[music] Hey it's me Destin welcome back to Smarter Every Day. I'm in Caleb's room. Caleb is a science fair winner, so he is legit, and you dropped the cat in the cat drop video right? - Yes.
- And we had a deal right? I paid you with something. What did I pay you with? - These Lego motors.
- That's pretty cool. But I called you and I said I want yo... Read More
Key Insights

Questions & Answers
Q: How does the Lego inchworm work?
The Lego inchworm operates with a battery-powered motor that turns the axle, worm wheel, and cam, while a ratchet ensures smooth movement without backtracking.
Q: How do the caterpillars in the rainforest move together as a group?
The caterpillars use a stop and think technique, where the movement propagates from the back to the front, indicating a collective decision-making process.
Q: What did the Lego drag race experiment reveal about caterpillar locomotion?
The drag race showed that a group of caterpillars moves faster and more efficiently than a single caterpillar, with each additional level of caterpillars increasing their speed.
Q: How do caterpillars communicate with each other?
Caterpillars communicate through tactile communication, as observed in their synchronized stops and starts during locomotion.
Summary & Key Takeaways
-
Caleb builds a Lego inchworm using motors and demonstrates how it functions with a ratchet mechanism.
-
Destin explores the unusual locomotion of a group of caterpillars in the Amazon rainforest.
-
Lego drag races show that caterpillar groups move faster and more efficiently than individual caterpillars.
