|A beautiful mess of cables and LEDs|
I still got a few cables to connect for the speaker and electronic compass, and give power to the H-Bridge. Also maybe the compass circuit can be directly connected to the GPIO of the Raspberry Pi. That would free up some pins(and memory) on the Arduino-board.
The webcam and USB-hub remains to be permanently attached on the topmost layer. I think I will use double sided tape. The cable that connects the webcam is very much too long and adds up to the weight of the robot. A nice thing with the USB-hub I use is that it has got individual power buttons, so I can switch on and off different hardware during programming.

More test will have to be done to test the Sonar and IR, but I think I will need to dissemble the robot first in order to attach those cables properly.
