Why do we humans have 5 fingers on each hand? It’s a question which you probably rarely think about. But, as roboticists, it’s a vitally important one to ask as we decide how many fingers to give a robot. Needlessly adding extra fingers increases the cost of a robotic system, reduces efficiency and complicates the control unnecessarily. However, some roboticists believe that robot hands should be anthropomorphic (human-like) to complete tasks as well as a human would. Should robotic hands have 5 fingers just because our hands do? In this post we explore how many fingers are really necessary and which factors are most important when choosing how many fingers to give a robot hand.
