Send Vector into a deep sleep for the night.
Put your required hours for Vector to sleep in the 'Hours_to_sleep = xx'
Vector will go about his normal behaviors until you touch his back sensor, he will then return to his charger, turn off his screen and sleep for the duration entered.
I recommend using crontab to run the script at the time you require, then all you have to do is touch his back pack before you go to bed.
