A palm-sized "robo-bat" with shape memory alloy jointed limbs and smart material alloy muscles is being built by North Carolina State University researchers. It's the perfect micro air vehicle (MAV) for surveillance or other kinds of data gathering — Batman could fit this gadget easily onto his utility belt.
Gheorghe Bunget, a doctoral student in mechanical engineering at NC State, and his advisor Dr. Stefan Seelecke looked to nature for inspiration. "We are trying to mimic nature as closely as possible," Seelecke says, "because it is very efficient. And, at the MAV scale, nature tells us that flapping flight – like that of the bat – is the most effective."
