Exclamation Easing into top speed

Looking for some LabVIEW ideas on having more control over drive speed.

We have a Mecanum drive bot this year. Each wheel is directly driven by an AndyMark ToughBox with the standard gear ratio (12.75:1). The bot is probably in the 100 pound ballpark.

When we press "up" on the control stick, the bot really tries to take off. So much so that it sometimes lurches forward and almost lays some rubber.

Is there a way to slow it down? Or ease into the speed the same way a car does? Are the drivers simply pushing too hard too fast? When I drive, I try to really ease into the speed control stick, but some of the students just gun it. It almost looks like it's bad for the robot.

Is it common for teams to sorta ease into top speed? Is it not as bad for the bot as it seems in the shop? Thanks!
