's geometry is such that it will almost walk without active control.

Initial work has focused on multi-legged robots (eg. Aibo), such as hexapods [9], as they are statically stable and so are easier to work with, whereas a bipedal robot must be able to balance. The balancing problem is taken to an extreme by the Robotic unicycle. A problem with the development of robots with natural gaits is that human and animal bodies utilize a very large number of muscles in movement and replicating all of those mechanically is very difficult and expensive. This field of robot research has become known as Biomorphic robotics.

Answer 4

A "robot" is NOT a single unit, but rather a collection of systems that when designed to work together can result in their collective producing a desirable outcome.

Answer 5

principle? just hardware (the circuits, etc.) then you program the logic (usually using principles from Artificial Intelligence (AI) and/or neural networks for starters)... however, it's limited for now mostly because of processing power/capabilites (hardware still can't compute logic fast enough last time we were taught in college hehe)

Answer 6

It does not have any special principal . It works on the electronic circuits from which it is built. Programming is another factor on which it works

Answer 7

Input the information once and it will produce the output at a faster rate. It will always need to be told what to do.

Answer 8

Engineering to build the body and programming, possibly AI to operate it.

Answer 9

''Robot'' means ''work'' so your question makes no sense
