I bulit a small robot and I want to add an "eye" to it.I use a PIC 16F876 and I want to use a USB webcam as the "eye".The camera has a OV518+ chip.The big problem I consider that is the USB protocol,especially host programming.
Does enybody have worked to such a project?Or with USB protocol?I would appreciate any help from you.

Try looking inside the webcam, you may be able to access the camera before it's converted to USB. Obviously the problem with using a PIC is going to be the lack of memory.

MicroChip make a special PIC (the 16C745) for USB use, which rather suggests that it's not very practical in software only, and I've not seen any suggestion it can act as a host either.
