A typical industrial robot has a form and function suggestive of a human arm. Does that mean the robot gripper ought to work like human fingers or a human hand?

This video demonstrates an alternate concept for robot gripping. The “Versaball” from Empire Robotics uses the compression of granular material to achieve its gripping force. This demonstration of the gripper on a robot arm from Universal Robots illustrates the strength, precision and control of the grip, not to mention its versatility, by lifting and relocating objects including a weight, a brick and a light bulb.
