gmapping_distributed example on Kaya


I’m testing gmapping_distributed example on my Kaya.
Joystick example could run by help of @bluecamel.

But I am stuck in this gmapping_distributed example,
motor and joystick again.

Hardware config: v2
gmapping_distributed_kaya: camera is OK, but motor and joystick is NOT.
gmapping_distributed_host: gmapping window is not update at all

Could you let me know where to check?
