Re: [FTC]: Cryptobox Detection
I am 2000% spitballing here. Haven't tried it, probably won't work, but the advice was free and worth every penny.
Thought 1) A whisker kind of switch would let you bump into each extrusion as you drive or strafe past.
Thought 2) Design in some kind of alignment widget (maybe thick scrap lexan, maybe euroboard, maybe 3D printed, maybe on a servo to pivot away) that lets you nestle up against a known part of the Cryptobox. Get close from encoders, drive in slowly to locate yourself using the widget, then run your left/center/right routine off of that location.
