i, working on a robot project that needs image processing. i thought if its possible to use a pc or mobile(android or ios) device instead of micro. so i know phidget is some kind of hardware that does the job for me. is it possible to use arduino as that IO for my device?

thank you for helping

What do you want the Arduino to do?

It does not have the power to do image processing. But if you do the image processing on a PC you could get the PC to send commands to an Arduino to control lights or motors.
