Robotics Challenges - Designing dexterous robot hands is a difficult problem [1] - Manufacturing these hands at scale is 100 times more challenging [1] - A human hand has 27 degrees of freedom (4 per finger, 5 for the thumb, and 6 for the wrist), making robotic replication complex [1] - Building a robot to manipulate objects like picking up a coin is a non-trivial task [1]
