Animals routinely perform motor behaviors that are beyond the abilities of current robots. A cockroach navigates uneven terrains at speeds that are unmatched by any machine. Most humans, even with cold and numb fingers, can handle objects with far greater dexterity than the most precise robot. On the other hand, compared to animals, robotic joints are more precise, motors have higher force and power output, sensory feedback control is faster, and computations are more repeatable. How do apparently sloppy animals outperform the fast and precise robots that we build? Are animals better because of, or despite their sloppiness, i.e. how do the body’s mechanics affect control? My research, straddling the areas of Mechanics, Control theory and Biology, aims at extracting the design and control principles that underlie the deftness of animal motor behavior, and translate that to next generation actuators, robots and prostheses. A common thread to the various projects in my lab is to develop systematic methods for biologically inspired mechanical designs that alleviate the need for precise and fast continuous feedback control.
We use a combination of techniques ranging from human biomechanical experiments to theory and computational models. More recently, we have started to build passive and actuated analogs, i.e. robots, to further develop, test and apply our theories.
