2015-10-05 14:56:19 -0500 | commented question | What camera topic should be given to the navigation stack? what are you using in your launch files? |
2015-10-01 12:57:45 -0500 | answered a question | navfn planning through wall I don't see some parameters that I know of in costmap_common_params that would help you in the cost map: cost_scaling_factor and inflation_radius. I would throw these parameters in an inflation layer namespace. So it would look something like this in your .yaml file: There are plenty of other parameters you can add in to get the costmap working the way you need it to. I would do some research here and read up on what other parameters you may want to add in rather than using the defaults: http://wiki.ros.org/costmap_2d/flat and http://wiki.ros.org/costmap_2d/hydro/... |

2015-09-01 15:49:02 -0500 | asked a question | Can hector_quadrotor use the ROS navigation stacks? I have some software that uses navigation stacks for the turtlebot and work. I'm now transferring those files onto the hector_quadrotor and I'm having issues with the move_base file in the navigation stacks. Is the hector_quadrotor compatiable with move_base? Is there something I'm missing? I'm working with ROS Indigo and Ubuntu 14.04. |

2015-08-25 12:41:53 -0500 | answered a question | How to get hector_quadrotor to fly autonomously I was able to find two things after trial and error with a coworker. The Now I'm having issues with the time portion so I've started debugging that. If anyone else sees anything, please let me know! |

2015-08-24 15:39:19 -0500 | asked a question | How to get hector_quadrotor to fly autonomously So, still new to ROS and the debugging of the programs. I'm trying to make a program where hector_quadrotor flies up into the air, hovers, spins, and then continues to hover before going to the next task. I've gotten it to work with just forcing the functions through: With this working, I've been trying to figure out the publishers and subscribers needed to get the separate functions to work and have run into a snag with the publishing and subscribing: (more) |

2015-08-05 16:14:47 -0500 | answered a question | Spawning hector quadrotor crashes gazebo on indigo Have you tried making sure that all of the need files are downloaded for the demo? When I was running into building errors, I did Then hit the tab button till I got the list of all installed hector related packages (be careful not to remove anything). I was missing some of the packages so as soon as I But, the way your error is presented, you maybe missing the controller package for gazebo. |
2015-08-05 10:09:09 -0500 | commented answer | pr2_teleop not working with indoor simulator Yes, I'm sure I am on that terminal alone. And when /cmd_vel is echoed this is the response: WARNING: no messages received and simulated time is active. That would mean the source code is messed up and I'd have to dig to fix that, I think I went and tried the X-box controller and that made it work |
2015-08-04 19:11:39 -0500 | asked a question | pr2_teleop not working with indoor simulator I'm still new to ROS but I have gone through the hector quadrotor tutorial ( http://wiki.ros.org/hector_quadrotor/... ) and the indoor program comes up fine with no errors. Then I run: And the program goes just fine but when I hit keys on the keyboard, nothing happens to the quadrotor. I'm running on Ubuntu 14.04 LTS and ROS Indigo. If anyone could give me suggestions on what to echo or look into to fix the connection between the keyboard controller and the sim quadrotor, that would be fantastic. Thanks!! |
