Flexible gripper
The American gripper manufacturer Soft Robotics offers a gripper that can be quickly and easily assembled to grip a wide variety of parts. The fact that this is possible at high speed is demonstrated by its use on pick-and-place robots.
The gripper, which does not really correspond to the German Engineering approach, can also be used with cobots.
The book "Introduction to Human-Machine Collaboration" gives you a good overview of the world of human-robot collaboration for little money. The author of this blog is available for a walk through your production/manufacturing(detail) to then provide concrete cobot suggestions.
