If you have tried the previous example, there is no feeling that every time the robot to move and input instructions in the terminal, this is too cumbersome, there is no way through the keyboard to control the movement of the robot? The answer room of course. I studied several other robot keyboard control code, or some harvest, finally transplanted to the SmartCa

In our previous blog, we learned about the overall framework of ROS positioning in navigation, and this article focuses on one of the most important move_base packages. As you can see in the overall framework diagram, Move_base provides the configuration, operation, and interface of Ros Navigation, which consists of two main parts: (1) Global Path Planning (Planner): Planning the overall path according

The use of ROS to develop a robot, in the use of the time to first connect the machine to the network and then roslaunch too much trouble, according to the product of the idea is to press the power button on OK. In addition, if there is a host computer connected to the state monitoring, in case the main program hangs, or modify the program to recompile operation, the host computer on this side of the node a

For mobile robots, keyboard control is often not enough to meet our needs, before watching a lot of movies inside are using a joystick to control the robot, is really handsome, just I have a joystick here, then to try to feel.

Machine vision in the computer age has become more and more popular, camera prices are cheaper, some integrated depth sensor hybrid sensor has gradually become popular in the field of research, such as Microsoft's launch of the Kinect, and its supporting software is very powerful, for the development of a great convenience.
