preface Recently, when learning autopilot system, I met the concept of co operation. The process and thread have been lost, and there is another collaborative process. I believe many friends have the same idea as the author. After reading a lot of materials, they decided to write a summary to summarize the connections and differences bet ...

At present, we intend to use python to write an Astar global path algorithm, which is generally divided into three parts: receiving map data, designing path (of course), and publishing path. 1, Build function package Create a new function package and import the dependency: gmapping map_server amcl move_base roscpp rospy std_msgs Create a n ...

Phase I summary Tip: it mainly involves combing the ideas of each class and summarizing the usage of python preface In the process of learning, I encountered many functions and didn't know how to use them. I checked the data and understood it at that time, but later I forgot it. So I recorded what I learned from scratch for reference ...

1, Principle of topic communication The implementation model of topic communication is complex, as shown in the figure below. The model involves three roles: ROS Master (Manager) Talker (publisher) Listener (subscriber) The ROS Master is responsible for keeping the registered information of Talker and Listener, matching Talker and Listener wi ...

Welcome to use the Python programming tutorial to learn the third parts of Carla automatic driving / self driving car. In this tutorial, we will use our knowledge of the Carla API and try to turn this problem into a reinforcement learning problem. After OpenAI took the lead in developing the open source of reinforcement learning environment an ...

In fact, most of the progress in image classification can be attributed to the improvement of training process, such as the increase of data and the change of optimization methods. However, most improvements are not described in detail. Therefore, the authors test and implement these improved methods in this paper, and evaluate the impact of th ...
