Science Robotics

Stable approaches to landing.Unmanned aerial vehicles (UAVs) are affordable tools for many tasks, such as surveillance and delivery, but constant motion quickly drains their batteries. Flying animals are able to attach to or perch on top of structures, conserving energy between tasks. Hang et al. designed modular, actuating landing gear that attached to a commercial, off-the-shelf quadrotor UAV. The UAV was able to approach objects without collisions and actuate the landing modules to perch on and/or grasp objects without damage. It also maintained its position once stabilized, allowing continued surveillance with low energy use. [CREDIT: KAIYU HANG/YALE UNIVERSITY]
