Please give some more detail on your actual problem if you want more than generic troubleshooting.

When the robot run, in rostopic echo diagnostics it says first :

level: 0 name: hokuyo_node: /scan topic status message: Desired frequency met; Timestamps are reasonable. hardware_id: H1311945 values:

then after a while it says that the frenquency is to low And finally

level: 2 name: hokuyo_node: /scan topic status message: No events recorded.; No data since last update. hardware_id: H1311945

However when i use only the laser without the arduino (whithout moving my robot) it doesn't happen.

I'm going to suggest that this is hardware limitation... I believe you're overwhelming that poor little Arduino... They're not exactly meant to run with gigantic data arrays like Laser Rangefinders... Then the odometry and other topics on top of it just make it too much to handle.
