FYI the SIG at http://wiki.ros.org/sig/NXT and now has 2 members.

@mdtobi, that is great. Yes I am using hydro. So what have you got to work so far?

I have made some progress on this set your .rosinstall to cat .rosinstall - git: {local-name: nxt_python, uri: https://github.com/chalko/nxt-python.git'} - git: {local-name: nxt, uri: 'https://github.com/chalko/ros-nxt.git'} then catkin_make And you will at least be able to run rosrun nxt_python nxt_test which on my machine says NXT brick name: Nick-NX Host address: 00:16:53:13:8C:D3 Bluetooth signal strength: 0 Free user flash: 61688 Protocol version 1.124 Firmware version 1.31 Battery level 7422 mV

I have stared making an attempt at https://github.com/chalko/ros-nxt/tree/catkinize However I am completly new to ROS. Any help would be appreciated. Or any pointers to others work.

I have made some progress on this set your .rosinstall to

- git: {local-name: nxt_python, uri: 'https://github.com/chalko/nxt-python.git'} 
- git: {local-name: nxt, uri: 'https://github.com/chalko/ros-nxt.git'}

then

catkin_make

And you will at least be able to run

rosrun nxt_python nxt_test

which on my machine says

NXT brick name: Nick-NX 
Host address: 00:16:53:13:8C:D3 
Bluetooth signal strength: 0 
Free user flash: 61688 
Protocol version 1.124 
Firmware version 1.31 
Battery level 7422 mV

Following the instructions at http://www.ros.org/wiki/groovy/Installation/Source#Building_the_catkin_Workspace

I run

./src/catkin/bin/catkin_make_isolated --install

But it fails. greping the logs yeilds

I played with building opencv by hand but never got only got it to work by not building the python part.

Note:

brew install opencv

works fine

I am running OS X 10.8.2 (12C60) And using xcode Version 4.5.2 (4G2008a)

I am stuck. my pthyon + cmake foo is too weak to know were to start.

So how can I get groovy to install opencv2 on my mac.

Per the instuction on installing ROS on OS/X I run

brew tap ros/fuerte

and get this result

I am unsure how to troubleshoot this. What should I try next?
