a script intended to run 24/7 in the background, it will send Vector off of the charger if the Hue sensor detects a presence in the room, but only if the current time is between PLAYTIME_EARLIEST and PLAYTIME_LATEST. This is for use with the Anki Vector robot which is an awesome little bundle of joy with a full-fledged Python SDK and a ton of sm…
