I am currently want to design a project, that is 3pi robot connect to raspberry pi and use usb camera to do object tracking. The other function maybe is use wireless mode to do remote control in android phone.
My question is that I dont know how to connect 3pi robot and raspberry pi. some people say use UART. Dose anybody do this project or connection before? Could you give me some idea?
PS: The reason why I not use arduino is that the process is so slow and SRAM is so small. I have to choose raspberry pi.
