A robot idea

I have an idea to build a robot who connect two popular devices:

- Raspberry Pi

- ArduinoMega

Raspberry Pi is great platform for building advanced  system on a linux platform. We can easy add wifi/internet services, video streaming, audio advanced systems.

ArduinoMega has other adavantages, board has many input/output digitals and analogs. There are a lot of pages describing how to connect various devices.

  

I would like to combine the advantages of these two devices.

Scheme of the robot.
