Our project is an automatic paper "checker". b4 we can check the paper it has to be fed into the part of the machine where the sensors are. we would like to ask what type of motors would be ideal for such an operation. also how do you make the feeding continuous, that is, what do we need to do to make a feeder where you just place a stack of papers in the paper tray and it will be fed in continuously. can we do this in a purely mechanical way or is there a software we can use?
