hey people.
am hoping to get advice on an idea that I hope will act as both a "skin" and sensor for future robotics
so the pics are bad but I will run through the idea.
the black wire is the anode and is connected to a conductive sheet (most likely copper)
placed above it is a sheet with a good resistance value.
when you touch the top sheet the circuit to the 3 top wires (or four or however many you decide one) they calculate a rough circle(see the really rough circles I drew?) of where it "could" be connected to. a microcontroller then calculates the are that all these circles intercepts giving the rough location of the the connection.
I can think of a few uses for this but it has been a design that has been in my head for ages. the only issue I have is if you completely cover and object with this "skin" and can I keep them seperate AND allow them to make a closed circuit withouth and object getting in the way.
the other problem is what material would be best for the "skin"? it had to have an even resistive value to help the microcontroller identify the rough location.
I went against the touch screen technology as it does not locate pressure but infared (as far as I am aware) any help on this would be HUGELY appreciated
just thought of another issue, how can I make it so it won't act as a capacitor too?
