This video details what we learned from our first and failed attempt at building a compliant mechanical neural network for the purpose of demonstrating the ability for an architected material to autonomously learn desired mechanical behaviors and properties. Although, the attempt failed and the machine never successfully learned any behaviors, it ironically taught us more about the learning process than the next improved design that did successfully demonstrate learning. Thus, this video explains all that was wrong with our first attempt and what improvements were necessary to enable a physical compliant mechanism to autonomously learn.
To better understand the contents of this more advanced video, it is recommended that you first familiarize yourself with the fundamental concepts by watching this seminal video titled, “Compliant mechanisms that LEARN! - Mechanical Neural Network Architected Materials.”
