Microfiber Arrays

This paper reports enhanced adhesion and friction of biologically inspired mushroom-shaped elastomer microfibers which are fabricated using micromolding and the notching effect during deep reactive ion etching (DRIE). The fabrication approach of this work allows mushroom-shaped small diameter fibers down to 100s of nanometer scale (using interference lithography) with high uniformity, and high yield in large area. The fabricated microfiber arrays demonstrate approximately up to 17 time higher adhesion and around twice higher static friction than the nonfibrillar flat elastomer surface on a 6 mm diameter glass hemisphere. Moreover, adhesion experiments with the microfiber arrays which have different thickness backing layers reveal the significance of the backing layer thickness on adhesion of the fiber arrays on smooth contact surfaces.

Compliant Actuation

This chapter outlines a number of research lines that, starting from the observation of nature, attempt to mimic human behavior in humanoid robots. Humanoid robotics is one of the most exciting proving grounds for the development of biologically inspired hardware and software—machines that try to recreate billions of years of evolution with some of the abilities and characteristics of living beings. Humanoids could be especially useful for their ability to “live” in human-populated environments, occupying the same physical space as people and using tools that have been designed for people. Natural human–robot interaction is also an important facet of humanoid research. Finally, learning and adapting from experience, the hallmark of human intelligence, may require some approximation to the human body in order to attain similar capacities to humans. This chapter focuses particularly on compliant actuation, soft robotics, biomimetic robot vision, robot touch, and brain-inspired motor control in the context of the iCub humanoid robot.
