Engineers create robotic bird that can grasp branches

Engineers have created a falcon-inspired robot that can take-off, land and grasp branches just like a real bird – and even catch objects in the air. Developed by a team at Stanford University, SNAG (stereotyped nature-inspired aerial grasper) replicates the impressive grasp of peregrine falcons. In place of bones, SNAG has a 3D-printed skeletal structure – which took 20 iterations to perfect – as well as motors and fishing line in place of muscles and tendons. Thanks to a quadcopter drone attached, SNAG can fly around in its quest to catch and carry objects and perch on various surfaces. Coupled with cameras and sensors, SNAG could be used for monitoring the climate, wildlife and natural ecosystems – as part of efforts to prevent forest fires for example – as well as for search and rescue efforts.
