Figure A2. Robot imitation of human right-arm motion (left, human motion; right, robot motion) and result graph of each motion with the manual measurement dataset and inverse kinematics dataset, trained for 5,000 epochs: (a–c) right-armmotion shape (walking-jumping-greeting), (d–f) right-arm signal answer with inverse kinematics, (g–i) right-arm signal prediction with inverse kinematics, (j–l) right-arm signal answer with manual measurement, and (m–o) right-arm signal prediction with manual measurement. The x-axis represents time, and the y-axis represents the angle.
