Journal Article
Ruiz Garate, V., Pozzi, M., Prattichizzo, D., & Ajoudani, A. (2018). A bio-inspired grasp stiffness control for robotic hands. Frontiers in Robotics and AI, 5, Article 89. https://doi.org/10.3389/frobt.2018.00089

This work presents a bio-inspired grasp stiffness control for robotic hands based on the concepts of Common Mode Stiffness (CMS) and Configuration Dependent Stiffness (CDS). Using an ellipsoid representation of the desired grasp stiffness, the algori... Read More about A bio-inspired grasp stiffness control for robotic hands.

Journal Article
Ruiz Garate, V., Pozzi, M., Prattichizzo, D., Tsagarakis, N., & Ajoudani, A. (2018). Grasp stiffness control in robotic hands through coordinated optimization of pose and joint stiffness. IEEE Robotics and Automation Letters, 3(4), 3952-3959. https://doi.org/10.1109/lra.2018.2858271

This letter presents a novel controller for robotic hands, which regulates the grasp stiffness by manipulating the pose and the finger joint stiffness of hands with multiple degrees of freedom while guaranteeing grasp stability. The proposed approach... Read More about Grasp stiffness control in robotic hands through coordinated optimization of pose and joint stiffness.

© 2017 IEEE. Object manipulation using hands is a compelling topic in which the interaction forces play a key role. These influence the stability of the grasp and the dexterity of the hand manipulation. A well-known technique to modulate these forces...
