2014-08-06 09:20:39 -0500 marked best answer Starting New Project with Airplane Platform

I am working on a personal project in which I want to write a ROS package that can send messages to control the flight of an airplane (ex. Venture, Flyin' King, etc.) with the works: ailerons, rudders, elevators, etc. Is it possible to develop a ROS package for this sort of platform? Has any work been conducted on similar vehicles that could possibly be used as a guide? If not, what would be a good starting point for this type of project?

Thanks in advance.

Thanks a lot. The device I was considering using to control the motors was a Piccolo autopilot. Hopefully it will work in a similar fashion to an ardupilot.

2014-07-03 14:06:34 -0500 commented answer Pioneer P3-AT Doesn't Move - ROSARIA

Found my issue. I checked the rostopic list and found in my case /cmd_vel should have been /RosAria/cmd_vel. I changed it in my program to the correct topic name as well, and the robot moves now. Really silly mistake on my part, thanks a lot!

2014-07-03 11:41:40 -0500 asked a question Pioneer P3-AT Doesn't Move - ROSARIA

I have a concern regarding getting the Pioneer P3-AT to move. I have rosaria successfully installed, and I'm running on GROOVY. I run roscore in one terminal. Then I start rosaria in a second terminal and I receive the following:

viki@ROS:~/catkin_ws$ rosrun rosaria RosAria _port:=/dev/ttyS0

'[ INFO] [1404333854.139017779]: RosAria: publishing new motors state 1.

This is my issue,I am attempting to move the robot. I have tried the following command

rostopic pub -r 10 /cmd_vel geometry_msgs/Twist '{linear: {x: 0.1, y: 0.0}, angular: {x: 0.0, y: 0.0, z: 0.0}}'

no errors are displayed, but the robot doesn't move.

I then saw a similar post with a different model pioneer so I followed one of the suggestions and removed the readParameters() function from RosAria.cpp and received the following when I ran RosAria again:

viki@ROS:~/catkin_ws$ rosrun rosaria RosAria _port:=/dev/ttyS0

I then tried to run the above rostopic command again a but again did not work.

I have also written a program that is intended to move the robot as well. That program compiles fine and runs, but again the robot doesn't move, with and without the readParameters() function. Do I have any calibration settings are not properly set? Any guidance would be greatly appreciated.

2014-06-05 13:23:16 -0500 asked a question Razor.launch fails to launch (Razor 9DOF)

I am trying to test the driver package for Razor IMU 9DOF (Degree of freedom) sensors board based from this site: http://wiki.ros.org/razor_imu_9dof . I have installed Arduino and confirmed that it is working, as well as the python visual package. I installed wine v1.4 to get the python visual package working. After downloading and "rosmake"-ing the razor git repository without errors and running the command "roslaunch razor_imu_9dof razor.launch", i get the following error:

viki@ROS:/home/paralax2$ roslaunch razor_imu_9dof razor.launch
WARNING: unable to configure logging. No log files will be generated

Done checking log file disk usage. Usage is <1GB.

Invalid tag: Cannot load command parameter [rosversion]: command [rosversion roslaunch] returned with code [1].

Param xml is < param command="rosversion roslaunch" name="rosversion"/>

Are there any prerequisites that I may be unaware of? Why are the scripts unable to configure logging? Any guidance would be greatly appreciated.

I'm in the process of running catkin_make, but right before make is successful, I am receiving the following error with a gradle plugin:

Since the error mentioned permission being denied to the folder, I tried changing the permissions. I even used "chmod -R 777 filename(s)" but when I used catkin_make, I still received the same error.
Are there any possible workarounds or fixes for this issue? Any guidance would be greatly appreciated.

Sorry for the newb question, but when you say "virtual-machine-name" are you referring to the name given according to the initial VirtualBox start menu, which in my case would be "ROS Groovy Galapagos"?

Also should my ROS_MASTER_URI also be http://HOST_IP_HERE:11311/ ? Do I change it as well or leave it as it is? Whenever I change that parameter to include the host ip, I get the following: ROS_MASTER_URI [http://.......:11311/] host is not set to this machine

Thanks!

2014-04-07 11:42:29 -0500 asked a question ROS Sensors Driver Android Application Issue

I am trying to use the ROS Sensors Driver application for android devices, but have been unsuccessful in my attempts to get the app to work. Does the android_sensors_driver work on a virtualbox version of ubuntu running ROS? I have followed the directions exactly how they are stated here: http://wiki.ros.org/android_sensors_d... but I am not able to successfully get ROS to recognize android-sensors-driver as a node. According to the virtualbox wired connection, my IP address is 10.0.2.15. I have tried the following

http://10.0.2.15:11311/
http://ROS:11311/ because ROS is displayed when roscore is running
http://10.0.2.2:11311/ because of a suggestion on an online forum

but nothing seems to work. Any guidance would be greatly appreciated.
