How to root a rare Android device?
Gaining root access could potentially lead to a reverse engineering of the device to locate an exploit and/or execute an exploit that could compromise the integrity of the system..

My concerns with this are SERIOUS !  

Your specific device has many Physical Capabilities being a robot fitted with a projector.  

Some famous hacks in the past have targeted people in a physical way, specifically I'm referring to a hack done on a Epilepsy foundation website that caused people visiting the site to have epileptic fits. 

If someone was to gain access to your device they could potentially cause harm, Real Physical Harm using the robot to perform physical actions that could directly or indirectly cause physical harm.


Showing flashing light's from the projector to cause epileptic fits !   
Walking around and causing dangerous situations like standing at the top of stairs.
Showing disturbing or hypnotic video using the projector.


The list goes on...

Please for the sake of your health, do not root this robot.
