Final animation&VFX
Cause I really, really love this rigging course by Nick. Usually, I also like to learn about robots and different rigging methods, so this blog will summarize the 3 ways of rigging the robotic arm I learned this semester.
Summarize the three rigging methods.
1:Use Joint+IK+Curve & pole vector +point+orient constrain for rigging
Create Joints – create IK handle – create locator – control knee joint with Twist – connect locator and IK handle with pole vector – create curve – use curve and IK handle to constrain displacement with point – curve lies in the joint of the forearm to establish orient constraint to control rotation -Finish
Use loc to control the joint direction, use curve to control the upper arm and forearm, hand.
2:Use hierarchical relationships and parent constraints
1:clean hierarchical relationships
2:control the group point
3:set curve
4:set parent constrain -to every group
5:set curve group-to control every poly modeling
3:Use node to establish constraints
use the node editor to control the y-axis of the curve and to control the rotation details by adjusting the object’s rotation angle and
inputting and outputting the maximum and minimum values
