A GPU-based efficient pipeline for dexterous grasp synthesis built on cuRobo, proposed in [ICRA 2025] BODex: Scalable and Efficient Robotic Dexterous Grasp Synthesis Using Bilevel Optimization.
Project page ｜ Paper ｜ Dataset ｜ Benchmark code ｜ Learning code
- Grasp Synthesis: Generate force-closure grasps for floating dexterous hands, such as the Shadow, Allegro, and Leap Hand.
- Trajectory Planning: Plan collision-free approaching trajectories with the table for hands mounted on robotic arms, e.g., UR10e + Shadow Hand systems.
- Efficient: Capable of synthesizing millions of grasps per day using a single NVIDIA 3090 GPU.
- Generalizable: Supports different hands and a wide range of objects.
Some projects make modifications on our BODex pipeline to synthesize large-scale datasets of grasping poses, such as DexGraspNet 2.0 and GraspVLA.

Install git lfs: Before
git clonethis repository, please make sure that the git lfs has been installed bysudo apt install git-lfs. -
Install the Python environment:
conda create -n bodex python=3.10
conda activate bodex
conda install pytorch==2.2.2 pytorch-cuda=12.1 -c pytorch -c nvidia
pip install -e . --no-build-isolation
pip install usd-core
conda install pytorch-scatter -c pyg
conda install coal==3.0.1 -c conda-forge # https://github.com/coal-library/coal
pip uninstall numpy
pip install numpy==1.26.4
cd src/curobo/geom/cpp
python setup.py install # install coal_openmp_wrapper
- Prepare object assets: Download our pre-processed object assets
DGN_2k_processed.zipfrom Hugging Face and organize the unzipped folders as below.
src/curobo/content/assets/object/DGN_2k
|- processed_data
| |- core_bottle_1a7ba1f4c892e2da30711cdbdbc73924

Alternatively, new object assets can be pre-processed using MeshProcess.
- Synthesize grasp poses: Each synthesized grasping data point includes a pre-grasp, a grasp, and a squeeze pose.
# Single GPU version
CUDA_VISIBLE_DEVICES=7 python example_grasp/plan_batch_env.py -c sim_shadow/fc.yml -w 40
# Debugging. The saved USD file has the whole optimization process, while the intermediate gradient on each contact point is denoted by the purple line.
CUDA_VISIBLE_DEVICES=7 python example_grasp/plan_batch_env.py -c sim_shadow/fc.yml -w 1 -m usd -debug -d all -i 0 1
# Multiple GPU version
python example_grasp/multi_gpu.py -c sim_shadow/fc.yml -t grasp -g 0 1 2 3
We can also synthesize approaching trajectories that are collision-free with the table for hands mounted on arms, e.g., UR10e+Shadow Hand systems.
# Single GPU version
CUDA_VISIBLE_DEVICES=7 python example_grasp/plan_mogen_batch.py -c sim_shadow/tabletop.yml -t grasp_and_mogen
# Multiple GPU version
python example_grasp/multi_gpu.py -c sim_shadow/tabletop.yml -t grasp_and_mogen -g 0 1 2 3
On a single GPU, the grasp synthesis supports parallizing different objects, but the motion planning only supports parallizing different trajectories for the same object.
- (Optional) Visualize synthesized poses:
python example_grasp/visualize_npy.py -c sim_shadow/fc.yml -p debug -m grasp
- Evaluate grasp poses and filter out bad ones: please see DexGraspBench.
