joystick control

[turtle]

hi ive been thinking of an easy way to use a joystick for speed control and turning, i didnt want to do to deep into the electronics side of things. heres a quick drawing ive done in paint (dont laugh lol) has anyone used something like this before so i could have a look before i start making my own.



i am going to use 2 joystick this is just one of them. as you can see from the picture the forward and back speed control come from the pots, and the left and right i was going to use the micro switchs to to cut out the left or right motor to make it turn.
but on the other joystick i am going to make one motor turn the other way to the other to make it turn really quick.
by doing it like this i can use a load of relays to make things simply plus have a bit of control. i hope lol.

this is the joystick i was looking at modifying

I've heard about people use the old arcade joysticks.. each position one relay just cross the motor supply wires and it goes in all directions with the joystick control.
I wanted to go via computer control but at the end i found out that a joystick is a much easier handling. I just go for the USB joystick Logitech 3D, so I have all buttons and the handle I need to control everything.
For me is and will be Joystick the Nr 1 control.
