agility robotics

June 13, the largest and most influential robot event--"China Robot Summit" was held in Yuyao, Ningbo. On the evening of 12th, Yuyao Liang Nong Town Party School Siminshan Branch held a party, on the stage of an AI pk "wonderful dialogue" staged, the Robot "Yaoyao" as the host, and the scene of female host mutual ridicule. And the Robot "Alice" and singers to sing together, the robot teams performing dance "Little Apple" also fully demonstrated the robot metal under the appearance of tenderness

Trajectory planning is a top-level problem in robotics, and its main goal is to plan the robot to move from A to B and avoid all obstacles.1. The object of the trajectory planThe trajectory planning object is map, after the robot obtains the map through the slam, it can select any two points in the maps for trajectory planning. For the time being, three-dimensional map is not considered, and the map mainly has the following types:　　As shown above, the

correspond to ALPHA*V1. The third column should correspond to the pixel coordinates of gama* "a". Alpha Beta Gama is a constant. "The coordinates after the projective change should be constant multiplied by the second coordinate".If Alpha Beta Gama can be solved, then we get the projective transformation matrix. Obviously the pixel coordinates of C point are brought into the equation, we have 3 equations, 4 unknowns (introduced a lamda). But Lamda does not affect, in addition to the past, we ju

range, because Sigma describes the scale, the location of the feature point + the scale = The local information of the feature point. On this basis, the gradient direction of all the pixels in the field is counted, and the hog feature is constructed by the direction statistic histogram as the eigenvector. It is important to align the main direction of the image and the x-axis direction before the direction of the statistic. As follows:　　The yellow something like a clock is a feature point +scal

information, and the columns represent constraintsEach row is the error of a point in that position, and each column represents the partial derivative of the F pair of X components.　　Q x c are variables, q is the rotation of four elements, X is three-dimensional point space coordinates, and c is the coordinates of the camera's center of light in the world coordinate system. J can be divided into three parts, the first 4 columns represent the derivation of rotation, the middle three column repre

configuration Space.The essence of this algorithm is the Monte Carlo algorithm. This makes it easy to parallelize on the GPU. The biggest difficulty is still in the non-free Area inspection section ...　　The green point is a random sampling point.2. RRT algorithm for generating one-time path in spaceMost of the time, we don't need to generate an entire map that can be reused, and we need to find a moving path in space. For example, an unmanned car from a to B, we only need to generate a single p

September 23, the North Branch day painting Company in Zhongguancun Software Park held a product launch, launched two new LiDAR products, of which r-fans-32 is the history of the smallest 32-line LiDAR, C-rans is currently the highest number of local field laser radar. R-fans is a navigation-based LiDAR developed by North Dakota for autonomous driving, intelligent robotics, unmanned mapping and SLAM applications. R-fans-16 and r-fans-32 have the char

the success. delay Start Long connection The long connection above the pattern, there is a small flaw, I must be connected to the server when switching long connections, but my software may not be read immediately, it may be a long time before starting to read data, so this component also supports the manual setting of long connections, until the first time to read the data to start the connection server, The subsequent operation is consistent with the above. The whole logic is like this.

displayed, such as the following syntax: [Regular expression] 1. However, the learning curve of regular expression is very high. If you want to use it to parse HTML and customize it, there is really no affinity for general developers. Another characteristic of HTML is its hierarchy. Therefore, when interpreting it, the browser uses the document tree method and uses recursion) but regular expression does not support hierarchical analysis. The most useful tool for hierarchical analysis is XML pa

Project Team, he will make a lot of criticism on the Agile Project. This is not good, and it is not standard. After all, it takes a little time for me to see through the management methods of a project. Therefore, for projects that implement agile management, remember to placate everyone from a traditional project. Such people may think they have a complete management system, however, these systems tend to be slow with agility. It is essential to app

From: infoq Qiao Liang Is methodology and architecture mutually exclusive? Some people think that software development practices and architecture are not repeated. This may be true in other environments, but it is not true in this topic. On the one hand, agile methods (such as XP) directly focus on design, rather than specifically agreeing to the idea of doing a lot of design (bduf) in advance. On the other hand, most SOA teams primarily focus on functional teams that build a series of servi

From declarations to principles, to practices, agile development has also been organized to begin agile certification activities. Individuals and interactions over processes and toolsWorking software over comprehensive documentationCustomer collaboration over contract negotiationResponding to change over following a plan A few days ago, I heard an introduction to the agile basic class. I have added the process to the agile development time. I think that fast can be linked with the proc

Some days ago, I attended the 10th China system and software process improvement Annual Meeting, one of which was the cmme and agile dialogue (it is said that last year was a debate, the fire smell is too strong due to the intention to allow everyone to express their own ideas in an extreme way. So this year, we changed to dialog ). CMMS emerged in a way that embraces agility. Several agile representatives seem to be purely technical and have a weak l

problems in practice. I firmly believe that the people on the market in China who advocate agility and perform training everywhere have their own practical experience? Agility is a real thing. Every team has a different way of playing, because she has no theoretical foundation and no special methodology. This is a collection of previous experiences. The experience of the predecessors will certainly not be

Hello long time no see Haha, today for everyone to share a parsing HTML class library HTML Agility Pack. This is useful for trying to get some content inside a webpage. Take a list of my csdn blogs today for example.Open page Use Firebug to find the content area of the article ListAs shown in the picture above we have found the location of the desired content in HTMLSo the first step is to get the HTML and then use the HTML

I previously posted an article about html-to-xml Conversion, which attracted the attention of many netizens. The implementation method is to use htmlparser to break down html content, and then generate xml strings one by one according to the dom structure. After failing to fully implement the solution, I thought the solution could solve the problem. However, after actual use, the efficiency is indeed very low, and the conversion of some special html attributes is not supported, the results are n
