Hi,<br><br>   Recently, I am learning <span style="background-color: rgb(255, 255, 51);">roslaunch</span> order, and I have some problem with it. First, I can drive the robot around manually in simulation using the keyboard when I type roslaunch p3robot teleop_keyboard.launch. But when I run roslaunch p3robot teleop_keyboard.launch in the real robot, the robot can&#39;t response. In the file of teleop_keyboard.launch, I set three private parameters. The src of my code and the .launch file are in the accessory. What is the matter? Why the keyboard can control the simulation robot but can&#39;t control the real robot with the same codes?<br>
Or there is some problem with my .launch file? Thank you in advance!<br>-- <br>Eileen<br>TJ University of Shang Hai<br><br>
