What is it about?
Designing an anthropomorphous mechanical hand is known to be a most complicated task. Through the motion analysis of a manipulation task we found new parameters to take into account, such as the influence of a wrist or the usage of a time-dependent PIP-DIP articulations coupling ratio throughout a manipulation task. We reproduced the object motion with our robotic hands to identify what improvements these hands need in order to be able to reproduce highly dynamical or fast human hand motions.
Why is it important?
The human hand is considered to be the most complex of all the external organs of the human body. Designing an exact mechanical copy might prove almost impossible today. Our mechanical hands are devoted to evolve in a human environment. We need to identify which design parameters need reviewing so that they can manipulate any object from the "everyday life" with high speed.
