To pose the mechanical arm you select either the ArmControl or SwivelBase
nodes and set a keyframe depending on which component you want to pose:
ArmControl controls the movement of the mechanical arm.
SwivelBase controls the rotation of the arm.
CargoBoxs position is based on the parent constraint weights.
Animating an IK system
The animation sequence occurs over a 180 frame period. Before you begin to
set keyframes you set the playback range in the Animation Timeline/Slider.
To set the playback range in the Time Slider
1 In the Animation Time and Range Slider, set the following start and end
times for the animation:
Playback Start Time: 1
Playback End Time: 180
To simplify the keyframe workflow, you first set keyframes for the mechanical
arm, and then set keyframes for the weight attributes of each parent constraint
for the cargo box.
To set keyframes for the mechanical arm
1 In the Timeline, set the Time Slider to frame 1.
2 Select only ArmControl.
