Core Responsibilities

Human Pose Estimation

• Design and optimize hand pose estimation pipelines supporting accurate joint angle extraction from teleoperation data collection
• Build full-body pose estimation systems for motion capture and teleoperation action annotation ground truth generation
• Research and apply vision-based pose estimation methods (markerless) to reduce data collection costs
• Fuse pose estimation outputs with robot joint angle data to generate consistent training annotations

Robot Perception & Calibration

• Design and maintain intrinsic/extrinsic calibration pipelines for multi-camera arrays (factory calibration + online recalibration)
• Build visual SLAM / V-SLAM systems supporting real-time localization and scene reconstruction on data collection platforms
• Implement hand-eye calibration between cameras and robot end-effectors
• Develop temporal alignment solutions across multimodal sensors (cameras, IMU, data gloves, force sensors)

Perception Model Training & Deployment

• Train and iterate on perception models including object detection, instance segmentation, and 6DoF pose estimation
• Optimize model inference using TensorRT / CUDA for real-time performance on robot embedded platforms
• Write custom CUDA kernels for low-level acceleration of perception tasks
• Design evaluation metric frameworks for perception models; continuously track the relationship between model performance and data quality

End-to-End Loop from Data Collection to Model Delivery

• Contribute to the design of automated annotation pipelines that convert sensor data into structured training labels
• Build Auto QA modules to filter low-quality data including anomalous frames, failed demonstrations, and sensor dropouts
• Collaborate with ML engineers and data infrastructure teams to ensure perception output formats meet downstream VLA model training requirements
• Establish feedback mechanisms linking perception accuracy to model training outcomes, continuously improving annotation quality
