Once the keyframes for the mechanical arm are set you can use the playback
controls to playback the motion for the mechanical arm.
To playback the animation using the playback controls
1 Click play on the TimeSlider playback controls to play the animation.
The mechanical arm animates over 180 frames. The cargo box does not
move because the weight attributes for the parent constraints are set to
zero and have not yet been set for the animation.
2 Click stop on the TimeSlider playback controls to stop the playback.
In the next steps, you set keyframes for the parent constraint weight attributes
so the cargo box is lifted, moved, and placed in the second location. You set
keys for the weight attributes on the parent constraint node.
To set keyframes for the parent constraint weights
1 In the Timeline, set the Time Slider to frame 1.
2 In the Hypergraph, select the node for the parent constraint directly
below CargoBox.
