Oorobot case

This is an alternate case for [Oorobot](https://github.com/Orange-OpenSource/oorobot) project. It has a cover and a place to store a phone charger that is used to power the robot. It doesn't have a place to hold a pen, privileging a place to put the battery.

Oorobot is an educational robot, to help children programming. you can program its movement with the onboard keyboard or android via bluetooth (if installed).
