Pi Droid Alpha is the best educational Robot Controller for the Raspberry Pi
I had a lot of great feedback from teachers on my RoboPi advanced robot controller for the Raspberry Pi, however most asked for a less powerful - and lower priced - alternative for simpler Robots. I listened :)
Pi Droid Alpha adds an L293D dual h-bridge motor driver, MCP3008 eight channel 10 bit analog to digital converter, and an MCP23S17 sixteen channel digital I/O expander to your Raspberry Pi and works with any model Raspberry Pi.

For entry level educational and hobbyist robots, I recommend Pi Droid Alpha as entry level robots normally do not require powerful motors that draw a lot of current.
Mikronauts robot controllers are supplied in kit form in order to make them more affordable – and to offer makers the satisfaction of building their own controller, for more pride in their robots.

Now I have to go to work on my shiny new Pi Droid Alpha based bot :)
