Learning from Observation (LfO) for Robots via 3D Body Pose Estimation
Overview
This tutorial explains how robots can learn tasks like picking up and moving objects through Learning from Observation (LfO), using 3D body pose estimation. It details the process of converting human demonstrations into numerical data, transforming human motion into robot-compatible commands, and highlights the advantages of using standard cameras over motion capture systems.

“s. The AI analyzes the recorded footage and estimates the positions of human joints such as the shoulders, elbows, wrists, and hips. Google's MediaPipe Pose Landmarker can estimate 33 landmarks on the human body. When analyzing work movements of the right arm, the three points of the right shoulder, right elbow, and right wrist are particularly important. By representing each position with X, Y, and Z 3D coordinates,”

“to convert the coordinates based on the robot's base. After that, the angles of each joint are calculated so that the robot's end-effector reaches the target position and orientation. This calculation is called inverse kinematics. For example, in a 6-axis robot, six joint angles are calculated to generate movement targets for each motor. However, the calculation must also take into account joint range of motion, spe”

“the actual machine. In more advanced systems, it is also possible to train VLA models that link vision, language, and action using multiple work videos as teaching materials. This allows for the development of robots that can adjust their work methods according to the position of parts and surrounding conditions, rather than just replaying recorded movements. Conclusion through 5 slides A human demonstrates a task, a”
