(1) What is SLAM?    in short, slam is to locate and pose the robot where GPS cannot be used, build incremental maps, and realize the autonomous positioning and navigation of the robot. Like a blind man, he explores the environment with his own hands in the unknown environment, and constantly corrects the map built by his heart to th ...

Training data generation Detailed step reference Modification of configuration file This article takes the human hand detection as an example (there is only one label: hand) Add or modify data / hand Names file, which records labels, one label per line (Note: labels corresponding to training data)Add or modify CFG / hand Data file, the cont ...

ROS learning notes (II) file system Opening: file system structure of ROS. To learn to build a ROS project, we must first understand a ROS project, understand their organizational structure, be fundamentally familiar with the organizational form of ROS project, and understand the functions and functions of various documents, so as to carry out ...

1. Particles stay SLAM GMapping (4) SLAM processor Each particle updated by particle filter independently records a possible robot trajectory and environment map In order to improve efficiency, GMapping designs a data structure of trajectory tree The trajectory of the robot can be obtained by tracing from the leaf node to the root node ...

How to use generalized inverse kinematics to plan the joint space trajectory of a manipulator? Combining multiple constraints, a trajectory is generated to guide the gripper to the cup placed on the table. These constraints ensure that the gripper approaches the cup in a straight line and that the gripper is kept at a safe distance from the ta ...

We are working on the implementation of Google cartographer algorithm these days. Two days ago, we realized the implementation of indoor mapping of Google cartographer. However, the map is based on the museum data provided by Google. We just download the data package and reproduce it, not the map in our own laboratory or around. We can see the ...
