Laptop PC robot base
If you wish to build a robot but you are not very familiar with microcontrollers, or your microcontroller just doesn't seem to have enough memory, why wouldn't you simply put your laptop on wheels?
Here you will see a 3-wheeled base for a robot who's brain is your notebook PC. With this configuration you will not end up without FLASH memory and you pretty much don't have any limitations. You can easily access: wifi, web camera, you can write your own image processing software and don't care how big it is, you can access it with your bluetooth phone and so on.
