2016-07-05 21:36:51 -0500 | asked a question | some questions about teb_local_planner_tutorials Thanks @croesmann provide repository of teb_local_planner_tutorials. When use it to simulate, i encountered some problems.
when I change the parameter controller_frequency to 20, the function of bool TebLocalPlannerROS::computeVelocityCommands(geometry_msgs::Twist& cmd_vel) is not every 50ms called once. In order to printf the time interval, in computeVelocityCommands, commented out codes from to and added some codes before In robot_carlike_in_stage.launch, when change controller_frequency to 20, the output in the terminal is shown below : the time interval of invoking computeVelocityCommands is not 50ms, but 0 and 99ms. When change controller_frequency to 10, it works well, the time interval of invoking computeVelocityCommands is 100ms, like below: I want to change controller_frequency to 20, and the time interval of invoking computeVelocityCommands must be 50ms, what should i do ? 2 . At teb_local_planner_params.yaml, change max_vel_x to 1.5. In computeVelocityCommands, commented out codes like 1; and add some codes before

2016-06-12 02:12:48 -0500 | asked a question | how can i simulate the Navigation use Indigo + RVIZ + Ackermann model? I have learned ROS(Indigo) for some time, and still a beginner. I just want to use ROS's Navigation stack to simulate some path planning algorithm. I have knew how to simulate the Navigation with Husky(differential drive robot) in RVIZ, but now, i need to simulate the Navigation with car-like model, i cannot find the solution method from Ackermann Group. |
2016-06-12 00:21:14 -0500 | commented question | how to simulate a ackermann model in gazebo I am a beginner in ROS(Indigo). Follow the tutorials, i simulate navigation with Husky(differential drive model) in ArbotiX, but now i need to simulate navigation with car-like model, could you please send your car-like model urdf to me? Thanks! |

2016-03-30 20:00:23 -0500 | answered a question | How can i simulate a global planner plugin in the ArbotiX Simulator? Know it.
Follow "ROS by Example":8.5.1 Testing amcl with Fake Localization.
Open fake_move_base_amcl.launch, under:
《node pkg="move_base" type="move_base" respawn="false" name="move_base"
output="screen" clear_params="true"》
add:
《param name="base_global_planner" value="carrot_planner/CarrotPlanner"/》 (use <> replace 《》) |
