Hi. I am building a robot for my final project. It needs to turn left/right and goes up/down. I have already wrote a software in CVI but it is manual. I am controlling the motors by parallel port. I have a usb web cam that i put on it and i can see from it. The thing is it needs to make all movements all alone. It has to follow an object which is in motion and send pulses from parallel port. Please help!!!!
