Electromechanical Mating Interface Design
Note: Please refrain from jokes about sex, I'd like some serious answers if possible...
For my project I'm looking at designing a simple electromechanical interface for charging batteries. Specifically to have an autonomous robot be able to drive into something, have a way to align itself, and be able to charge.
Now the simplest way I have thought of is to grab a chunk of PCB and use it like a credit card slot. Then have the little sprung battery sliding contact thingo's (as can be seen in sim card slots, phone battery slots, etc...) inside to make contact.
Where I am a bit lost here is where to start with the physics of this. I have a feeling that the kero's might be able to steer me in the right direction.
I plan on designing so that horizontal misalignment can be ignored (say within 30 degrees). I know the maximum height misalignment that can occur. What I envisage is the requirement of one or two teardrop shaped curves to be able to align the PCB and the final sliding parallel.
Where do I start to look for these curves? I'm thinking that they will probably be an e^(x) or ln(x) from intuition...
Will try to do a quick cad of what I think it should look like, but what I'm after is how to make maths proofs or if they already exist...
Cheers,
