2016-12-06 05:45:09 -0500 | answered a question | Publishing to a topic via subscriber callback function I used this example fpr oublishing velocity from my joystick to my motor. But there is a delay. Maybe I can solve the problem by changing the publsih rate. How can I cahanged the publish rate at this example? |
2016-11-02 10:48:49 -0500 | asked a question | Kill/Stop node/launch I would like to stop the current launch by pressing a button on my joystick, but i can't find the right code for it, which command I can use to stop the node or better to stop the launch and the node? Thanks for help |

2016-11-02 07:02:05 -0500 | asked a question | Subsribe and publish conversion problem I'm trying to write an own Subscribe and Publisk node. I would like ti subscribe to the joystick and publish to my motors. For the publish i create with a launchfile to topics, I use the JointVelocityController for that, so they are from type std_msgs:.Float 64. And I think the type i get from the joy is Float32. So when ich start building the node i get this error: This is my Subscribe and Publish node: I think the problem is that i have different kind of types, but i don't now how i can converted them or what i can do. Thanks for your ideas |

2016-10-05 07:49:01 -0500 | asked a question | package to drive a robot I have 2 maxon motor with I have intizialed with the package epos hardware, now I have two topics, one for every motor. My robot should be drive with a Gamepaf now i need a program do send the velocity to the topic, so if i but the axe just to the left side just the left motor will get velocity and so on. Is there package with can do this? Thanks |
2016-09-29 07:50:17 -0500 | asked a question | controller_manager possible to have the same controller double Hey, i didn't unterstand much about transmission interface, I would like to start a launch double with different motors. But i get problems because when 1 start a second process the other dies and i get many errors. What I have to change so that i get a second joint_state_controller and a second velocity_controller. Maybe someone know a good documentation for controller_manager. This is the launch file i use: <launch> <node name="epos_hardware" pkg="epos_hardware" type="epos_hardware_node" args="actuator_left actuator_right" output="screen"> <rosparam command="load" file="$(find epos_hardware)/launch/epos_params.yaml"/> </node> I would be thankful, if someone can help me. |
2016-09-29 06:09:59 -0500 | asked a question | epos_hardware_node can't find parameters Hey,
i tryed to get the epos_hardware package ti work.
I have the right parameter in the yaml file and if i started the launch file directly with But when i wnat to start it with the epos_hardware_node like it is told at the wiki I get I think that the problem is that the node doesn't get the parameter and so i tryed to start first the launch and then the node i get his I'm new at ROS and didn't unterstand the problem, thanks for help |
