NAO + ROS: walking : Howto? [closed]

edit

Hi everybody. I am trying to make my NAO walk using the nao_driver. But i can't get this thing working. It would be very kind of you, if someone can give me i hint on how doing so.

I tried several things. One in all i tried to publish a message to /cmd_vel

rostopic pub -1 /cmd_vel geometry_msgs/Twist '{linear: {x: 1.0, y: 0.0, z: 0.0}, angular: {x: 0.0, y: 0.0, z: 0.0}}'

publishing and latching message for 3.0 seconds

but nothing happens - the NAO does not move.

rostopic echo /cmd_vel

shows me that the value is correctly changed. But anyway the values in

rostopic echo /torso_odometry

stay the same and do not change.

Thank you for your help.

Edit:

I solved my problem: I forgot to enable the stiffness.

To do so just use (stiffness for whole body):

rosservice call /body_stiffness/enable "{}"

Now it works. :-)
