Navigation and positioning are important parts of robot research.
In a strange environment, a general robot needs to use a laser sensor (or a depth sensor to convert to a laser data), map modeling, and then navigate and locate it according to the established map. There are also many good packages in Ros that can be used directly.
In Ros, the three packages to be used for navigation are:
(1) Move_base: Ac
Last night, a buddy shouted, saying that his computer was infected with viruses and that anti-virus software could not be used or installed. I guess it was a robot dog.First, I used QQ to send a bot killer and drive killer. The bot killer report found av_killer_x. After the reboot, the virus was not cleared, and the drive killer did not report the virus.Remotely connected to the system, used the latest avterminator/
When talking about the concept of robot framework layering, you have to mention "keyword-driven ".
Keyword-driven: Different call keywords lead to different test results.
The method described in the selenium API in the previous section is actually a keyword. For example, "Open Browser" is a keyword. From the bottom layer, it is a method to realize through programming.
Def open_browser (URL, browser): # Find the corresponding browser driver through br

There is a M-row and N-column squares on the ground. A robot moves from the grid of coordinates 0,0, each time only to the left, right, upper and lower four directions, but cannot enter the coordinates of the row and column coordinates of the sum of the squares greater than K. For example, when K is 18 o'clock, the robot can enter the square (35,37) because 3+5+3+7 = 18. However, it cannot enter the grid (3
