2015-08-20 13:53:09 -0500 asked a question Robot randomly stops for a second between moving in a straight line and moving along a curve in gazebo

I am using ROS jade and Gazebo. I have two pioneer 3dx robots in simulation and they start out moving in a straight line. The robots should continue constantly moving, but switch from moving in a straight line to moving along a curve. The robot on the left does not pause, but makes the smooth transition. The robot on the right pauses for a second in between moving straight and moving along a curve. The code is the same for both robots, except for the fact that each code is talking to a different robot. Can someone tell me why this is happening? Thank you so much!

2015-08-14 10:10:57 -0500 asked a question Using sonar sensor in Gazebo for Pioneer3dx Model

Hello, I am using the pioneer3dx model in Gazebo from https://github.com/SD-Robot-Vision/Pi... and I couldn't find the robot publishing any sonar data. When I type rostopic list while the robot is moving in simulation, the topics that print out are:

/clock /cmd_vel /gazebo/link_states /gazebo/model_states /gazebo/parameter_descriptions /gazebo/parameter_updates /gazebo/set_link_state /gazebo/set_model_state /odom /p3dx/base_pose_ground_truth /p3dx/laser/scan /rosout /rosout_agg /statistics /tf

But when I look through each topic, I do not find any sonar data. I was wondering if I had somehow missed the sonar data, or the topic publishing the sonar? And if I didn't, how do I add sonar sensors to this model? Or is there already a model with the sonar sensors? Thank you so much!

2015-08-13 13:12:34 -0500 asked a question Using Gazebo Simulator with Pioneer3dx Model

I have written code that I have run on MobileSim simulator for the Pioneer3dx model, and it runs on the actual robot, which used RosAria. Now I am trying to use the Gazebo simulator, since I need to use the physics engine, but I am getting really confused. I have looked online and gone through the Gazebo ROS tutorials but I still am not quite clear on what I need to do. Can I use ROS Aria in Gazebo? If so, how? If not, is there anything special I need for gazebo? How will I convert the code I had written for the robot using ROS Aria to the format Gazebo needs (because my code subscribes to topics such as /RosAria/pose and /RosAria/sonar, which will not not exist when ROS Aria is not running)? I am sorry for the million questions!

Thank you so much!!!! It worked!

2015-08-12 20:28:54 -0500 asked a question Could not find a package configuration file provided by "controller_manager"

I am running ROS jade on an Ubuntu 14.04 OS and I am trying to connect the Gazebo simulator to ROS. I have followed the tutorials to connect Gazebo to ROS on the Gazebo website, and now I am trying to download the URDF of the Pioneer 3dx robot (since that is the robot I am using), but I am running into a problem. I have placed the URDF file from a github site into the src directory of my catkin_ws, but whenever I run "catkin_make" I always get this error:

CMake Error at /opt/ros/jade/share/catkin/cmake/catkinConfig.cmake:75 (find_package): Could not find a package configuration file provided by "controller_manager" with any of the following names:

controller_managerConfig.cmake
controller_manager-config.cmake

Add the installation prefix of "controller_manager" to CMAKE_PREFIX_PATH or set "controller_manager_DIR" to a directory containing one of the above files. If "controller_manager" provides a separate development package or SDK, be sure it has been installed. Call Stack (most recent call first): ua_ros_p3dx/p3dx_control/CMakeLists.txt:7 (find_package)

-- Configuring incomplete, errors occurred! See also "/home/tatum/catkin_ws/build/CMakeFiles/CMakeOutput.log". See also "/home/tatum/catkin_ws/build/CMakeFiles/CMakeError.log". Invoking "cmake" failed

I have looked online to find an answer to this problem but the answers posted do not help me. I think this has to do with the fact that the the other questions were based on the indigo distribution. Please help!!

I am running ROS Jade on Ubunutu 14.04 OS. I have been trying to follow the tutorials to connect the Gazebo simulator with ROS. I am getting a problem when I try to download the URDF file for the Pioneer 3dx model to use in simulation. Whenever I run "catkin_make" I always get:

This occurs when the URDF file that I have downloaded is placed into the src directory in my catkin_ws. I have looked online for help and nothing others have posted seems to work, and I think it might be because the other questions were using ROS indigo as the distribution. Please help!
