CoRL 2026 Oral 🌟
A team led by Peking University introduced OpenDexGrasp.
It takes free-form language instructions, multi-view images, and 3D point clouds as input.
Then it directly generates a dexterous five-finger grasp pose.
For example, grip a hammer by its handle, not its head.
To train the model, the team built OpenDexVerse:
• OpenDex-Scale: 1.24M automatically generated grasp samples.
• OpenDex-Align: 27.42K human-teleoperated and transferred grasp samples.
The results:
In simulation:
62.96% functional grasp success on unseen object categories.
The DexGraspNet 2.0 baseline scored 43.22%.
On a real robot, it achieved a 72% success rate across 10 everyday objects, including brushes, shampoo bottles, umbrellas, and pitchers.
The baseline scored 59%.
It's also faster.
Traditional methods predict the graspable area first, then optimize the hand pose.
OpenDexGrasp generates the grasp pose directly.
Traditional pipeline: 2.84 s
OpenDexGrasp: 0.93 s
67% less inference time.
It's not perfect, though.
Thin or complex objects like keyboards, frisbees, and flower pots can still cause problems, including finger penetration and inaccurate grasp placement.
