Over a three-month period, contributed to ucb-bar/IsaacLab by enhancing XR teleoperation performance and reliability for robotics simulation. Focused on tuning simulation parameters and introducing configurability for key factors to improve operator responsiveness, while updating environment settings for flexible performance tuning. Delivered frame rate optimization by constraining the simulation loop and stabilizing rendering cadence, targeting smoother teleoperation. Addressed runtime reliability by removing problematic environment variables and expanded teleoperation support for new robotic tasks, including dual hand tracking and Pinocchio integration. Work involved Python, YAML, and DevOps practices, with thorough documentation updates to ensure reproducibility and ease of adoption for users.
March 2025 monthly summary for ucb-bar/IsaacLab: Focused on stabilizing runtime reliability and expanding teleoperation capabilities for the GR1T2-Abs task. Delivered a reliability fix by removing the NV_PACER_FIXED_TIME_STEP_MS environment variable from the CloudXR runtime, addressing issues tied to the fixed-timestep flag. Implemented teleoperation support for the Isaac-PickPlace-GR1T2-Abs-v0 task by updating the teleoperation agent script and CloudXR documentation, enabling Pinocchio and dual hand tracking for improved robotic control. Documentation updates accompany the changes to ensure new capabilities are reproducible and easy to adopt.
