2014-10-08 08:25:04 -0500 | commented answer | Global_planner package with A* planner question. @David Lu I've found out why A* gives a different path from Dijkstra. The issue is that you use the Manhattan distance has heuristic, if you use the Euclidean distance the paths will be almost identical. |

2014-09-30 04:42:28 -0500 | answered a question | Publishing and subscribing to an array and store it (in the right order) @Andromeda. BennyRe is right. If you check the documentation for the visualization_msgs::MarkerArray, it contains only one field, Marker[] markers. This field is a vector of markers to store it just declare a std::vector of that type. With that modification it should work. |

2014-09-29 03:56:38 -0500 | asked a question | People tracking with fisheye camera Hi all, I'm working with some fisheye cameras mounted on the ceiling. What I want to do it them is to track people, get their position in the ground plane and an estimate on their speed. I've never worked with this kind of cameras before, does anyone have any idea on how to tackle this issue? Thanks |

2014-07-29 09:37:29 -0500 | commented answer | Problems creating own robot in Gazebo with catkin_ws If you just spawn the model in Gazebo you'll have the model in the simulator but you'll not be able to control it with ros. If you want to use the model in ros you should use roslaunch to spawn it, so the topics from odometry and the sensors are published. |
2014-07-29 08:01:28 -0500 | answered a question | Problems creating own robot in Gazebo with catkin_ws Hi! You should download a urdf model, since it will be simpler to just spawn it in gazebo. If you want to create your own model you can follow the tutorial gazebo build model. It explains how to build a simple mobile robot. |

2014-07-28 12:30:34 -0500 | answered a question | set a path to move_base Hi! Assuming that you implemented a plugin of BaseGlobalPlanner to plan your paths, you can just publish the plan to topic and then you can see the results in rviz. You just need to do And then implement a method to fill a nav_msgs::Path msg and publish it. |

2014-07-21 14:28:54 -0500 | asked a question | Package "ompl" does not follow the version conventions Hi all! I'm trying do implement a base_global_planner plugin with RRT algorithm, for that I'm using the ompl package. The code compiles with no errors, and I followed the steps for registering the plugin but when I launch move_base I get the following error: The macro is set as: The xml file: CMakeLists The package.xml <package> <name>rrt_planner</name> <version>0.0.0</version> <description>The rrt_planner package</description> </package> I could not detect any error in the above code. So I think that the problem may be related with a warning I get when running catkin_make. The warning is the following: Is my assumption correct? If so how can I solve that warning? |
