Hello again…
Something weird happened few days ago…
EMO was searching for his home station, but couldn’t go to it.
So he turned off (normal…)
We put him back, and he charged normally.
But since, he doesn’t want to go out alone anymore.
But when he take him off by hand, he can go back to his home station, but think it’s his skateboard when he’s on it !!!
So new “problem” (it isn’t a real problem, but don’t have other word…)
Please tell me if it’s normal, or if you have a solution to propose 
Have a nice day all
