The classic Throw motion-law is a segment that has a Rise and Return, When there is a Dwell before and after, it will be a classic Dwell-Rise-Return-Dwell motion (DRRD).
In MotionDesigner, to design a Throw motion-law you must use two segments.
A classic Throw segment/motion-law has:
•zero velocity and acceleration at the start and end
•continuous acceleration at the mid-point
•an acceleration value at its mid-point that is not usually zero
When you use two Flexible-Polynomial segments to design the Throw, you can also control Jerk values and Jerk continuity at the start, end, and mid-point of the two segments.
These Throw motion-laws are examples only, with invented / suggested names:
A classic Asymmetric motion-law is one in which the acceleration phase of a Rise or Return segment has a different period to that of the deceleration
In addition to the design options listed above, you can also design an Asymmetric Throw motion if which the period of the Rise is different from the Return.
