RoachBot to the Rescue! Meet the Six-Legged Cyborg Superhero Built for Search and Rescue Sep 28, 2026

Show notes

It's a bird! It's a plane! It's... a robot cockroach?

This adventure is packed with movie-theater mayhem, hilarious hijinks, scientific surprises, and one seriously superpowered six-legged hero. By connecting laughter to learning, this cockroach episode shows how scientists can look to the natural world for unexpected solutions to some of humanity’s biggest challenges.

In this episode, kids and families will discover what a cyborg actually is, and how scientists can combine living organisms with technology.

What can't RoachBot handle?!
