| 2013-07-09 08:27:02 -0500 | asked a question | using and communicating between multiple quadrotors (usign hector_quadrotor) Hi all, I am doing a project which simulates multiple UAVs going around a specified area (the project I am working on is a flooded area for search and rescue) sending an image stream back to the user. I am currently familiarizing myself with using the hector_quadrotor package (which is quite a challenge given that I have never used neither ros nor gazebo before). Now I am trying to find out how to spawn multiple UAVs (ideally from the same terminal) and how to communicate between the robots for collision avoidance whilst going around the entire area. Could someone kindly give me a few pointers on how this can be achieved efficiently using ROS? Thanks a lot in advance, JP |

| 2013-07-04 23:07:33 -0500 | commented answer | UAV simulation using ROS/Gazebo and Matlab Wow thanks for that! I have decided to write the code directly in C++ instead of using Matlab since it seems to be the more straightforward option but at the moment I'm trying to get the whole thing to work with Gazebo 1.8 since the version used in the simulator_gazebo package seems to be outdated! |

The problem is that the camera feed is not appearing in rviz...could it be related to this error? Error [SDF.cc:760] Missing element description for [CxPrime] That is now being followed by various lines which state that the Camera plugin is missing <CxPrime defaults to 0> |

| 2013-06-30 06:04:03 -0500 | answered a question | Building hector_quadrotor failed Hi, I have a similar error. As far as I know I have installed all the dependencies (to install the dependencies all you need to do is rosdep install [package] right? I'm a bit new to ROS). The error i'm getting is this: {------------------------------------------------------------------------------- mkdir: cannot create directory `build': Permission denied -------------------------------------------------------------------------------} [ rosmake ] Output from build of package hector_uav_msgs written to:
[ rosmake ] /home/jpcallus/.ros/rosmake/rosmake_output-20130630-085101/hector_uav_msgs/build_output.log
[rosmake-3] Finished <<< hector_uav_msgs [FAIL] [ 0.06 seconds ] Can someone kindly help me out? I cannot find out what's wrong :/ As with the guy above when I try running the same roslaunch command i'm getting the following error: ERROR: cannot launch node of type [message_to_tf/message_to_tf]: can't locate node [message_to_tf] in package [message_to_tf] Cheers |
| 2013-06-27 23:18:17 -0500 | asked a question | UAV simulation using ROS/Gazebo and Matlab Hi guys, I'm pretty new to the whole Gazebo/ROS software and I need to do a project using them and came across a few queries, could you help? First of all, what I want to do is to control a UAV in simulation via Matlab. Could someone kindly explain how this could be done and from where should I start? From what I understood so far, I would need to simulate the robot in ROS and communicate with Matlab via ROS while using Gazebo as the simulation environment, is that so? If so how can I do this? Practically I would like to give the robot a target location from Matlab and let the robot go there. Secondly from what I can understand the best quadrotor to use is the hector_quadrotor (can't publish the link since I'm new to the forum :/). I've been trying to get this to work but seem to be running across a few difficulties. I have tried installing the hector_quadrotor package by first cloning the git link then using rosdep to install and roslaunch (again I was following the link to install packages used in asctec_drivers but I can't post the link). The problem is that when running rosdep it is telling me that there are missing resources such as roscpp and hector_sensors_description. Could someone kindly help me? Thanks a lot in advance and sorry for the long post. Again i'm fairly new to all this and I've been banging my head on this all week :/ Cheers, JP |
