The cheapest identification method (an alternative to RFID)
December 20, 2012
I am very beginner in robots making. I have an issue with my 2 cats (one of them). He eats to much and gets fat: when he finishes with his ration, he switches to another bowl:)
So I decided to build up an automatic cat feeder equipped with recognition system to analyse which cat is near the feeder. I have some ideas on mechanical matter of the device and need to learn a lot about electronic. But I have already stuck with the decision how the system will recognise the cats. I had an idea to make some kind of weight scales, but I thing this is not the way I should follow. Face detection system is also toщ complicated, if not impossible for me. So the best way I can see is to use something like RFID. I can't use RFID because the scanner price is too high, and I will need two of them (one for each feeder).
Can anyone give me an advice what will be the best in my situation?
Thanks in advance.
