Talking Re: Minibot switches and soft landings

Secondly, how do you make the minibot come down the pole to a "soft landing"? I've read that some teams are using reduced power on the motors to provide a braking action after the top sensors is reached. How is that done (eg. my switches are only on and off, no 1/2 power option) and is there a risk of burning up the motors?

Thanks.

Here is a little tip. McMaster Carr sells "Manual Reset limit switch" Part # 7336K51. Works like a charm. This will also allow you to create this circuit with EASE.

This is exactly how our minibot is wired....
