Stanford engineers create a perching bird-like robot
With feet and legs like a peregrine falcon, Stanford University engineers have created a robot that can perch and carry objects like a bird.
“It’s not easy to mimic how birds fly and perch,” said William Roderick, PhD ’20, who was a graduate student in both labs. “After millions of years of evolution, they make takeoff and landing look so easy, even among all of the complexity and variability of the tree branches you would find in a forest.”
Years of study on animal-inspired robots in the Cutkosky Lab and on bird-inspired aerial robots in the Lentink Lab enabled the researchers to build their own perching robot, detailed in a paper published Dec. 1 in Science Robotics. When attached to a quadcopter drone, their “stereotyped nature-inspired aerial grasper,” or SNAG, forms a robot that can fly around, catch and carry objects and perch on various surfaces.
