2018-09-19 14:26:25 -0500 | marked best answer | Navigation stack Hi everyone, I am trying the ROS navigation stack for the first time, and I am trying to navigate my mobile robot to a given position. Right now was trying to this using an empty map and a robot that does not have any sensors. is that possible? I've been able to move it by publishing to the cmd_vel topic, so I know that everything from the urdf to the launch files I'm using are currently okay. I was wondering I could I quickly generate an empty map, since it seems to me that's exactly what I'm missing. Any thoughts? Thanks, Hugo |

2016-08-02 07:53:33 -0500 | commented answer | How to generate different random cmd_vel messages? Thank you very much mig. the stackoverflow discussion was where I found the answer to my problem. The reason why I had srand commented was because when it wasn't it still didn't work. I had to both have it outside the while loop and initialize it like suggested in the discussion. Thank you! |

Thank you very much for your comment but everything seems to be fine, from the rostopic list i get both /robot1/cmd_vel and /robot2/cmd_vel. and from rostopic info i get both publishers /robot1/pubvel and /robot2/pubvel. Naturally, rqt_graph also shows this. I still get the same cmd_vel for each... |

2016-08-01 13:34:16 -0500 | asked a question | How to generate different random cmd_vel messages? Hello everyone, I'm trying to have two (or several) robots receiving a random cmd_vel message. I was expecting that each robot would present a different velocity (I'm using Gazebo) but instead what I get is that every robot has the same velocity (however random, it is still the same for each one) publisher pubvel is below as well as my launch file where I launch both the robot model and the publisher within the same namespace. One namespace for each robot. <launch> <group ns="robot1"> </group> <group ns="robot2"> <node pkg="random_vel" type="pubvel" name="pubvel" output="screen"/> </group> </launch> Thank you very much in advance, Hugo |
