Introducing: Season 2 of 30 Animals That Made Us Smarter
Summary
Host Patrick Ayi explores how the elephant’s trunk inspired the Bionic Handling Assistant, a soft robotic arm developed by Festo. The episode details how engineers mimicked the trunk’s 40,000 muscles and pneumatic movement using 3D-printed plastic and compressed air. This innovation creates safe, flexible robots for human-robot collaboration, launching the field of soft robotics.
