Changelog
Version 0.6.3
Changes in default behavior
- Increased default collision cache to 50 in RobotWorld.
- Changed
CSpaceConfig.position_limit_clipdefault to 0 as previous default of 0.01 can make default start state in examples be out of bounds. - MotionGen uses parallel_finetune by default. To get previous motion gen behavior, pass
warmup(parallel_finetune=False)andMotionGenPlanConfig(parallel_finetune=False). - MotionGen loads Mesh Collision checker instead of Primitive by default.
Breaking Changes
- Renamed
copy_if_not_nonetoclone_if_not_noneto be more descriptive. Nowcopy_if_not_nonewill try to copy data into reference. - Renamed
n_envsin curobo.opt module to avoid confusion between parallel environments and parallel problems in optimization. - Added more inputs to pose distance kernels. Check
curobolib/geom.py. - Pose cost
run_vec_weightshould now be[0,0,0,0,0,0]instead of[1,1,1,1,1,1]
New Features
- Add function to disable and enable collision for specific links in KinematicsTensorConfig.
- Add goal index to reacher results to return index of goal reached when goalset planning.
- Add locked joint state update api in MotionGen class.
- Add goalset warmup padding to handle varied number of goals during goalset planning and also when calling plan_single after warmup of goalset.
- Add new trajopt config to allow for smooth solutions at slow speeds (
velocity_scale<=0.25). Also add error whenvelocity_scale<0.1. - Add experimental robot image segmentation module to enable robot removal in depth images.
- Add constrained planning mode to motion_gen.
BugFixes & Misc.
- refactored wp.index() instances to
[]to avoid errors in future releases of warp. - Fix bug in gaussian transformation to ensure values are not -1 or +1.
- Fix bug in ik_solver loading ee_link_name from argument.
- Fix bug in batch_goalset planning, where pose cost was selected as GOALSET instead of BATCH_GOALSET.
- Added package data to also export
.sofiles. - Fixed bug in transforming link visual mesh offset when reading from urdf.
- Fixed bug in MotionGenPlanConfig.clone() that didn't clone the state of parallel_finetune.
- Increased weighting from 1.0 to 5.0 for optimized_dt in TrajEvaluator to select shorter trajectories.
- Improved determinism by setting global seed for random in
graph_nx.py. - Added option to clear obstacles in WorldPrimitiveCollision.
- Raise error when reference of tensors change in MotionGen, IKSolver, and TrajOpt when cuda graph is enabled.
- plan_single will get converted to plan_goalset when a plan_goalset was used to initialize cuda graph.
- plan_goalset will pad for extra goals when called with less number of goal than initial creation.
- Improved API documentation for Optimizer class.
- Improved benchmark timings, now within 15ms of results reported in technical report. Added numbers to benchmark webpage for easy reference.
- Set
use_cuda_graphtoTrueas default fromNoneinMotionGenConfig.load_from_robot_config
Known Bugs (WIP)
- Examples don't run in Isaac Sim 2023.1.1 due to behavior change in urdf importer.
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.pyfor 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.pyto get the latest results. - Added
external_asset_pathto 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.shinstead ofbuild_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_joint2from<axis xyz="0 1 0"/>to<axis xyz="0 -1 0"/>infranka_panda.urdfto 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 setfinetune_dt_scale=1.05inMotionGenConfig.load_from_robot_config().
