How Fast Can you Safely Climb?

Just an idea, but will likely never be implemented.

The issue would be if a team only had a motor keeping the robot up, it would crash to the ground immediately.

You could argue that it would also crash to the ground at the end of the match anyway if all they had was a motor holding it up.

It doesn't matter if the robot falls after the timer stops.
The rules say that as long as the button is pressed through time 0 and it is pressed for over 1 second, it will count. I'd therefore recommend that you run your winch a little more than the minimum requirement to make sure that even if it does begin to slip or unravel, the button will still be pressed enough to credit the points.

If you're referring to the robot damage, that could be a serious issue.
I talked about this with my sister and she said to use an airbag-type system to prevent robot damage. I would LOVE to see someone build an airbag-type system that is FRC legal.

Either way, I hope this helps.

My back of the envelope calculations tell me a 2.5 second 1-CIM climber at motor max power point is very doable. Half that for 2 CIMs.
