Encoder programming is based on STM32F407IG, and the pre basic knowledge is timer input capture.
Detailed explanation of principle
The types of encoders include incremental encoder, absolute encoder and hybrid absolute encoder. This experiment uses incremental encoder The schematic diagram of the basic encoder is shown in the figure below. Ro ...

teb_ local_ The planner is the base of the 2D navigation stack_ local_ Planner plug-in. An online optimized local trajectory planner is implemented to navigate and control mobile robot as a plug-in of ROS navigation package. The initial trajectory generated by the global planner is optimized during runtime to minimize the trajectory execution t ...

How does the Reader read the data of the Writer (underlying logic)
Last Article (upper logic) The process of reading data by the reader is described in, but there is no bottom-level Tansport. This is how to conduct inter process communication. Let's analyze it here.
In ReceiverManager::GetReceiver, call transport:: Transport:: instance() - &g ...

At present, the common methods of point cloud detection are
1. The point cloud is divided into voxels for detection. Typical models include VoxelNet, SECOND, etc; However, Dr. Shi, the author of this paper, proposed that this method will cause quantitative information loss.
2. Project the point cloud to the front view or aerial v ...
