★ Grasp Multiple Objects with One Hand

Yuyang Li   Bo Liu   Yiran Geng   Puhao Li   Yaodong Yang   Yixin Zhu   Tengyu Liu ✉  Siyuan Huang ✉ 

We propose MultiGrasp, a two-stage framework for simultaneous multi-object grasping with multi-finger dexterous hands. In addition, we contribute Grasp'Em, a large-scale synthetic multi-object grasping dataset.
