Course details

Learn to rig and animate a 3D robotic arm in CINEMA 4D. EJ Hassenfratz leads this project-based learning experience, which relies on C4D's inverse kinematics (IK) tools. First, you'll prepare the model hierarchy for animation, before adding joints and applying an IK tag that transforms your joint system into an IK chain. Then you'll animate the entire rig and use constraints tags and Xpresso data to control all the moving parts in the arm. Last, EJ shows you how to render the project and import it into After Effects for further refinement.

Preparing the Model for Inverse Kinematics (IK)

  • Describing the model setup and hierarchy
  • Understanding IK and forward kinematics

Creating the IK Chain

  • Introducing joints
  • Applying an IK tag
  • Freezing and resetting transformation values

Adding Animation Controls

  • Adding a Constraint tag to keep parts aligned
  • Creating Xpresso user data to control rotation
  • Constraining a part's movement range with the Range Mapper node

Animating the Robot Arm

  • Setting up the rig for animation
  • Animating the arm movement using keyframes
  • Using position, scale, and rotation constraints to place a logo element

Rendering and Finishing in After Effects

  • Setting up to render by adding Compositing tags and multipasses
  • Importing the rendered project into After Effects
