Comments on CHRONO example robot_delta_motor.r3d

Actuators which impose motion.

What to do: load the file, open the control panel, press the play button on the animation timeline (watch at least 6 seconds of simulation!).

Here you can see the simulation of a 3 degrees-of-freedom (3DOF) parallel robot, a novel 'Delta(tm)' manipulator which is used mainly for fast pick-and-place operations.

This time, the robot is moved by three motion laws of the three linear actuators (see the 'd(t) extension' graphs in their property windows).
One may ask: how did we manage to draw these three graphs for imposing variable length to the actuators? Tha answer is that we previoulsy performed a IK simulation with actuators in 'learn mode', as shown in the previous example 'robot_delta_learn.r3d .
