Description

Do robots really need to look—and move—like us? What physics and practical needs are driving these decisions behind the scenes?<br><br>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.<br><br>You&#39;ll like this interview if you&#39;re interested in robotics, automation, engineering tradeoffs, or the practical side of how machines are designed to do useful work alongside people.<br><br>TRANSCRIPT<br>- https://audrownashpodcast.com/episodes/24-agilityrobotics<br><br>EPISODE LINKS<br>- Pras Velagapudi&#39;s website: https://pras.ai<br>- Pras Velagapudi on LinkedIn: http://www.linkedin.com/in/pvelagapudi<br>- Agility Robotics website: https://www.agilityrobotics.com<br>- Agility Robotics on X: https://x.com/agilityrobotics<br>- Agility Robotics on LinkedIn: https://www.linkedin.com/company/agilityrobotics<br><br>PODCAST LINKS<br>- Podcast Website: https://audrownashpodcast.com/<br>- YouTube: https://www.youtube.com/@audrow<br>- Apple Podcasts: https://podcasts.apple.com/us/podcast/audrow-nash-podcast/id1716486786<br>- Spotify: https://open.spotify.com/show/74jWpWiLwsasY2QHtDcl8I?si=6c92796bf9554162<br><br>TIMECODES<br>(0:00) Start<br>(0:42) Agility Overview<br>(5:29) Why Humanoid Design<br>(13:31) Why Legs, Not Wheels<br>(23:19) Digit’s application<br>(38:26) Safety in Humanoids<br>(49:15) Standardizing Safety<br>(1:06:50) Digit in Other Industries<br>(1:15:06) How AI Fits into Robotics<br>(1:29:23) Is Data Still Gold?<br>(1:35:57) The Future of Agility<br>(1:38:16) Key Takeaways
