There are clear perimeters set in industrial settings when robots are in operation for this precise reason.

I'm sure the devs could have used much lower force values when dealing with the prices or put logic in place where if a hand is on the board the robot disengages. Hindsight is 20/20..

Looked horrific could barely watch for a few seconds.

Not every robots has force sensors and configurable force settings. Some only has overcurrrent error reporting, or only take positional inputs.

The “correct” way to do this is to use weakened “cobot” type robots that are specifically designed to be operated around humans, add at least a laser fan-beam fence that robot is not allowed to move while any object is detected by it, and put a big red button somewhere with a guy in charge of pressing it as well.

The fence is a must at the very least.
