Jum** is a locomotion strategy widely evolved in both invertebrates and vertebrates. In
addition to terrestrial animals, several aquatic animals are also able to jump in their specific …

Small aerial robots are limited to short mission times because aerodynamic and energy
conversion efficiency diminish with scale. One way to extend mission times is to perch, as …

A primary determinant of movement strategies is travel speed, which modulates both power
consumption and distance travelled and thus varies according to ecological circumstance …

An approach is presented whereby small, unmanned aircraft can land on walls. The
approach is demonstrated with a plane that uses an ultrasonic sensor to initiate a pitch-up …

Animals use diverse solutions to land on vertical surfaces. Here we show the unique landing
of the gliding gecko, Hemidactylus platyurus. Our high-speed video footage in the Southeast …

In nature, cockroaches run rapidly over complex terrain such as leaf litter. These substrates
are rarely rigid, and are frequently very compliant. Whether and how compliant surfaces …

The world's gliding mammals are an extraordinary group of animals that have the ability to
glide from tree to tree with seemingly effortless grace. There are more than 60 species of …

Animals that glide produce aerodynamic forces that enable transit through the air in both
arboreal and aquatic environments. The relative ease of gliding compared with flap** …

Although many cylindrical animals swim through water, flying snakes of the genus
Chrysopelea are the only limbless animals that glide through air. Despite a lack of limbs …

We present the first results of a system that allows small fixed-wing UAVs to land and cling
on surfaces such as brick walls using arrays of microspines that engage asperities on the …
