Intro 8/10
After finishing my Easy Robot, I designed a paper circuit that uses the same robot base but with different controls: Two light sensors "look" at the screen. Black/Dark means stop the motor on this side. White/Bright means start the motor. To control the motors, basic transistors are enough! No microcontroller, no hardware programming needed. Slide in the phone and you are ready to go.
There are 3 different versions now: Paper Circuit, Breadboard, and PCB (WiP together with @maroveTimo )

Two hands using a smartphone with an interface having to sliders. In the background is a DIY robot looking like a smartphone with wheels. The first smartphone in the foreground is controlling the motor speeds of the robot.

A DIY robot that looks like a smartphone on wheels. The upper half of the screen is visible showing a blue face. The lowerpart is hidden by a breadboard with some electronik components.
The components are two mosfets that controll two motors. The mosfets are switched on/off by two lightesonsors that are bent to the smartphone screen (hidden by a sheet of paper to protect it from light)

a laptop screen showing a block based programming envoronment (MIT App Inventor). To the right of the screen is a smartphone robot looking like a smartphone on wheels with an orange cardboard/paper base.

a DIY smartphone robot looking like a smartphone on wheels. The upper part of the screen shots a blue face with some controlls reading "test your motors: motor 1, motor 2" there are two switches to turn on/off the motors. The lower part of the smartphone screen is hidden behind a PCB with various electronic components on it: tw Mosfets, resistors, an LED and an on/off switch. Two light sensors are mounted to the back side of the PCB so that they can see the screen.
