Do Humanoid Robots Need Legs? The Surprising Logic Behind Robot Design Choices

Do robots really need to look—and move—like us? What physics and practical needs are driving these decisions behind the scenes?

I talk with Pras Velagapudi, CTO of Agility Robotics, about why their team settled on a humanoid robot design (with legs!), how real-world constraints shape robotics, and the logic behind choices that go far beyond following trends.

You'll like this interview if you're interested in robotics, automation, engineering tradeoffs, or the practical side of how machines are designed to do useful work alongside people.
