Tensegrity Robotics
What is Tensegrity?
Tensegrity refers to the design concept where the integrity of a system is realized through suspension of discontinuous compression elements in a continuous sea of tension. Remarkably, tensegrity is pervasive from a cosmic to atomic scale. The universe is a system comprising of discontinuous compressive elements (cosmic spheres) that maintains its structural integrity due to principles of tension that we identify as the gravitational forces. Tensegrity concept can also be seen to form the architectural basis of atoms, cellular mechanotransduction and even the human musculo-skeletal system (joints, spine). For example, the compressive bones are suspended within a sea of tensile ligaments and muscles, and the loss of tensile stress leads to problems like osteoarthritis, where the bones scratch against one another.
