2015-04-08 06:15:57 -0500 | answered a question | Vrep_ros_bridge installation problem I am able to solve the installation problem. It is not a problem with VREP_ROS_BRIDGE, is a problem with pluginlib libraries. Modifying /opr/ros/hydro/include/pluginlib/class_loader.h, including "#define TIXML_USE_STL" just before #include "tinyxml.h" solves the problem. |

2015-03-27 04:29:38 -0500 | asked a question | Vrep_ros_bridge installation problem Hello: I'm trying to install the vrep_ros_bridge package without success. I'm working under Ubuntu 12.04 and ROS Hydro distribution. I followed the installation tutorials, but when i execute catkin_make in my workspace this error appears: Any idea about this problem? My ROS Hydro packages are updated to last version. Thank you in advance! |
2015-03-26 09:38:58 -0500 | asked a question | Move_base: replanning issue Hello: I'm trying to configure move_base with my mobile robot platform and i am facing a serious issue. I am using ROS Hydro and navigation stack 1.11.15 I have configured the navigation package to follow the generated path as close as possible and when an unexpected obstacle appears in the path from outside the local window, the navfn and global_path is replanned and everything works OK. But if the obstacle appear near the robot (where the global path is already planned) it is not able to replan and approaches the obstacle until the robot stop. If I configure the global planner to replan at a certain ratio, it is able to replan avoiding the obstacle, but this is not the behaviour (periodic planning) we want in the real application, only replanning when the path is blocked. My configuration files are as following: Base local planner params: Local costmap params: Global costmap params: (more) |
