mechanical logic mechanism
(OP)
Howdy folks!
I'm looking for a mechanical EX-OR gate concept. preferably based on turning elements (gears). The inputs and outputs will be rotating elements, so simplicity seems to dictate rotational logic, but linkages might be possible if they solve the riddle. any ideas are welcome.
I've done some googling on the subject, but to this point there is so much noise, thought I'd turn to my community to see if anyone has ideas or experience.
it may not be practical; the mechanism would be used in a lightweight handheld device. but I'd like to explore options. if it can be made to function, it would be awesome.
cheers

RE: mechanical logic mechanism
EX-OR has no meaning without an obvious mechanism. I would be willing to design one for you if you define a scope of work...
...and pay me.

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

.......A
Input Output
.......B
Input touches A and B
A and B touch each other
Output touches A and B
Input DOES NOT touch output.
A and B are attached to spring loaded buttons, so pressing the button lifts the gear out of plane with the others.
A0 B0 locks all the gears together
A0 B1 lifts B, so input rotates A which rotates output
A1 B0 lifts A, so input rotates B which rotates output
A1 B1 lifts A and B, so input has no effect on output, they can both spin free.
The only inconsistency is that A0B0 is locked, and A1B1 is free. This could be solved with an additional spring on the output gear, that moves output out of plane, into a locking position against a pin in the case, when neither A or B are applied. The output spring would be lighter than the A or B springs, to avoid locked if one or both A/B are in 0 position.
It is much easier than it sounds, trust me.

It's always something, and I was doing so well...

IRstuff,
I am looking to compare and transmit rotational motion. (low torque, low speed)

For my application, I may be able to get away with simply a subtraction gate.
