Like the guy at my Imbissbude (snack stand) always tries to do, I mean?
BratWurst Bot was built using a set of common parts run by a flexible, adaptive software package that can interact with members of the public. It’s based on a Universal Robots UR-10 arm equipped with Schunk PG-70 standard parallel gripper hand and a very standard pair of grill tongs. The bratwursts were conveyed from an ordinary tray to a regular gas grill before being plated and served.

The old fashioned Imbiss used to be a operator owned business to a greater extent that it is now. So, I’m pretty sure that this is more than just a novelty, but rather a way of getting around having to carry another employee.
