Bimanual Grasp Synthesis for Dexterous Robot Hands
Yanming Shao, Chenxi Xiao·November 24, 2024
Summary
BimanGrasp algorithm optimizes bimanual grasp poses for dexterous robot hands, addressing handling of large, heavy objects. It synthesizes grasp poses through stochastic optimization, verified in Isaac Gym physics simulation. BimanGrasp-Dataset, the first large-scale synthesized bimanual grasp pose dataset, comprises over 150k verified grasps on 900 objects. BimanGrasp-DDPM, a diffusion model trained on this dataset, achieves a 69.87% grasp synthesis success rate, significantly accelerating computational speed compared to the BimanGrasp algorithm.
