Part of my engineering curriculum was a very fun hands-on robotics course. A robot like this one can move so fast that you don’t have time to get out of its way. Factories that use robotics will have black-and-yellow danger lines on the floor around around each workstation and flashing lights on top of the robots. The factory floor looks like a crazy Christmas show, especially when the lights are low.
A workstation ideally is defined as the maximum reach of the robot, not the extents of its motion in a given job, so that if there is a mechanical failure or a glitch in the program nobody gets surprised.
For the clueless, there are also multiple emergency stop switches. I can’t tell whether the fellow twirling around on the robot-ride end effector in this video has an emergency stop switch within reach. I kind of doubt it. Not that he’d have time to actually use it.
Breaking the rules is fun.
