Motor Speed gradual/quadratic increse?

Is there a way to program a motor to drive so that as you control the robot with the analog sticks, the motor speed increases at a constant acceleration?

I know that the joystick already sorta does this, but is there a way for the program to make the motor move even slower while one minimally pushes the joystick Rx control, while still being able to go full speed? Are there subprogram any subprogram that i have to make?

Sure, you can.

Drag an RxInput block onto the flow chart and then click on the help button
when the dialog appears.
