ROS doesn´t run into NAO robot.

edit

Hi, I am using the newer Nao. I have installed ROS electric (desktop) over ubuntu 10.04 with the atom toolchain 1.12.5. Today it compiles onto the pc. Buuut, ROS still doesnt run over the NAO. I have copied all the ros files from pc to nao via ssh. I obtain that:

nao [0] ~/ros $ ls
electric  setup.sh

nao [0] ~/ros $ /home/nao/ros/setup.sh
-bash: /home/nao/ros/setup.sh: Permission denied

nao [err 126] ~/ros $ source /home/nao/ros/electric/setup.bash
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
ImportError: No module named yaml
rospack could not be found, you cannot have rosbash features until you bootstrap ros

nao [0] ~/ros $ roscd
-bash: roscd: command not found

nao [err 127] ~/ros $

Thanks.
