3DSGrasp: 3D Shape-Completion for Robotic Grasp

no code implementations2 Jan 2023 Seyed S. Mohammadi, Nuno F. Duarte, Dimitris Dimou, Yiming Wang, Matteo Taiana, Pietro Morerio, Atabak Dehban, Plinio Moreno, Alexandre Bernardino, Alessio Del Bue, Jose Santos-Victor

However, in practice, PCDs are often incomplete when objects are viewed from few and sparse viewpoints before the grasping action, leading to the generation of wrong or inaccurate grasp poses.

Learning at the Ends: From Hand to Tool Affordances in Humanoid Robots

no code implementations9 Apr 2018 Giovanni Saponaro, Pedro Vicente, Atabak Dehban, Lorenzo Jamone, Alexandre Bernardino, José Santos-Victor

One of the open challenges in designing robots that operate successfully in the unpredictable human environment is how to make them able to predict what actions they can perform on objects, and what their effects will be, i. e., the ability to perceive object affordances.
