Drawing the table and the box changes what you notice about robot safety
A passage from a Japanese industrial-robot book (鉄の身体論) that I found practical.
Chapter 6 asks you to draw the work cell on paper. Draw the arm. Then draw the table. Then draw the box the parts go into.
Looking only at "can the arm touch a person" sends your attention to the tool speed. Add the table and you start seeing a hand getting between the part and the surface. Add the box and you have to think about where a dropped part ends up.
The book is explicit that this is not a way to certify a cell yourself. The purpose is narrower: to be able to ask, concretely, which situations were included in the assessment you were shown.
I liked it because it turns "is it safe?" into "what was actually checked, and in which situations?" — a question you can ask without being an integrator.
