Hello everyone i am new to this group, and i am writing because I have a problem with the interface for the ROS arducopter and also wanted to better understand the things that I am not clear on this subject.
I'm writing my graduation thesis, and I'm working on quadrorotor automated using the ROS, in the beginning I focused on Parrot AR.Drone 2.0, but now now I'm focused dell'arducopter.
My setup is Ubuntu 12.04 and ROS Fuerte, I own an AR.Drone 2.0 but NOT own a arducopter.
The first problem is with the interface roscopter, I followed all the instructions on http://code.google.com/p/roscopter/ but when I go to run the command:
nodes / roscopter.py - device = / dev/ttyUSB1 - rate = 57600 - enable-control = true
I get the error:
Traceback (most recent call last):
File "nodes / roscopter.py", line 7,
in import roscopter.msg
File "/ home / joe / fuerte_workspace / roscopter / nodes / roscopter.py", line 7,
in import roscopter.msg ImportError: No module named msg
The error is in the import roscopter.msg, and in fact inside the folder there is no msg file "roscopert.msg", i have to define it? in what way? how?
The second problem is that I have to figure out which topic should I write in order to execute the commands of TakeOff, Land, various movements etc ...
For example, with the 2.0 ardrone to make a takeoff was enough to send a message "std_msgs / Empty" on the topic "/ ardrone / takeoff" with the command on the terminal of ubuntu: rostopic pub -1 / ardrone / takeoff std_msgs / Empty How does works for the roscopter? Another thing that i want to figure is the role of MAVLink, and how does works .
Thank you very much in advance and sorry for my English
