Description

Look at eight numbered items in a schematic desk scene with a robot arm and classify each one as a pinch point, a collision hazard, an electrical hazard or acceptable. Used in Chapter 3.

The scene is a schematic, not a photograph of a real desk. The left part shows the desk from above: an SO-ARM101 follower inside a taped circle (its work envelope), a laptop, a power supply with its cable, a cup of water, a sleeve and an E-stop button. A view from above cannot show the gripper jaws or the gap at the elbow, so the right part shows the arm from the side, drawn by the shared robot-arm-lib.js library.

Each of the eight items has a numbered ring. In the quiz, the ring of the item being asked about is drawn thick and red.

Lesson Plan

Grade level: Middle school and up (age 12+). Time: 5 to 10 minutes.

  1. Explore. Hover over or click each numbered ring to read the name of the item. No classes are shown yet.
  2. Start the quiz. Choose Quiz in the menu. The sim highlights item 1.
  3. Classify. Ask how the item could cause harm: by trapping, by striking, by electricity, or not at all. Press one of the four class buttons. You get one attempt per item.
  4. Read the reason, then press Next item.
  5. Review. The last screen lists the eight items with their classes. Mastery is 7 of 8.
  6. Think about it. Three of the eight items are pinch points, and only one of them is the gripper. What do the other two have in common with it?
