Abstract: A method and system for determining the position and orientation of parts and components of a humanoid robot using a body self-perception model (BSPM). The BSPM executes on onboard processors and receives image data from cameras mounted in the robot's head and on or near its hands. The BSPM processes the image data to detect and localize keypoints on the robot's own components and determines six-degree-of-freedom poses therefrom. The determined poses are provided to an onboard AI system that generates motor commands in a closed-loop control cycle. The BSPM may dynamically weight keypoint-based and holistic pose estimation based on occlusion degree, express poses using a delta SE(3) representation, and output uncertainty estimates that modulate control behavior. The system may fuse camera data with data from inertial measurement units, joint encoders, or other sensor modalities to produce position estimates exceeding the accuracy achievable by any single sensor alone.
