fly to build airplanes. In fact, people invent airplanes by aerodynamics, not by Bionics.So how can you understand natural language?General needs: Parsing statements, that is, through syntax. These grammatical rules are easier to describe with a computer. Gets the semantics. Semantics are more difficult to express in a computer than grammar. We can see a simple sentence.

ninth release of the toolbox, represents over fifteen years of development and a substantial level of maturity. this version captures a large number of changes and extensions generated over the last two years which support my new book "robotics, Vision control ". The latest release of the toolbox has been significantly extended to support mobile robots. for ground robots the Toolbox includes standard Path Planning Algorithms (Bug, Distance Transform, D *, PRM), kinodynamics planning (RRT), loc

operating systems. The biggest feature is the high performance of small power, the most suitable for running some long-running programs.

At present, the Cubieboard data is relatively raspberry less, after all, is the new veneer, but the cubieboard performance accounted for the absolute advantage.

Translator Note: This article: http://andrew.gibiansky.com/blog/physics/quadcopter-dynamics/ This paper introduces the dynamics and control model of four rotor, and simulates it in MATLAB, which is helpful to understand the working principle of the four rotor blades. The translator studied at the College of Aeronautical Science and Engineering, Beihang University, please specify the source. Only part of the code is given in the original text, a

In order to calculate the parameters in aircraft design, it is now necessary to translate a four rotor modeling related literature, which describes in detail the four rotor dynamics modeling and control system and simulation system, and gives some source code.Document Address: Http://andrew.gibiansky.com/blog/physics/quadcopter-dynamicsWe have found the translation of the first 7 pages of the document.Translation Address: Http://share.weiyun.com/9c186

 [excerpt from Baidu Encyclopedia] Monte Carlo method, also known as the statistical simulation method, is the the mid 1940s due to the development of science and technology and the invention of electronic computers, and was proposed by the probability of statistical theory as the guidance of a kind of very important numerical calculation method. means using random numbers (or more common pseudo-random numbers) to solve many computational problems. It corresponds to a deterministic algorithm.

, causing the arrow to deviate from the target. Qin Jun's three-Arn arrow removes the wing and should make shooting more accurate. The experts carefully analyzed these arrows and the researchers were incredible when the detection data was finally placed on the desktop. The detection results show that the three arcs of the arrow are almost identical, which is a streamlined arrow close to perfection. The outline of the arrow is almost the same as the shape of the bullet. The bullet shape is design

the projects that had been researched but did not have any results, or projects that were not successful, or the ones that were totally out of proportion to our upfront effort, and then I tried to classify them according to the reasons for failure and try to do a rigorous post-mortem. One of the failures was at Stanford when it was inspired by a V-shaped wild goose, and for some time we tried to get the aircraft to fly in this formation to understand the energy savings.

from the point of view of biology or neuroscience: Because of the present research aspects of human intelligence systems, especially visual systems, the human brain's information processing mechanism in this regard is a layered abstraction of hierarichical architecture (Serre et al., 2007). Although it sounds persuasive, it does not really explain why the multilayer structure is better, but just say that we have learned this way, so it sounds a little bit more vigilant not to be muddle through,
