We are interested in the application of dynamical systems theory to the invention and construction of intelligent machines and systems, with a particular focus on biologically inspired robotics. Many of us have worked in robotics with emphasis on dynamical dexterity and the management of kinetic energy in designing machines capable of performing useful work on their bodies and environments. Others of us have worked on more abstract problems of control and coordination with the object of developing new methods of design and analysis toward the construction of such machines.
