DriveMyPhone is a project i have siting on my computer in digital format for the past 6 year now. The concept came around when i was working on my other robotic projects called MobileEarthRover One am MobileEarthRover Two.
I have finally had time to publish it, i did not do it before because of the lack of time (submitting an instructable requires a lot of time and effort), lately i have been too busy building and selling 3D printers at reprapalgarve.

The Drivemyphone concept has won two competition ideas, 'ideias em caixa 2010' and 'idea2product 2011 Portugal'. Keep in mind that it man not be so innovative now in 2106, but back in 2010 it had some potential.
The DriveMyPhone has also won venture capital funding, that did not go as planed. A patent for the model was also submitted, you can read it the attachment section below. All idea competition take in account not only the product but also the marketing and sales strategy, so that was also the reason it won, i will not enter in detail in this field becaus it is out of context here in instructables.
