A team of engineers and roboticists at EPFL in Switzerland has designed and built a gliding drone that can use its wings as a gripping tool to perch on a vertical object. In their project, reported in the journal Communications Engineering, the group created a drone inspired by animals such as bats that can land on vertical poles and tree limbs.A team of engineers and roboticists at EPFL in Switzerland has designed and built a gliding drone that can use its wings as a gripping tool to perch on a vertical object.
