Robotic Bats Fly, Flexing Their Tiny Metal Muscles
Researchers are making robotic surveillance bats complete with metallic muscles and shape-memory alloys What could be more effective and potentially terrifying than spying on your enemies with robot bats? That what researchers at North Carolina State were thinking when they started working on creating robotic versions of the furry fliers. The idea is to create micro-aerial vehicles, or MAVs, that would be used for surveillance or detection of weapons. However, most MAV prototypes use fixed-wing body shapes, which don’t provide the same level the maneuverability that nature’s flapping wings do. The answer would be robot bats that use innovative technologies that mimic nature’s joint and muscle systems. The researchers have already created a prototype of the skeleton of the robotic bat, which weighs a skant 6 grams. The next step is to create the joints that connect the skeleton, crafted out of...
