Dynamic Tensegrities: Foundation for Motion and Thought<\/strong><\/p>\n Vytas SunSpiral <\/strong><\/p>\n <\/strong><\/p>\n Friday, December 7, 3-4pm There is a fundamental connection between understanding our daily human experience and understanding how we move. Our brains exist to coordinate motion, so if we wish to understand how we think, feel, and relate to others, we should start by understanding how we move. The control of human and robotic motion is intimately tied to the structure that is being moved, and emerging theories of vertebrate physiology are overturning the traditional bone-centric model of the body in favor of a fascia-centric model where the primary load paths are in the continuous tension network of the soft-tissue. Tensegrity structures distribute forces globally through a continuous tension network while their compression elements do not touch or pass compressive loads to each other. They have many physical properties, such as high strength to weight and multi-path force distribution, which make them ideally suited for robust motion through dynamic natural settings, yet pose new challenges for controls.<\/p>\n This talk will discuss the unique properties of tensegrity structures and how they appear to be a foundational part of our bodies and how we move. Challenges in controlling tensegrities will be discussed, including thoughts on how they may be especially appropriate for \u201cCentral Pattern Generator (CPG)\u201d based oscillatory controls, enabling a natural coupling from controller to structure to environment. \u00a0Finally, the talk will conclude with an overview of my current research into dynamic tensegrity structures, both physical robots and physics based simulations, whose purpose is to be a platform for controls research.<\/p>\n Vytas SunSpiral<\/strong> is a Senior Robotics Researcher in the Intelligent Robotics Group within the Intelligent Systems Division at NASA Ames Research Center. His primary research interest is in understanding physical interaction with dynamic unstructured (natural) environments.<\/p>\n
