will this work on hydro or will I have to go back to fuerte? Also I added more detail about what is happening in the question. I have the spacenav folder downloaded from http://spacenav.sourceforge.net/

Added it in the post. Sorry I forgot to paste it in before

I am trying to connect a 3d space mouse to ros to publish to A dynamixel motor. I am following the tutorial ( http://wiki.ros.org/threeD_mouse )about how to start the 3d mouse but I keep getting this error. can anyone explain what I have done wrong?

[ rosmake ] rosmake starting...

when I run the rosmake command. I have downloaded the libraries it tells me to and have put them in my home directory. I am running hydro also.

When I run "rosmake spacenav" seen on this page ( http://wiki.ros.org/spacenav ) I get the error:

[ rosmake ] rosmake starting...
[ rosmake ] Packages requested are: ['spacenav']

[ rosmake ] WARNING: The following args could not be parsed as stacks or packages: ['spacenav']
[ rosmake ] ERROR: No arguments could be parsed into valid package or stack names.

also when I run "rosdep install spacenav_node" from here ( http://wiki.ros.org/spacenav_node/Tut... ) I get the error:

ERROR: Rosdep cannot find all required resources to answer your query
Missing resource spacenav_node

But I assume that is from the "romake spacenav" command is failing.

I am working through creating the meta controller in this tutorial http://wiki.ros.org/dynamixel_control... but when I run the code after coping into the correct files, i get this error. "Invalid roslaunch XML syntax: junk after document element: line 3, column 4" Can anyone explain how to fix this. I have never done anything with XML so I have no idea how to fix the error.

I am trying to control my dynamixel motor in real time. I have been using rostopic to do this but it still seems jumpy because of the 3 second latching. Are there any better ways to control the servos in real-time, or is there a way to disable the 3 second latching with rostopic?

What I am trying to do is move the motor back and forth with another interface and I was using rostopic but i needed to send a command faster than every 3 seconds. Is there a better way to give the motor position commands quickly?

When I follow this tutorial ( wiki.ros.org/dynamixel_controllers/Tutorials/CreatingJointPositionController ) and everything works like it should but when I run the command "rostopic pub -1 /tilt_controller/command std_msgs/Float64 -- 1.5" it says "publishing and latching message for 3.0 seconds" is there anyway to change that 3 seconds latching time to something else, say 2 seconds or 1 second?

I was working though the tilt_controller here: http://wiki.ros.org/dynamixel_control... and I was wondering how you give it a specific angle to go to? Because I can only have it twitch between roughly 180 and 190 degrees ccw from the base of the motor. I.e say I wanted to have it tilt at a 60 degree angle, what command would I give it?

I am trying to put my dynamixel mx-64 servo motor into wheel mode like it says in step 1 of this tutorial http://wiki.ros.org/dynamixel_control... can anyone explain to me how to put the motor into wheel mode on ubuntu?
