very nice. Thanks.
Does the manual control work fine for you?

Hi
Yes I think it works very good. One of my wheel servos are a little slower then the other so I can't drive straight. This I think i can fix some day.
The only thing that is not so good is that it take all keyboard input from all consoles. If i leave manual on and got to another ssh session it keep on feeling the keystrokes and the rover runs around when i type. Miner issue because when you drive you drive and do other things.

:D :D :D

yes i have the same problem with manual control but that is inherent to the way i chose to implement it. The alternative would be to use some kind of game controller on usb. I don't have one so it isn't an option for me.

about the motors not running at the same speed, just go in the code and adjust one to run slower than the other until you find that it goes straight. Do it for the methods that control forward and backward movement.
That's how I solved my problem. Those motors are just dc so they are never going to run perfectly in sync and manufacturing inconsistencies will result in slightly different speeds for a given voltage.

Ok! I will adjust the code.
Qustion: If i light up some lights from the arduino script, will it crash sd card also?
What name do i use to access the chirp in python?

chirp does not exist in python yet. from arduino you can handle the pixels without affecting the pi.

did you also install the software for the pixels as mentioned in the guide? without it, you cannot communicate with the pixels daemon and it seems you are missing that daemon.
