'RapidReturn 2' is Not available in the MotionLaw Selector The RapidReturn2' motionlaw is a Rise & Return motionlaw that is continuous in Velocity and Acceleration throughout. Construct it with two Flexible Polynomial Segments. The first segment is the 'Rise', and the second the 'Return'. Each segment is a 'mirror' of each other. Usually, the segments have an equal duration, but this is not necessary. Continuity at the MidPoint BlendPoint The Position is a maximum, and the Velocity is zero, the Acceleration is 'finite', but continuous. The Rise segment [below, in Blue] ends with a finite, negative acceleration. The Return segment [below, in Red] starts with the same finite, negative acceleration. There is acceleration continuity. The Jerk is discontinuous at the midpoint. [The Jerk is zero at its start an end]. The position graph makes a rapidreturn at the midpoint because there is a large negative, but continuous, acceleration at the midpoint. The motion from Rise to Return at the midpoint is more rapid than QuickReturn 1 and QuickReturn 2 and RapidReturn 1. Thus we call it a RapidReturn 2. Generally, this motion is not recommended.
