2014-09-17 15:32:06 -0600 | asked a question | Check on a rostopic programatically? I've tried searching for this but have been unsuccessful so far. Is it possible to see a topic's value, programatically? Basically, I need the functionality of rostopic echo, but I need to add it to my code. It's a topic that I created myself, so I can't just create a client and call a service... And I also do not want to subscribe to the topic and create a callback function. I just want to know the topic's value at a given point in my code. Is this possible? |

2014-09-15 17:04:11 -0600 | edited question | How can you fly the plane provided in plane_demo.world? I have created a ros node that takes inputs from the keyboard, to distinguish between going forward/backward, turning left/right, and going up/down. I can control the forward/backward easily (I just publish a twist message with the linear x component set to either a positive or negative number). I cannot figure out how to control the other things, though. To turn the plane, I allow wing 5 (vertical stabilizer, which controls yaw) to revolve around the z axis, and I publish twist messages to that link. This "works," in that I can clearly see wing5 rotating around the z axis. Now, logically, this should affect the direction that the plane travel but I dont understand how to implement that. For example, I tried setting wing5 to rotate, and then setting the plane's linear x velocity... however, this just moves the entire model in the +x direction, instead of moving in a direction that makes sense with the way wing5 is positioned. How do I control the plane's pitch and yaw? I see videos on youtube by John Hsu, flying this model around, so I know it has been done. Any help would be appreciated. |
