Changelog

Version 0.6.2

New Features

  • Added support for actuated axis to be negative (i.e., urdf joints with <axis xyz="0 -1 0"/> are now natively supported).
  • Improved gradient calculation to account for terminal state. Trajectory optimization can reach within 1mm of accuracy (median across 2600 problems at 0.017mm).
  • Improved estimation of previous positions based on start velocity and acceleration. This enables Trajectory optimization to optimize from non-zero start velocity and accelerations.
  • Added graph planner and finetuning step to joint space planning (motion_gen.plan_single_js). This improves success and motion quality when planning to reach joint space targets.
  • Added finetuning across many seeds in motion_gen, improving success rate and motion quality.
  • Add urdf support to usd helper to export optimization steps as animated usd files for debugging motion generation. Check examples/usd_examples.py for an example.
  • Retuned weights for IK and Trajectory optimization. This (+ other fixes) significantly improves pose reaching accuracy, IK accuracy improves by 100x (98th percentile < 10 micrometers) and motion generation median at 0.017mm (with). IK now solves most problems with 24 seeds (vs 30 seeds prev.). Run benchmark/ik_benchmark.py to get the latest results.
  • Added external_asset_path to robot configuration to help in loading urdf and meshes from an external directory.

BugFixes & Misc.

  • Update nvblox wrappers to work with v0.0.5 without segfaults. Significantly improves stability.
  • Remove mimic joints in franka panda to maintain compatibility with Isaac Sim 2023.1.0 and 2022.2.1
  • Cleanup docker scripts. Use build_docker.sh instead of build_dev_docker.sh. Added isaac sim development docker.
  • Fixed bug in backward kinematics kernel, helped improve IK and TO pose reaching accuracy..
  • Changed panda_finger_joint2 from <axis xyz="0 1 0"/> to <axis xyz="0 -1 0"/> in franka_panda.urdf to match real robot urdf as cuRobo now supports negative axis.
  • Changed benchmarking scripts to use lock joint state of [0.025,0.025] for mpinets dataset.
  • Added scaling of mesh to Mesh.get_trimesh_mesh() to help in debugging mesh world.
  • Improved stability and accuracy of MPPI for MPC.
  • Added NaN checking in STOMP covariance computation to account for cases when cholesky decomp fails.
  • Added ground truth collision check validation in benchmarks/curobo_nvblox_benchmark.py.

Performance Regressions

  • cuRobo now generates significantly shorter paths then previous version. E.g., cuRobo obtains 2.2 seconds 98th percentile motion time on the 2600 problems (benchmark/curobo_benchmark.py), where previously it was at 3 seconds (1.36x quicker motions). This was obtained by retuning the weights and slight reformulations of trajectory optimization. These changes have led to a slight degrade in planning time, 20ms slower on 4090 and 40ms on ORIN MAXN. We will address this slow down in a later release. One way to avoid this regression is to set finetune_dt_scale=1.05 in MotionGenConfig.load_from_robot_config().

Version 0.6.1

  • Added changes to examples/isaac_sim to support Isaac Sim 2023.1.0
  • Added dockerfiles and notes to run cuRobo from a docker
  • Minor cleanup of examples
  • Added option to generate log with UsdHelper from URDF file (check examples/usd_example.py)
  • Fix typos in robot sphere generation tutorial (thanks @cedricgoubard)

Version 0.6.0

  • First version of CuRobo.
