Inspired by this, I led a group of 5th graders and high school students through a "peanut butter and jelly sandwich robot" exercise.

I had a blast and so did the kids.

We had them list some steps to make a pb&j sandwich, and then I, as the robot acted the steps out as literally as possible.

When they said "gather materials", I went around the room and picked up erasers, markers, water bottles; whatever I could find.

When they said "put the knife in the peanut butter" I stabbed the (plastic) knife through the cardboard seal.

When they said "put the peanut butter on the bread", I put the jar of peanut butter on a slice of bread.

After all of that we showed a video of an industrial robot applying sealant, just like we spread the peanut butter and jelly.

At the end we asked how we could have done it better, and one of the kids said "Get a smarter robot"

I'd highly recommend doing something like this for a STEM day, or just for fun.
