Dynamic Window Approach (DWA) is an important local trajectory planning algorithm, and the DWA algorithm is used in Ros to obtain good local path planning results. Here are some very good information.Resources:[1]. dynamic window method for local obstacle avoidance of robots (approach) (* * * *)[2]. Autonomous Robot Navigation[3].

The wireless network card on the book was so miserable that I went on strike more than a month ago. There was something wrong with the network card.
Yesterday in the Pearl River Road hand bought a D-link DWA-131 wireless network card to take over, found in Ubuntu driver compilation is quite difficult
After Google finally solves various errors encountered during compilation, record them

Well, I admit that it was my fault that I was careless on the weekend, but I didn't stop thinking completely. When I was in the drama, or the heart of the Nginx, the understanding of nginx in the process of the pot play further deepened.Nevertheless, there is no way to write a summary, after all, it is too much food.It is now possible to configure it as a static resource server, which should be more than enough for my project resources. Next is how to let Nginx and MySQL communication, based on

A simple question is a "water question". You only need to consider various situations. In special cases, the values are 5, and the values are 0, 1235555, and 555123. In my opinion, this is the case. You only need to consider it as complete. Question:
It can be used as an entry-level question for STL. I forgot to consider that the last character string should not end with 5, so there is always one less data ..

the popularity of Apple devices, 5G wireless network cards are installed in the latest MBP/MBA/IPAD, so 5G users are also quite impressive. At the same time, in newer Windows laptops, dual-band wireless network adapters are also increasingly used. This test mainly verifies the specific performance of wireless transmission under 2G and 5g. The output conclusions serve as a reference for the future use of wireless devices. In this test, four devices are used:

Restoration test: Add a new virtual disk and use g4l to restore the centos system from the sub-disk to the sub-disk.The process is omitted, just like above.
Note:If the target disk capacity is the master disk, the default capacity of the target disk is the same as that of the master disk.Solution:-------------------------------5.1 check the partition status of the master disk a
Speaking of Greenplum, SUN was the first product that was introduced when SUN pushed their data warehouse product DWA. He was not very familiar with this database product stacked by PgSQL, at that time, the focus was still on DWA's hardware. Of course, DWA still had some features.
Later, we found that general PC + SAS disks have very good throughput capabilities, not inferior to some expensive storage devic
http://answers.ros.org/question/10718/dwa_planner-vs-base_local_planner/
The dwa_local_planner supports velocity constraints specified in X, Y, and Theta while the Base_local_planner only supports constraints specified in X and theta. There is some-y velocities, but the users are limited to a pre-specified list of valid y velocity commands. This makes the Dwa_local_planner a better choice for robots that is holonomic or pseudo-holonomic because it allows for B Etter sampling of the velocity
