Bio-inspired Robotic Hand
The human hand is such a complex and sophisticated tool compared to any other mechanical structure. In this research bioinspired aspects of the joints and tendon-driven mechanisms are studied to expand the coverage and improving the functionality of the prosthetic and the robotic hands.
Also, integrating tactile sensors into robotic applications is still a challenge because of sensor interconnection and various form factors. This study proposes an integrated design of a multi-joint robotic finger with magnetic synapse sensors inspired by the human’s joint structure and synapse system. The robotic fingers integrated with a high-sensitivity sensor array can grasp objects with various shapes and compliance (i.e., artificial flowers, paper cups, and wine glasses) without damaging the objects using tactile feedback.
