Each one has a small fuzzy logic brain that decides when to start, walk, turn away from the edge of the field and stop. The motion itself comes from motion capture data of the <a href="http://mocap.cs.cmu.edu/">CMU Graphics Lab</a>: a real person walking, recorded at 120 frames per second. The field has waves, so the feet are put on the ground with inverse kinematics (IK).</p>
