Re: Minibot Falling Solutions

Don't mean to self-quote here, but I had a thought earlier today and put it in the wrong thread.

This assumes a cutoff switch is designed into the MINIBOT as well.

That's why it reduces friction rather than creating full separation: just how much friction it reduces is completely customizable if you think it through. There's no magic to it; the best way to figure out the balance for a given MINIBOT is to prototype on a specific design. It's better (IMO) than relying on backdriving the motors (though it'd take away the 'innovation' of regenerative MINIBOT falling ) while also removing the need for other (heavier) concepts (like the NXT + sensors).
