Easing into top speed

Is there a way to ... ease into the speed the same way a car does? Are the drivers simply pushing too hard too fast?

You could try putting a low-pass filter or a rate limit on the joystick commands before passing them to the mecanum vi.

Always love how quickly I can get honest and knowledgeable input on C/D!

vhcook- We'll give that a try today, thanks. We tried something like that last year. Can't remember the results though...

WizenedEE- Our programmers haven't jumped into PID lopps yet. That's something we're considering for some off-season learning. We are done competing for the season. Getting the bot more under control is for some public demos we have coming up in the next month.

Ether- Those two ideas sound interesting. Can you elaborate on them please?
