Robots are already working alongside humans. They have safety features to protect human workers. Disney’s soft robotic hand and arm system is also interesting. It is a 6 DOF arm with two air-filled force sensing modules that absorb impact passively. The arm has an inflated outer cover that encloses its mechanism.
The hand is 3D printed with air-filled, force-sensing fingertips. The above video shows how this robot arm can gently grasp items with its force sensing fingers.
